    摘要： A gas channel forming plate includes protrusions, which extend parallel with each other, gas channels that are respectively located between each adjacent pair of the protrusions, and water channels, which are respectively formed on the back surface of each protrusion. Each protrusion includes first communication portions and second communication portions. Each first communication portion includes a first opening. Each second communication portion includes a second opening. The second communication portions of each protrusion constitute an expanding region, in which the opening area of the second opening in each second communication portion is greater than the opening area of the first opening of each first communication portion, to limit introduction of water to the water channel on the back side of the protrusion using capillary action by the second communication portions.

    摘要： A gas flow passage-forming member (10) is disposed between a membrane electrode and gas diffusion layer assembly (12) and a separator (13) of a fuel cell, and the gas flow passage-forming member (10) is configured to form a gas flow passage (Ar). The gas flow passage-forming member (10) has a corrugated shape such that groove portions (31, 33) and ridge portions (32, 34) are provided on each of a front side and a back side of the gas flow passage-forming member (10). The groove portions (31) each serve as the gas flow passage (Ar). The gas flow passage-forming member (10) has communication holes (41) providing communication between the front side and the back side, and the communication holes (41) are provided in a region downstream of an upstream region (30A) in a gas flow direction. The upstream region (30A) is a non-communication region with no communication hole (41).

    摘要： A fuel cell is formed by laminating a plurality of power generating units. The power generating unit includes: a membrane electrode gas diffusion layer assembly; a sealing portion disposed along its outer circumference; a porous body flow path in which oxidant gas supplied to a cathode-side catalytic layer flows; a shielding plate provided between the sealing portion and the porous body flow path; and first, second separator plates configured to sandwich the membrane electrode gas diffusion layer assembly and the porous body flow path therebetween. The shielding plate, the porous body flow path, and the first separator plate making contact with the porous body flow path project into the oxidant exhaust gas discharge manifold determined by the sealing portion.
