The discussion revolves around building a hydrogen generator using stainless steel plates and the necessary apparatus for electrolysis. Participants explore various aspects of the design, materials, and potential sources for equipment and components, while also addressing safety concerns and operational considerations.
Participants express a range of views on the design and materials for the hydrogen generator, with no clear consensus on the best approach or the feasibility of certain methods. Disagreements exist regarding the role of stainless steel and the specifics of electrolysis.
Participants mention various assumptions about the efficiency of materials and the electrical requirements for hydrogen production, but these remain unresolved. The discussion includes references to safety concerns and operational experiences that may not be universally applicable.
This discussion may be of interest to hobbyists and researchers exploring electrolysis, hydrogen generation, and related experimental setups in the context of renewable energy and automotive applications.
RNickl said:Ouch: Bit of egg on my face. Just realized what forum this was posted too and what you may be trying to do. You need a much better grasp on this subject before you waste money, or even bother to design, your generator.
deuel18 said:Great though :D .Btw I'm planning to make a Hydrogen generator that's why I need to work on meta works. Is there some hardware shops around Sj that could help out though?
Four hundred amps?! You might want to rethink your time frame.deuel18 said:2.8 liters in less than a minute
It depends upon how many electrons you have to pass to hydrolyze 0.1 to 0.15 mol water in a minute or a little less.deuel18 said:I believe it depends on the configuration of the generator like the surface area of the plate, its size, how good the catalyst is,
deuel18 said:Its not that expensive to make a hydrogen generator. The only problem is the proper shape and size of the stainless steel plate. Thats all.
deuel18 said:Stainless Steel Plate will act as the Hydrogen Fuel Cell generator while submerged in water.
berkeman said:Stainless steel as a catalyst? I'm no chemist, but that sounds like an oxymoron...

A very "exciting" and effective one for some reactions that shall remain unidentified. Works for electrolysis. Lousy as a fuel cell electrode.berkeman said:Stainless steel as a catalyst?
Doug Huffman said:I have been near electrolytic oxygen/hydrogen generators, though never responsible for their operation or maintenance. Submarine sailors become inured to lots of the alarms on their ships, like salinity alarms and temperature alarms. But not the oxygen generator alarm or the anti-submarine alarms.
The O2 generator was nicknamed The Bomb for the potentially hazardous effects of 3000 psi gasses and high electrical currents. My particular vessel carried five-thousand chlorate candles. Once a danger tag was violated and they were wetted with seawater and each one had to be rinsed and dried and restowed, it took about a week.
Yes, just so. The H2 discharge is to an auxiliary cooling seawater, though notably the actual piping penetration is IIRC after the ASW hull and backup valves for the corrosive effects of HCl - the gaseous discharge had its own hull and backup valves.deuel18 said:Interesting. What happens to the H2 after the electrolysis? Is it dumped back to the seawater?
deuel18 said:Considering a car engine, maybe about 2.8 liters in less than a minute (rough estimate). And glassware can't do the job. The container can be glassware but the Stainless Steel Plate will act as the Hydrogen Fuel Cell generator while submerged in water.

There is also a high temperature catalyst burner intended to burn atmospheric CO and H2 (as from the huge Pb-acid battery) to CO2 and H2O.
