摘要： An electrode structure 15 is received in a joint portion of frames 13, 14. A first gas diffusion layer 19 and a first gas passage forming member 21 are arranged on a first surface of the electrode structure 15. A second gas diffusion layer 20 and a second gas passage forming member 22 are formed on a second surface of the electrode structure 15. A separator 23 is joined with a surface of the frame 13 and a surface of the gas passage forming member 21. A separator 24 is joined with a surface of the frame 14 and a surface of the gas passage forming member 22. A water passage 28 is formed between a flat plate 25 of the gas passage forming member 22 and the separator 24. The water passage 28 has a depth set to a value smaller than depth of a gas passage T2 of the gas passage forming member 22. Generated water is introduced from the gas passage T2 of the gas passage forming member 22 to the water passage 28 through capillary action via communication holes 29. The generated water in the water passage 28 is moved to a downstream side of the water passage 28 by pressure caused by oxidization gas. This prevents corrosion of the cathode side electrode catalyst layer and improves durability of the anode side gas passage forming member. As a result, a fuel cell capable of preventing decrease of power generation is provided.

摘要： In a fuel cell having a cell structure in which a gas flow passage is formed by an expanded metal, a bond portion connecting a mesh of the expanded metal stands partially upright in a position where a bond length is shortened so as to form a part of a strand portion. Hence, in an opening formed by the mesh of the expanded metal, a surface area on which front and rear openings overlap in a direction increases when seen from an direction. Thus, a sectional area of gas flow passages constituted by a continuum in the direction of the openings overlapping in the direction increases. As a result, a gas flow flows without making repeated narrow turns, leading to a reduction in gas pressure loss.

摘要： There is realized a structure particularly suitable for inhibiting deformation of separators having a structure where the shapes of projections and recesses are inverted from each other on the front side and the back side of each separator as in a pressed metal separator. Between adjacent separators, there is formed either a power generation region where MEAs and frame members for holding at least a part of the MEAs are inserted or a refrigerant flow region where neither the MEAs nor the frame members are inserted. A deformation inhibiting region for inhibiting deformation of each separator is formed by a projection provided on the separator. Also, a projection for inhibiting the separator from deforming at the deformation inhibiting region or nearby is formed on each frame member. The projection is projected toward the back side of the deformation inhibiting region, where the deformation inhibiting region is a recess on the back side of the separator.
