摘要：
本发明的目的在于进一步改善具有使用烃系高分子电解质的高分子电解质膜的燃料电池的发电特性。本发明提供具有相向配置的阳极催化剂层及阴极催化剂层，和设置在阳极催化剂层与阴极催化剂层之间的高分子电解质膜的膜-电极接合体。高分子电解质膜含有烃系高分子电解质，阳极催化剂层和阴极催化剂层包含具有选自铂和含铂的合金中的至少1种催化剂物质和负载该催化剂物质的载体的催化剂载体、和高分子电解质，阳极催化剂层和阴极催化剂层中的至少一方中的催化剂载体的催化剂负载率为60质量％以上。
摘要（英）：

The present invention aims to improve power generation characteristics of a fuel cell which comprises a polymer electrolyte membrane using a hydrocarbon polymer electrolyte. Specifically disclosed isa membrane-electrode assembly comprising an anode catalyst layer and a cathode catalyst layer arranged opposite to each other, and a polymer electrolyte membrane arranged between the anode catalyst layer and the cathode catalyst layer. The polymer electrolyte membrane contains a hydrocarbon polymer electrolyte, and the anode catalyst layer and the cathode catalyst layer respectively contain a polymer electrolyte and a catalyst loaded body which is composed of at least one catalyst substance selected from platinum and alloys containing platinum, and a carrier supporting the catalyst substance.The catalyst loading ratio of the catalyst loaded body in at least one of the anode catalyst layer and the cathode catalyst layer is not less than 60% by mass.
