    • PROBLEM TO BE SOLVED: To reduce costs for a fuel cell stack.SOLUTION: A gasket 1(2) for a fuel cell is integrally molded by a rubber-like elastic material on an outer periphery of a GDL 3(4) interposed between a separator 6(7) and an MEA 5, and closely contacts the separator 6(7). A gas introduction groove 1b extending so that a manifold hole 1a(2a) opened on the gasket 1(2) and a gas reaction region 10A by the MEA 5 are communicated with each other is formed on a face of the gasket 1(2) opposed to the separator 6(7). The gas introduction groove 1b can be formed at the same time of molding the basket 1(2) by the rubber-like elastic material. There is no need of processing a gas introduction groove on the side of the separator 6(7), and therefore, costs can be reduced.
    • 要解决的问题:降低燃料电池堆的成本。 解决方案:用于燃料电池的垫圈1(2)通过橡胶状弹性材料一体地模制在插入在隔板6(7)和MEA 5之间的GDL 3(4)的外周上,以及 紧密接触分离器6(7)。 在垫圈1(2)的表面上形成有使在密封垫1(2)上开口的歧管孔1a(2a)和MEA5的气体反应区域10A相互连通的气体导入槽1b, 与分离器6(7)相对。 气体引入槽1b可以在橡胶状弹性材料成形篮1(2)的同时形成。 不需要在隔板6(7)侧进行气体导入槽的处理,因此可以降低成本。 版权所有(C)2013,JPO&INPIT

    • PROBLEM TO BE SOLVED: To simply and economically constitute a double seal, and effectively save manufacturing costs.SOLUTION: A cell unit 12 constituting a fuel cell 10 comprises a first electrolyte membrane/electrode structure 14, a first metal separator 16, a second electrolyte membrane/electrode structure 18, and a second metal separator 20. The first and second electrolyte membrane/electrode structures 14, 18 have resin frame members 28a, 28b on their outer peripheries. A double seal 51 provided to the resin frame member 28a has an outer seal member 48 and an inner seal member 50. The tip of the outer seal member 48 contacts the resin frame member 28b, while the tip of the inner seal member 50 contacts an outer peripheral edge of the first metal separator 16. The outer seal member 48 and the inner seal member 50 are set to an identical height dimension.
    • 要解决的问题:简单而经济地构成双重密封,有效节省制造成本。 解决方案:构成燃料电池10的电池单元12包括第一电解质膜/电极结构14,第一金属隔板16,第二电解质膜/电极结构18和第二金属隔板20.第一和第二 电解质膜/电极结构14,18在其外周上具有树脂框架构件28a,28b。 设置在树脂框架构件28a上的双重密封件51具有外部密封构件48和内部密封构件50.外部密封构件48的顶端与树脂框架构件28b接触,同时内部密封构件50的顶端接触 第一金属分离器16的外周缘。外密封构件48和内密封构件50被设定为相同的高度尺寸。 版权所有(C)2013,JPO&INPIT
