    • An electrolyte membrane characterized by comprising a porous body formed from a melt-moldable fluororesin and having interconnected pores and an ion exchange resin with which the interconnected pores are filled, is provided. Specifically, the porous body is formed, for example, from an ethylene/tetrafluoroethylene copolymer, a tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer, a tetrafluoroethylene/hexafluoropropylene copolymer, a tetrafluoroethylene/[CF2═CF—(OCF2CFY)a—Oc—(CF2)b—SO3H] copolymer (wherein Y is a fluorine atom or a trifluoromethyl group, a is an integer of 0 to 3, b is an integer of from 0 to 12, and c is 0 or 1, provided that when b=0, C=0), or the like. An electrolyte membrane reinforced by such a porous body has high mechanical strength even if it is thin, and is excellent in dimensional stability when hydrated, and a polymer electrolyte fuel cell with a membrane-electrode assembly having the electrolyte membrane provides a high output and is excellent in durability.
    • 一种电解质膜,其特征在于,包括由可熔融成型的氟树脂形成并具有互连孔的多孔体和填充有互连孔的离子交换树脂。 具体地说,多孔体例如由乙烯/四氟乙烯共聚物,四氟乙烯/全氟(烷基乙烯基醚)共聚物,四氟乙烯/六氟丙烯共聚物,四氟乙烯/ [CF 2 = CF-(OCF 2 CFY)a-Oc- (CF 2)b -SO 3 H]共聚物(其中Y为氟原子或三氟甲基,a为0〜3的整数,b为0〜12的整数,c为0或1,条件是当b = 0,C = 0)等。 由这样的多孔体增强的电解质膜即使较薄也具有高的机械强度,水合时的尺寸稳定性优异,具有电解质膜的膜电极组件的固体高分子型燃料电池提供高输出量 耐用性好。
