Thank you guy! You're really helpful! :) I subscribed because too many videos I'd search how to make hydrogen fuel cell, I found your video. Again, thank you! I subscribed. :)
Thanks ！
Excellent works, very good.
Thanks
Nice clean build! What is the volume output of H per minute? What is the voltage and amperage draw? Thanks!
Thanks for your appreciation. H2 production：300ml/min. Voltage 3.4~4V, current 10~20A
Hi, well done. This is a very interesting video that shows a lot about the technology. I have one question though. I have seen many of these outer plates (aluminium) and they all have channels for the water to flow. I have not seen these channels in your plates. How does water flow? Thanks for the video and I do appreciate if you can clear things up to me. Oh, I am already looking at your website, interesting.
You can pause to view the section on our preparation materials. You will find 10 holes in the metal plate. More than the 8 holes needed for the 8 screws.Depending on the location and electrode, these holes function differently.
Hello! I am intrested in build a very small model of my own for research, using individual parts, and I have a few questions about the parts themselves. To start, I will be building this on a small scale (effective area of MEA and microplates 5 x 5 cm) where would I be able to get positive and negative titanium alloy electrode plates at this scale (roughly 8 x 8cm-ish is what I am looking for)? Another question I have is where do you get your specialized silicone gaskets? And would I be able to get them on a similar scale as previously stated? My last question is do you need the small, medium, and large titanium mesh in order to run it, or would a microplate serving as a GDL and electrode work just fine on a smaller model? Thank you for your time.
All our parts are custom made in our own factory (including screws). At the same time we do not recommend that you build this system alone. This is because the lack of experience and machinery during your assembly process can lead to inefficiency or even damage to the proton membrane. Take for example the final tightening of the screws. If you tighten them too hard you can damage the plasma membrane, if you tighten them too hard you can cause leakage.
For more information on BBP, you can see our video on dismantling a PEM electrolyzer by clicking here(ruclips.net/video/N-uOW0DNDO0/видео.html). We are using two titanium meshes (one with a large grid and one with a small grid).
Great! One question, how is the hydrogen output different from the oxygen output if all electrodes are in the same chamber?
The hole for the hydrogen output and the hole for the oxygen output are not the same. It is not the same. Hydrogen is output separately, oxygen and water are output together.
The titanium plates are the bipolar plates right? I mean the electrode material/or electrocatalyst is on the membrane-electrode assembly (from dupont) no?
yes
Interesting video. Do you know why the nafion membrane is black? because neat/pure nafion 117 is translucent right? Is there an additive in the membrane and do you know what this is?
Yes, neat/pure nafion 117 is translucent.neat/pure nafion 117 is translucent.Given that the anode of a PEM electrolyzer is in a highly acidic environment, most non-precious metals are prone to corrosion and might potentially combine with the sulfate ions present in the PEM, thereby reducing the PEM's proton conductivity. Hence, it is necessary to spray a coating on both sides of the membrane. The best choice for this coating is IrO2, followed by Pt, Ru, and other precious metal/oxides and their binary and ternary alloys/mixed oxides. Notably, IrO2 is black in color.
What are the microplate and mesh for? Could you just install the PEM without them if it was secured and it does not touch the end plates?
This is the gas diffusion layer, also known as GPT, which is a porous layer sandwiched between the cathode and anode and the bipolar plate. GPT acts as a bridge connecting the bipolar plate and the catalyst layer, ensuring gas and liquid transport between the bipolar plate and the catalyst layer, and providing efficient electron conduction.
At the anode, liquid water is conducted through the gas diffusion layer to the catalyst layer, where it is decomposed into oxygen, protons and electrons. The generated oxygen flows back to the bipolar plate through the GPT, the protons are conducted to the cathode through the proton exchange membrane, and the electrons are conducted to the anode side bipolar plate through the GPT and then enter the external circuit.
At the cathode, electrons enter the cathode catalyst layer through the GPT from the external circuit, and react with protons to generate hydrogen gas. The generated hydrogen is collected by the GPT to the bipolar plate. Therefore, in order to ensure gas and liquid transport efficiency and electrical conductivity, GPT needs to have both appropriate porosity and good electrical conductivity to ensure electron transport efficiency.
Great work, but I have some questions.
First , is water going through all this stack ? and how ?
Second question, is the micro plate that important? Or can I just use diffusion layers ?
1.Water only passes through the anode, and excess water exits the anode along with oxygen.
2.Micro plate is very important.Micro plate is gas diffusion layers(GDL).Ti mesh and Ti alloy positive is BPP.
I actually have a question whether bipolar plates are in direct contact & hence complete circuit or circuit is completed by H+ ions generated at PEM?
There are two current collectors at the end, one at cathode side and the other at the anode side. These are connected by an external supply that completes the circuit
What is the function of the microplate? Is the microplate the electrode or is the electrode material included in the dark layer on the PEM along with the catalyst material?
They are GDL. The gas diffusion layer or called the current collector GDL or PTL, as an electronic conductor between the MEA and BPP, ensures efficient mass transfer of liquids and gases between the electrodes and the BPP.
At the anode, the liquid water transports from the passages of the BPP to the catalyst layer on the membrane through the current collector, where the water is decomposed into oxygen and protons. The oxygen generated here diffuses in the opposite direction through the current collector into the flow passages.
At the cathode, liquid water and hydrogen are transported from the membrane to the passages of the BPP through the current collector. Electrons start from the catalyst layer on the anode side, pass through the current collector and BPP, and then reach the cathode side. In PEM electrolyzers, the anode potential is high enough to oxidize carbon materials and other materials must be used. Titanium is often a choice for current collectors at the anode.

Do the bipolar plates act like electrode?
And how could the water go through the stack as I don't see channels for the water to pass.
They are transmitting through channels.
You may not be able to see it clearly in the video. You can see pictures in this post.

What is the maximum current that can be applied to the cell? It depends on the membrane area, right? As part of my thesis, I developed an electrolysis cell with a membrane area of 5 by 5 centimeter. How can I determine the maximum operating current for this?
The maximum current that can be applied to an electrolyzer does indeed depend on the effective membrane area. Current density (current per unit area) is a key parameter in electrolysis and can vary between different types of electrolyzers and electrolytes.
Typically, water hydrogen electrolyzers have a maximum current density of around 1-2 A/cm2. This is a rough guideline, and actual values may depend on many factors like the specific electrolyte used, temperature, electrolyzer design, etc.
For a 5 cm x 5 cm electrolyzer (i.e. 25 cm2 area), if we use the guideline value of 1-2 A/cm2, then theoretically the maximum current would be around 25-50 A. However, keep in mind this is just an estimate, and the actual optimal current may be lower, especially if you want to maximize electrolyzer lifetime.
To determine the actual maximum working current for your specific electrolyzer, you would typically do a series of experiments where you incrementally increase the current while monitoring electrolyzer voltage and gas production rate. If the electrolyzer voltage starts rising rapidly or the gas production rate levels off or decreases, this indicates you are approaching the performance limit of the electrolyzer.
@@senzahydrogen Thanks for the quick reply. I have another question. What is the function of the titanium mesh?
@@timrohr5920 Bipolar plates (BPP) are flat separator plates (either with metal mesh or screen lamination or with etched flow field channels thick metal separators) used to match the power supply voltage by stacking multiple electrolysis cell units in series. Separate adjacent units and connect them electronically. It needs to have low low resistance and high mechanical and chemical stability, fluid distribution, and high thermal conductivity as it also helps to promote heat transfer.

How can i determine me PEM Electrolyzer dimesions depends on Hydrogen production rate?
It seems you want to understand how to determine the size of a PEM (proton exchange membrane) electrolyzer based on the hydrogen production rate.
However, there are several factors to consider when sizing a PEM electrolyzer, including:
Desired hydrogen production rate: This is the most important factor as it directly determines the required current throughput of the electrolyzer. Higher hydrogen production requires a larger electrolyzer.
Efficiency of the electrolyzer: This depends on the specific electrolyzer technology and operating conditions used.
Operating pressure: If the electrolyzer runs at high pressure, it may require a larger size to maintain efficiency.
Electrolyzer materials and design: These factors also influence electrolyzer size and performance.
Current density: Higher current densities yield more hydrogen but may reduce energy efficiency of the electrolyzer due to greater voltage losses at high current densities.
I suggest first consulting with relevant professionals to determine the optimal electrolyzer size based on your desired hydrogen production rate. If you are looking to customize an electrolyzer system, you can also contact us(service@senzahydrogen.com) for assistance. Our team has experience designing and sizing electrolyzers for various hydrogen production applications.

Hello. What material is the microplate made of?
It is also called the Gas Diffusion Layer (GDL).It is electronic conductor between the MEA and BPP, ensures efficient mass transfer of liquids and gases between the electrodes and the BPP.Its material is titanium
thank you for the answer. Is this microplate also available in other materials? And where can I buy this microplate? Where can I buy all the parts to make that generator ?
@@farugmagsud At the moment, no better alternative material has been discovered, as the GDL needs to simultaneously meet the requirements of corrosion resistance, porosity, and good electrical conductivity. Regarding the purchase inquiry, we also sell PEM electrolyzers. You can contact us at email: service@senzahydrogen.com.
any alternative for titanium alloy electrode ?
No , There is no better alternative. We have also tried other materials, but they are very susceptible to corrosion. Their working lifespan is very short.
@@senzahydrogen can you tell me name of that alternative you tried

Third, all of our hho car kits require a microcomputer. The microchip program corrects the engine parameters and adjusts the ignition timing and shift timing, which can improve the fuel combustion efficiency of the engine under low operating conditions.

The requirements for catalyst materials are extremely demanding. A reminder that meets this requirement
Chemical materials are limited to certain precious metals.
Metal stability: Au > Pt > Ir > Ru > Os

Our video is the method of making pem electrolytic cell. And what you are talking about is the method of making alkaline electrolyzer. The two are different, you can refer to this article senzahydrogen.com/hydrogen-production-from-electrolysis.html.
Yes, there is no good solution to the safety of hydrogen storage yet.
@senzahydrogen wrong, that's not a pem cell. Proton exchange membranes are made to capture current to be used, not to apply current...that's an electrolysis hydrogen splitter. Useless without a pem..
