Hydrogen Fuel Cell Porous anode and cathode? Answered
I found this image that details a hydrogen fuel cell (reverse electrolysis). Does anyone know what materials are good for the porous anode and cathode? Is carbon porous on a molecular scale? I want to make a simple reverse electrolysis in order to use hydrogen power. I would appreciate any help.
