This oxygen detector as a replacement for much expensive hydrogen detector (must be very accurate) is a great idea! Looking forward to you new setup!
Super cool!
Can't wait to see the final generator
At last! Great job! This is the most interesting project I have seen so far.
Been patiently waiting for this :) amazing work and some great ideas!!
excellent.
Incredible
Great project! Thanks for sharing.
I hope you will update this video after few weeks/months of testing. Can you please give us links to the membrane and oxygen detector you are using? If I remember correctly you did say something about hydrogen detector - how it's going? Any news about it? DIYself hydrogen detector would be nice, cause those in stores are quite expensive... Anyway GREAT project, and some amazing ideas!
Super super
Fantastic project! Keep going! 👍
fantastic job
Enjoying your videos!
Muy buen trabajo 👍
ha just a reminder the air line must be above the air intake to get read of the bad gas. your not venting bad air the way you have it in the video. please stay safe we all need you alive.
Holy shit. I just watched a video of yours and checked the channel how the fuck have I not found you yet my god your channel is amazing I can't wait to watch it all... Love the way you explain things man nice 1
Thank you so much!!! Pleas spread the word!
Awesome video!
Great job!
Very informative, thanks once again... Thom in Scotland
Right ok, I've watched this now. Brilliant video, brilliantly explained I will try this myself and you have a new subscriber (me). If you're in the UK, pm me your details and I will order you the graphite sheet to play with. Graphite and neoprene rubber will stop this and potentially be more efficient, would love to see someone like you try it, and decide if it's good or not, I have found some interesting results.
Credentials? I'm a massive massive nerd, watched many lectures and have started to design my own hydrogen boilers. Look forward to hearing from you 😉
Thanks! I'm in the Netherlands. What type of graphite is that? Because te graphite I tested had quite a high resistance.
love your channel keep it up 👍
Nice video, thanks a lot for your work and for show to us :)
I used the same cloth material as (swim shorts) for the membrane. Polly nylon or polyester I believe this material is very chemically resistive. And will not let air through easily as well. Like when you jump into the pool and have a big bubble in your shorts.
Hello. I got a low cost poreless ionic membrane but p acid solution. Membrane electrolyser is OK. But I have to solve negative electrode wear.
For alkaline solutions, there are those used in PEM cells, but they are very expensive. I am trying solution to use nickel and alkaline solution.
I liked your lab. Good luck.
Awesome vid, I wish you extreme success in all that you do!
Very good results. I want to replicate something like this. What thickness of copper plate do you use?
This plate is 0.8mm thick.
Great video as always. When will the Solar panel part 3 release?
Thanks!! On the 21st of june the sun will be at its highest point so then I can film it. So I think the video will be uploaded mid july.
First to comment !
BTW nice work there
Edit: OOOH! those glass snapping are so satisfying
agree, glass snapping was very well edited, mesmerizing!
Next video now please 👍👍👍👍👍
Patience my friend. Do you follow me on facebook or instagram? Because there you can see what I'm currently working on. Or you can become a Patreon for more extra special behind the scenes stuff.
❤👌
Interesting video thanks, however, for the uninitiated, NEVER double up gaskets, not even using gaskets of rubber insertion and a secondary layer of silicone, use one or the other but never both together ....for they are dissimilar materials, wi different expansion and contraction ratios and WILL seperate and LEAK ... In due time... If no the day then some day soon.... So...
I really appreciate your video...

That's great I hope it works great for you for a very long time. You can find stainless steel sheet free if you can find someone throwing away certain restaurant equipment,it's a lot of work getting it all apart but it beats having to buy it, I salvaged some once years ago but sold it because I needed the money for tobacco, thankfully I have manage to beat that habit/addiction. I'm glad to see you getting that back together.
Thanks! I don't want to use stainless steel anymore because of the chromium problem. But thanks for the suggestion! 👍
@@TheDIYScienceGuy Titanium will get rid of the chromium problem and is not much more expensive than stainless steel.
The problem is, is that titanium is a very bad conductor of electricity. But thanks for the suggestion! 👍
@@TheDIYScienceGuy titanium is used for electrodes in PEM generators as it doesn't oxidise causing problems for the ruthenium iridium catalyst. We build them and they seem to conduct electricity just fine.
Don't they use platinum for that?
Hello and a big congratulations for your tutorial they are very interesting. can you tell me what kind of membrane you use and where you buy them? thank you very much 😊
Thanks!!! This is what I used: www.amazon.com/Kimberly-Clark-33560-Polypropylene-Kimtech-Surface/dp/B00UBGXXS4 hope it helps!
Very well made electrolyser and quality of the process is perfect! To check if there is any oxygen in hydrogen just make a spark inside hydrogen sample balloon (if there is no flame after spark inside ballon with a sample then that means no oxygen in a sample). Regards!
Thanks! Yes that would work but I don't want sparks of flame near/attached to my generator. But thanks for the suggestion! 👍
@@TheDIYScienceGuy of course safety is most important so once you fill up a small sample baloon from the main h2 storage container then do the test in safe place far from the generator and preferrably outdoors. You can use a gas cooker spark igniter or somethin like that. Then for comparison add some air to the sample baloon to see what happens when oxygen is mixed in sample.
Yes I used to do that with a soap bubble like I did in the video but I now want a automated system.
@@TheDIYScienceGuy That (the soap bubble test which is known as the pop test) is completely different to what Kapalek84 is suggesting - the spark occurs inside the balloon without letting any air in and is therefore used in the hydrogen to test for the presence of oxygen, if no oxygen, then no ignition of any kind.
You are looking for a very small amount of mixing of O2 and H2, so if you were to periodically spark the H2 gas and use a microphone to listen for tiny explosions you will have a continuous testing process. This will test for oxygen (or chlorine) in the Hydrogen from about 4-74% concentrated. This is a fairly high contaminant level in the H2 so the spark test is not particularly sensitive.
If that resolution is acceptable, then, although sparking sounds ultra dangerous, if you sample and isolate the gas and provide suitable safety features, then it is relatively safe. I would personally pipe the O2 a long way away and same with the H2 container - in opposite directions!
The idea is to isolate the testing sample in a small, thin glass tube with synced input/output valves, a pressure relief valve and embedded electrodes. A glass blower can build this for you.
If the contaminant is small, then the microphone will pick up a pop and will vent through a pressure valve which can just be a simple spring on a stopper arrangement.
The spark comes from two wires that are very close to each other in the tube with a suitable high voltage from a pulsed power supply. I suspect the wires will need to be replaced often since H2 is quite corrosive, so embed these in a suitable stopper that can be removed and replaced.

@@BenMitro Excellent information. Thank you all.
Respect of colleagues. If you remember, I asked you for advice on the choice of membrane material for separating hydrogen and oxygen. I'll confess without any secrets, I chose retex membrane material, thickness
300 um, and the electrolyzer separated hydrogen 100% well, but after 200 working hours of electrolysis it happens that occasionally a mixture of H2/O2 comes out of the hydrogen port, which is not good. I can't clarify what it is about... ?
Ok, wat type of fabric is retex?
@@TheDIYScienceGuy The Retex material is a non-woven textile based on polypropylene material
@@TheDIYScienceGuy I can't rationalize things, why does my dry cell electrolyzer sometimes separate H2 and O2 well, but sometimes it doesn't? I inserted a polyprolene cloth material as a membrane.
What a struggle I know the pain , leaking drives me crazy
Sir cant we use your split cell design in your #3 video by stacking many split cells together with neutral plates and pipes out of each hydrogen and oxygen chambers .
does it have drawbacks ? or why you chose not to use the chamber design stacking instead of
I'm looking to build the most cost effective hydrogen generator for an rc airship, would this be the best method for aluminum plates instead of copper? Not entirely sure how well it would electroplate and how well it would avoid corroding.
Nice idea! I don't know if you can nickel plate aluminum though.
Have you ever considered using graphene foil as the electroplate for hydroxide-oxygen generation?
Otherwise awesome workmanship and video! Thank you for sharing!
I've test with graphite rods from zinc-carbon "Heavy Duty" batteries in the past and the anodes would dissolve and the gas produced there wouldn't burn, leading me to believe it was creating CO2
@@chadw8164 hmmm that's an interesting problem. I know the idea of graphite foil is from Robert Murray-Smith(youtube name) but lookin at the research paper he refers to it does talk about the issue of high concentrations of electrolight destroys the anode side as you say. He also uses Urea as his electrolight.nit sure how that changes the corrosion. Wish he talked more about it www.researchgate.net/publication/273806853_A_Systematic_Study_on_Electrolytic_Production_of_Hydrogen_Gas_by_Using_Graphite_as_Electrode
Very interesting thinking outside box. Have question on comparison with steel that people scratch to get. More hydrogen. Can you test against against for results. The cost savings on yours would be considerable. Life expectency is also a question
Thanks! These are all thing I will find out later when it'a operational again.
Hi there Mr science guy:) how did the polypropelene cleaning product go in the Hgenny?
After 20 hours it was still OK. Long term test still needs to be done. But polypropylene is the most suitable material so I have high hopes for it.
@@TheDIYScienceGuy i'm keen to know how it holds up. Love your channel, great stuff!
@@johnking6188 I did watch "REPLACING GAS WITH HYDROGEN" and we have similar goal, cap the energy at day STORE IT, and release later on (at night for example), you have very nice setup, keep it up! I also want to compress hydrogen (non liquid state) and use it a a fuel in some engines. It would be nice to have a car/motor on hydrogen.
@spamator12 I have just started squashing the hydrogen into metal hydride in a home made tank. I'll post when I have data and footage. I agree, storage is the problem. Hopefully hydride in the mix offers solutions.
something tells me the reason the plating was happening only close to the anode was bc of insufficient current
i think a current source as opposed to a tension/voltage source would be better, but i'm no expert
just thought it's bc ions and charges are mostly neutralized closer to the contact, and saturating it with more charge than the electrolyte capacity would make platting even
Current is a result of voltage and resistance.
What are you powering with the hydrogen created?
Have you seen this video of mine: ruclips.net/video/llmcU-mZRFs/видео.htmlsi=XVQpuwWINdiGgtFc hope you like it!
what is the voltage and current used in this project
This is mentioned in the video. I'm not sure, I have to watch the video for that so maybe you can do that for me 😉
1.What are the dimensions of the plates
2. How large are the holes and how far apart are they
3. What are the dimensions of the gasket.
1. 250x250x0.5mm
2. The gass exit holes have a diameter of 9mm and are 150mm apart
3. Outside 250x250mm inside 210x210mm 4mm thick
@@TheDIYScienceGuy are the holes made to keep it together the same size and what is the spacing for those? Also I thought according to an earlier comment I saw the copper plates were 0.8mm thick?
@@TheDIYScienceGuy sorry about the fact I am asking so many questions. I am making a cad model. Also how far away are the water inlet and gas outlet holes including the width of holes from the plate?
Yes they are also 9mm
0.5 works but I could get 0.8 for free.
The inlet needs to be as low as possible. The outlets as far apart as possible. No problem, this is why I make these videos.
These are big copper plates. Where can I buy them in the Netherlands?
For this plate, I've got a big piece from the scrap yard, but for the other plates, I'm going to search the interwebs.
What is the difference in efficiency of the nickel plated copper plates vs stainless steel amps and volts/ litre of output
Less heat generation, but I'm not sure how much yet.
@@TheDIYScienceGuy I think they are also more durable.
How well has this new setup worked over the past year?
Well I've been building a new workspace over the past year. The generator has been running the amount of hours I mentioned in the video (don't remember how much it was) in a few Months I will plate more electrodes and build up the generator to its big size.
Can you link the product you used as a membrane?
Just look for: kimberly and clark pure polypropylene cleaning cloth. I can't find an international cellar, amazone only has small size.
Hello, can someone please help me? I'm currently trying to rebuild the generator, but I think I made a mistake with buying the membrane. I bought PolyPropilen 150g/m2, which is actually for weed control. Unfortunately, the material is completely waterproof and doesn't conduct electricity. So when I apply a multimeter, there is no resistance (Ohm) measurable. Can this even work like this? Unfortunately, I have very little knowledge, so I would appreciate scientific answers. It would also be great if someone could provide an Amazon link to a more suitable membrane material (in the EU). Thank you very much in advance.
Hi, the material needs to be permeable to water so the current can flow through it. This is what I use now: www.amazon.com/Kimberly-Clark-33560-Polypropylene-Kimtech-Surface/dp/B00UBGXXS4 hope it helps!
@@TheDIYScienceGuy thank you really much. Helps a lot!
When will the final gen video be posted?
That is a good question. It is definitely something I want to do, but I have so little time and so many other projects. But I think next year when I have the shed all up and running, I will continue the project. Thanks for sticking around!
@@TheDIYScienceGuy thanks for taking the time out and replying to me man means alot
Where to find pure propylene membrane material ?
Just look for: kimberly and clark pure polypropylene cleaning cloth. I can't find an international cellar, amazone only has small size.
@@TheDIYScienceGuy It's OK now. Alkaline electrolyzer with separation of hydrogen and oxygen, has been working perfectly for a full year using a polypropylene cloth, thank you for the advice. Finally, thanks to you, I found the right material for alkaline electrolyzer membranes :)😁
In your next video; check the audio volume before your publish it. This video has very poor audio quality. I wonder why it did not catch your attention.
Why not just use the pure nickel strips?
Because the resistance is to high.
@@TheDIYScienceGuy I am a bit confused why the resistance would be too high. These same strips are used for lithium batteries and the resistance is only 4x copper. The currents you are pushing are no where near causing this resistance to be significant, and you even mention you did not measure the difference.
It would work but I want the resistance to be as low as posible. A ratio of 4 would mean a lot more energy loss.
@@TheDIYScienceGuy why not make it thicker? You can use 2mm of nickel plates instead?´of .5mm copper . I think you loose a lot more in the wiring than you would loose even in a .5mm nickel plate since the plate has a huge cross of 125mm² with a resistance like a 30mm² copper AWG-2 cable
Pure nikle plates are expensive and I want the highest performance possible for this setup.
can you use baking soda so that the salt doesnt create chlorine gas from the electrolysis. now i see you have ventilation but you said it was for the nickel
I use vinegar and a small bit of salt. I don't think it's creating a dangerous amount of chlorine gas. The nickle vapor is much more of a "problem". Backing soda might react with vinegar creating sodium acetate and Co2 gas. But thanks for the suggestion! 👍
@@TheDIYScienceGuy so we should not use nickel? i also heard we should not use staineless steel due to chromium
No, nickle is much safer just use ventilation for the same reason as when you are cooking. 😉
@@TheDIYScienceGuy but i dont cook i only go to the drive thru lol
@@TheDIYScienceGuy i never cooked with nickel, only stainless steel or other teflon
Hello
Remove the membrane add metal sheet as a neutral
A natural pate products H2 on one side and O2 on the other, which means that you would have an H2 O2 mixture again. The membrane must be non conductive but permeable for the electeolite.
@@TheDIYScienceGuy oh I didn't know that okay
You can filter out oxygen by make liquid nitrogen surely you can filter it out
You mean by cooling down the gasses so the oxygen would condence out of it? Yes, that would work. Just a bit impractical but could be usefull for extra purification. Good thinking! 👍
@@TheDIYScienceGuy ruclips.net/video/XdE8xh1Y8go/видео.htmlsi=GjRgMb-CqDA_Z8f1
how will you capture the hydrogen and compress it into tanks to make it useful? this would be great if you could do this and turn a wankel rotary engine into a hydrogen electric generator
I show all that in this video: ruclips.net/video/REV739pRNcw/видео.html hope you like it!
Would you be willing to sell a small one?
No, I'm not selling anything, only charging ideas. Sorry.
Is any toxic byproduct ?
No byproducts, just nickle acetate.
how would you reverse plate a diamond layer on a steel plate as this Indian Nield Tyson suggests? ruclips.net/video/wAX8I35xw1o/видео.html
Please go back to the self-pyrolysis carbon generator!
Yes I definitely will!
Did you cut your finger?
No it's from a red marker. 😉
This is bad idea make with glas.
How thick and how large a squares are the plates you used? I am thinking of 12" x 12" square plates between 20 to 16 gauge thick. Are you being able to produce more hydrogen with the more efficient plates? How well is the Nickel plating holding up? Thanks, I need to replace my natural gas supplier with something because the new supplier jacked the price up double or more , I figure their intention is to do use like the did Europe, their goal is to exterminate 90% of the worlds population in a such a sneaky manner and make out like it was an accident.
Nickle holds up very well. I use 13 plates of 25x25cm(21x21cm effectively because of the seals) with a thickness of 0.5 mm
@@TheDIYScienceGuy the plates are 0.5cm or 0.5mm? 0.5mm is thin and would make it a lot cheaper to build but 0.5 cm is very thick and very expensive. Is it the greater the surface area the greater the volume of gas it will produce?Thanks
Yes, sorry, I meant 0.5mm. Yes, the more surface area, the more current will run, and the more gass will be produced.
