How to build a 2L/min alkaline hydrogen generator

How to build a 2L/min alkaline hydrogen generator
Current : 50A
Voltage : 12V
Rate : 2L/min
Catalysts : KOH(We recommend the use of KOH, and we have tested that NAOH is more likely to corrode stainless steel plates.)
Transformers : It is recommended to use transformers with constant voltage and current. This is because when the temperature rises, the current also increases. This can easily overheat and cause damage to the stainless steel plate.
In principle, 3 stainless steel plates can also produce 2 L/min of hydrogen. But the lifetime is very short and the temperature is very high. Our proposed solution is
(The diameter of the area involved in the reaction is 103mm)
1. Rate: 600 ml/min 15A, 12V, 3 plates
2. Rate: 1L/min 25A 12V, 6 plates
3. Rate: 2L/min 51A 12V, 9 plate, as well as a heat sink and a more advanced rubber ring.

Great! One question, how is the hydrogen output different from the oxygen output if all electrodes are in the same chamber?

[@bryaniskoo]

It isn't different. Comes out as Oxyhydrogen.

[@carfashion2]

50AMPS? YOU LOST YOUR MIND!!!!!!

[@CatboyChemicalSociety]

great video for pilot scale setups but you cannot or should not scale this up to industrial levels eg 1000A as those levels of oxyhydrogen increase the probability of things going wrong. Thus for scale up you need a pressurized alkaline electrolyzer with porous seperators to seperate H2 and O2 at the cost of some efficiency due to added resistance but still less expensive than membrane electrolysis.

[@senzahydrogen]

You're right. This is more of an experimental model to demonstrate a small alkaline hydrogen electrolyzer. For industrialization, more things would need to be considered, such as safety, maintainability, cost, etc.

[@CatboyChemicalSociety]

@@senzahydrogen still good enough for glass blowing torch feed

[@GraemeCox]

Shouldnt you be aiming for 2V at each plate? So if input is 12V in then there should be 5 plates between the - and + live plates? Also there should not be two live plates beside each other? If you fix that it might get you to 200W/L

[@CatboyChemicalSociety]

it is 2V per plate as you have 4 neutral plates between 2 charged plates leading to the voltage divider rule which allows for a nice 2V per plate. A rule of thumb is plate number = 1/2 of voltage input. so 12V = 6 plates and 24V = 12 plates and so on.

[@tuanquocle]

thanks, I'm trying to make one but it's hot. How can we reduce the heat?

[@senzahydrogen]

You need a transformer with constant current and constant voltage.

[@CatboyChemicalSociety]

use a heat exchanger to remove the heat dumped into the water. A general rule is heat produced = 1/2 of input assuming 50% efficiency the rest goes into heat so if you put 12V at 50A for instance you have 600W of input so 300W of cooling required for the water to not overheat or boil imagine having a 300W water heater device basically.

[@prabhu281]

Very nice, How much volt and amp are needed sir.

[@senzahydrogen]

Current : 50A Voltage : 12V

[@CatboyChemicalSociety]

voltage depends on plate stack where you have 2 charged plates and a given number of neutral plates. A rule of thumb is that you need half as many plates as your operating volts to ensure roughly 2 volts per plates which is a good overpotential for H2 and O2 generation. so 24 volt input means 12 plates per stack, 48V means 24 plates per stack and in this video 12V means 6 plates per stack. Higher voltage allows for less losses by wire as you can use thinner wires and carry same amount of energy using less current due to voltage divider. But dont go overkill and do 250VDC electrolyzer because any arc or short can cause an explosion.

[@freecrypto5263]

What is the appropriate size for the black strips separating the panels to make a suitable hydrogen cell for the car?

[@senzahydrogen]

Depends on the displacement of your car's engine. Different displacements require different rates of hydrogen production. More is not always better.

What is Alkaline?

[@senzahydrogen]

"Alkaline" is a word used to describe the property of a substance that can dissolve in water and make the pH of the solution greater than 7. In our daily life, some common alkaline substances include detergents, baking soda, and even handmade soap. In an alkaline hydrogen generator, "alkaline" refers to using an alkaline solution (such as sodium hydroxide or potassium hydroxide) to help decompose water and produce hydrogen gas. This is an efficient method because an alkaline environment can electrolyze water at a lower voltage. You can check this senzahydrogen.com/what-is-hydrogen-electrolyzer.html

[@enderates1430]

How can ı seperate oxygen and hydrogen for alkalin electrolyzer.

[@senzahydrogen]

Due to the principle of operation, it is difficult to separate hydrogen and oxygen directly in an alkaline electrolyzer. It may be necessary to separate the HHO gas in the outgoing HHO gas by means of special components or processes.

[@CatboyChemicalSociety]

@@senzahydrogen you can seperate it if you have a porous cloth between each plate stack along with half gaskets to act as feed lines for each compartment then have common input for water and 2 inputs for gases where half gaskets and full gaskets sit between the membranes and plates to have alternating output for each respective chamber. This however requires feed pressure and decent flow rate in order to accomplish seperation of product and the pressure, flow rate and input/output cross section needs to be fine tuned to prevent diffusion of microbubbles of H2 through the porous barriers. So yes you can seperate the gases with an alkaline electrolyzer and this is known as a pressurized alkaline electrolyzer. The H2 and O2 microbubble laden water enters 2 holding tanks that meet at the bottom with a pipe and a pump to re feed it into the cell.

[@CatboyChemicalSociety]

use a pressurized alkaline electrolyzer design with half gaskets and full gaskets between each porous seperator to allow for seperate output per chamber. Remember to note the polarity used as reversing it will alternate the products produced per output line.

[@etanakajp]

12V*50A=600W for only 2LPM (very low production), normally between 180~200W/L

[@senzahydrogen]

Did you make your own unit or buy one? If you did build one, would you be interested in sharing how you did it?

[@CatboyChemicalSociety]

those numbers are wrong because you are forgetting about 50% efficiency so only 300W is used for actual H2 production not 600W. The only way to increase efficiency is to use better electrodes ideally a nickel cathode as it has a lower H2 evolution potential than steel. Alkaline conditions also raise H2 evolution potential which leads to more losses but acidic conditions require exotic electrodes like Ir-Ta as your anode and Pt as your cathode. That setup has greater efficiency than this around 85% instead of 50% but as you can tell its not economically viable. This is why methane steam reforming is still the main way to produce hydrogen though japanese researchers are trying for radiolysis due to the huge excess of energy surplus used. I suggest using nickel plated electrodes in your cell to atleast bump up efficiency by a tiny bit or just put more POWER!!. and use the heat produced in some other process that requires preheating coils.

[@user-tm2nt1rl5m]

@@CatboyChemicalSociety I don't get how could changing the electrodes would boost the efficiency that much, I know that changing it would lower the electrical resistance and element the corrosion. Would It do more than this? Do you have any papers on this topic please?

[@CatboyChemicalSociety]

@@user-tm2nt1rl5m look up Hydrogen evolution potential of different metals and you can see that nickel is nearer to Pt than iron meaning at same voltage it has more current density.

How much gas do we need to run a car ?

[@senzahydrogen]

Firstly, I would not recommend that you use the gas produced by alkaline hydrogen generator for use in your car. This will cause the corrosive alkaline mist to damage the car engine. Secondly the amount of HHO gas going into the car needs to be determined by the displacement and model of your engine. You can refer to this article.senzahydrogen.com/more-hydrogen.html

[@SharhbiniRauf]

With size like that you can easy run your 250cc motorcycle without need gasoline

[@senzahydrogen]

Hydrogen generators require electricity to generate hydrogen. Motorbike gasoline is needed to burn to generate electricity to produce hydrogen. The hydrogen is mixed with petrol to burn it, which effectively increases the burning efficiency of petrol. But you cannot run a motorbike with just a hydrogen generator. Alternatively you can prepare the hydrogen in advance and fill the vehicle with hydrogen bottles. Then use a hydrogen fuel cell to convert the hydrogen into electricity to power the electric vehicle. But the safety of this needs to be further proven.

[@andrealancini3829]

how can i use this to make energy from hydrogen?

[@senzahydrogen]

It's just a device that produces hydrogen. If you need to generate energy from hydrogen, then you need a hydrogen fuel cell. You can check out the video below:kzbin.info/www/bejne/an6xf6GrmNSWY7s and kzbin.info/www/bejne/l3-nnZaZhNF9j6M

[@senzahydrogen]

Energy conversion efficiency with hydrogen fuel cells is roughly 60-80%. Of course you could go for the simpler option and let the hydrogen burn directly to produce heat. Just like with gas.😄
