Abstract

A proton exchange membrane fuel cell and method for forming a fuel cell is disclosed and which includes, in its broadest aspect, a proton exchange membrane having opposite anode and cathode sides; and individual electrodes juxtaposed relative to each of the anode and cathode sides, and wherein at least one of the electrodes is fabricated, at least in part, of a porous, electrically conductive ceramic material. The present methodology, as disclosed, includes the steps of providing a pair of electrically conductive ceramic substrates, applying a catalyst coating to the inside facing surface thereof; and providing a polymeric proton exchange membrane, and positioning the polymeric proton membrane therebetween, and in ohmic electrical contact relative thereto to form a resulting PEM fuel cell.
