ABSTRACT:
The present invention discloses an improved method for operating a conventional solid polymer electrolyte membrane hydrogen/halogen fuel cell. The improvement comprises humidifying the hydrogen gas prior to it entering the anode chamber thereby providing additional water to be protonically pumped through the membrane to the cathode where it dilutes the acid produced by the cathodic reaction.
