MEMBRANE-ELECTRODE ASSEMBLY, METHOD FOR PRODUCING THE SAME AND SOLID POLYMER FUEL CELL |
摘要 |
A membrane-electrode assembly (MEA) comprising an anode catalyst layer and cathode catalyst layer placed opposite each other, and a polymer electrolyte membrane formed between the anode catalyst layer and cathode catalyst layer, as well as a fuel cell comprising the same. Either or both the anode catalyst layer and cathode catalyst layer comprise: a catalyst-supported material, having at least one catalyst substance selected from among platinum and platinum-containing alloys and a support on which the catalyst substance is supported; and a hydrocarbon-based polymer electrolyte. The catalyst-supporting ratio of the catalyst-supported material is 60 wt% or greater. |
