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.

An improved method of operating a hydrogen/halogen fuel cell comprising a. introducing hydrogen fuel into the anode chamber of a fuel cell; b. introducing a halogen oxidant into the cathode chamber of a fuel cell; c. contacting said hydrogen fuel with the catalytic anode thereby catalytically disassociating the hydrogen into hydrogen ions and electrons; d. transporting the hydrogen ions through a solid polymer electrolyte membrane to the cathode electrode; e. passing the electrons through an external circuit to the cathode; f. reacting the oxidant with the hydrogen ions in the presence of the catalytic cathode to produce an acid; wherein the improvement comprises humidifying the hydrogen gas prior to its introduction into the anode chamber thereby providing excess water which maybe protonically pumped through the solid polymer electrolyte membrane with the hydrogen ions to the cathode and thereby diluting the acid produced at the cathode.
