摘要： In a fuel cell composed of a pair of separators with a membrane electrode assembly sandwiched therebetween, gas passages having a plurality of generally linear passage portions, and bent passage portions each of which makes one end portion of the linear passage portions communicated with the other end portion of the linear passage portions, are formed so as to be communicative from a gas introducing port to a discharge port. In inner wall surfaces of the groove portions of the separators constituting the linear passage portions, water-retaining groove portions capable of retaining inside thereof at least part of water generated in the gas passage are formed in such a grooved configuration as to be substantially continuous along the passage portion. As a water drop generated within the gas passage makes contact with retained water within the water-retaining groove portions, growth of the water drop is suppressed to avoid any blockage of the gas passage, by which the anti-flooding property is improved.

摘要： A MEA-frame assembly is arranged in a mold for injection molding to form a first flow passage arranged so as to extend along the outer periphery of an electrode between the outer periphery of the electrode and the inner periphery of a frame, a second flow passage arranged so as to extend along an inner elastic member between the inner periphery and outer periphery of the frame and a plurality of connecting flow passages which communicate the first flow passage with the second flow passage. An elastic resin is injected into the first flow passage to fill the first flow passage with the elastic resin and to fill the second flow passage with the elastic resin through each of the communicating flow passages, thereby an elastic member which hermetically seals the space between the MEA-frame assembly and the separator is integrally formed.
