    • A fuel cell electrode comprising a structure wherein fine particles of a noble metal or a noble metal element-containing alloy are supported on inner walls of fine pores of a porous graphite film having fine continuous pores, a fuel cell electrode having an ion-conducting electrolyte material coated on the inner walls of continuous pores of the electrode, a membrane-electrode assembly (MEA) comprising the fuel cell electrode assembled onto at least one side of the ion-conducting electrolyte material, and a fuel cell comprising the membrane-electrode assembly as a constituent element thereof. It is thereby possible to obtain, by a simple fabrication process, a fuel cell electrode, membrane-electrode assembly and fuel cell having a support structure which allows effective use of noble metal catalysts, which reliably maintains paths for fuel gas, electrons, protons and water, and which consistently exhibits stable performance over extended periods.
    • 一种燃料电池用电极,其具有将贵金属或含有贵金属元素的合金的微粒子负载在具有细小连续孔的多孔石墨膜的细孔的内壁上的结构,具有离子传导电解质的燃料电池电极 涂覆在电极的连续孔的内壁上的材料,包含组装在离子导电电解质材料的至少一侧上的燃料电池电极的膜 - 电极组件(MEA)和包括膜 - 电极组件 作为其构成要素。 因此,可以通过简单的制造方法获得能够有效利用贵金属催化剂的燃料电池电极,膜 - 电极组件和具有支撑结构的燃料电池,所述催化剂可靠地维持燃料气体,电子,质子的路径和 水,长期持续表现稳定。
