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.

A pair of passage groove groups connected to the recessed portion of the flow merge region (22) is formed so as to have a greater number of grooves in the upstream passage groove group than the number of grooves of grooves in the downstream passage groove group. The recessed portion of the flow merge region (22) is defined, in a turn portion of a serpentine shaped reaction gas passage region (101), by oblique boundaries between the recessed portion and a pair of passage groove groups which are connected to the recessed portion and by the outer end of the turn portion.
