A sulfonic acid polymer is processed so that it can be used as a proton conducting membrane for a fuel cell. Asymmetric properties are formed. The preferred fuel cell assembly includes an anode which is a porous carbon electrode including carbon/catalyst particles coated with the processed sulfonic acid polymer. The anode current collector (202) includes carbon paper fiber impregnated with the processed sulfuric acid polymer. Proton conducting membrane (204) adjoins the cathode (206). The proton conducting membrane includes a dense surface of proton conducting membrane (206) facing the anode (200). The surface (208) facing the cathode (210) is preferably a very thin layer of cross-linked low proton conducting surface.

On traite un polymère d'acide sulfonique pour pouvoir l'utiliser en tant que membrane conductrice de protons dans une pile à combustible. On obtient ainsi des propriétés asymétriques. L'ensemble pile à combustible préféré comporte une anode qui est une anode en carbone poreux comprenant des particules de carbone-catalyseur revêtues dudit polymère d'acide sulfonique traité. Le collecteur de courant anodique (202) comporte de la fibre de papier carbone imprégnée dudit polymère. La membrane conductrice de protons (204) est contiguë à la cathode (206). La membrane conductrice de protons (206) comporte une surface dense en regard de l'anode (200). La surface (208) faisant face à la cathode (210) est, de préférence, une couche très mince à surface réticulée et faiblement conductrice de protons.
