    • Oxidation or corrosion of carbon material contained in a cathode due to the reverse current that occurs at the starting of a fuel cell is suppressed. The fuel cell includes a plate-like cell, a separator on one side of the plate-like cell, and a separator on the other side of the plate-like cell. The plate-like cell includes a solid polymer electrolyte membrane, an anode, and a cathode. The anode has a stacked body composed of a catalyst layer and a gas diffusion layer. The cathode has a stacked body composed of a catalyst layer and a gas diffusion layer. The catalyst layer contains a porous carbon material formed with micro pores, which functions as an electric double layer, and an ion-exchange resin. At least part of the porous carbon material supports a catalytic metal such as platinum. The porous carbon material to be used is preferably a carbide-derived carbon. The carbide-derived carbon preferably has micro pores of 1 nm or less.
    • 由于在燃料电池起动时发生的反向电流,阴极中包含的碳材料的氧化或腐蚀被抑制。 燃料电池包括板状电池,板状电池一侧的隔板和板状电池另一侧的隔板。 板状电池包括固体聚合物电解质膜,阳极和阴极。 阳极具有由催化剂层和气体扩散层组成的层叠体。 阴极具有由催化剂层和气体扩散层构成的层叠体。 催化剂层含有形成有作为双电层的微孔的多孔碳材料和离子交换树脂。 至少部分多孔碳材料支持催化金属如铂。 所使用的多孔碳材料优选为碳化物衍生的碳。 碳化物衍生的碳优选具有1nm以下的微孔。
