| 摘要 |
<p>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.</p> |
