摘要： The invention relates to a polymer electrolyte fuel cell comprising a polymer electrolyte film of hydrogen ion conduction; an anode and a cathode between which the electrolyte film is placed; a conductive separator having a channel through which fuel gas is supplied to the anode, and a conductive separator having a channel through which oxidative gas is supplied to the cathode. The conventional conductive separator uses a carbon material that is unlikely to be less costly, and an attempt has been made to use a metal plate in place of the carbon material. Since the metal plate is exposed to an oxidizing atmosphere at high temperature for a long time, however, corrosion may occur, disadvantageously causing the efficiency of power generation to decrease gradually. The polymer electrolyte fuel cell of this invention uses an acid-resistant conductive airtight elastomer as a conductive separator for substantial cost reduction.
摘要翻译：本发明涉及一种包含氢离子传导的聚合物电解质膜的聚合物电解质燃料电池; 阳极和阴极，其间放置电解质膜; 导电隔板，其具有通向该阳极供给燃料气体的通道，以及具有通道的导电隔板，氧化气体通过该通道供给阴极。常规的导电隔离器使用不太可能降低成本的碳材料，并且试图使用金属板代替碳材料。然而，由于金属板长期在高温下暴露于氧化性气氛，所以可能会发生腐蚀，不利地导致发电效率逐渐降低。本发明的高分子电解质型燃料电池使用耐酸性导电性气密弹性体作为导电性隔板，实现大幅降低成本。
