|In a fuel cell gases flow into porous chambers impregnated with cataylsts. These gas chambers are immersed in a KOH or NaOH solution.|
|Anode reaction: H2 + 2 OH-1 ----> 2 H2O + 2 e-1|
|Cathode reaction: O2 + 2 H2O + 4 e-1 -----> 4 OH-1|
|The reaction requires a continuous flow of H2
at 250oC and 5000 kPa pressure.
