摘要： The fuel cell of the invention includes an electrolyte assembly, and a separator having one face as a gas flow path-forming face with a gas flow path formed thereon to allow flow of a reactive gas and the other face, which is reverse to the one face, as a refrigerant flow path-forming face with a refrigerant flow path formed thereon to allow flow of a refrigerant. The gas flow path-forming face of the separator has multiple linear gas flow paths that are arranged in parallel to one another, and a gas flow path connection structure that divides the multiple linear gas flow paths into plural linear gas flow path groups and connects at least part of the plural linear gas flow path groups in series. The refrigerant flow path-forming face has multiple linear refrigerant flow paths that are formed as a reverse structure of the multiple linear gas flow paths on the gas flow path-forming face, and a refrigerant flow path connection structure that is formed as a reverse structure of the gas flow path connection structure on the gas flow path-forming face to connect the multiple linear refrigerant flow paths in parallel.

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.

摘要： An MEA 15 is arranged between frames 13, 14. A first gas flow passage forming member 21 is arranged between an anode electrode layer 17 of the MEA 15 and a first separator 23 fixed to an upper surface of the frame 13. A second gas flow passage forming member 22 is arranged between a cathode electrode layer 18 of the MEA 15 and a second separator 24 fixed to a lower surface of the frame 14. The gas flow passage forming members 21, 22 are each formed by a metal lath 25. The metal lath is formed by forming a plurality of through holes 26 in a thin metal plate in a mesh-like manner and forming the thin metal plate in a stepped shape. The gas flow passage forming members 21, 22 each include a plurality of annular portions 27 forming the through holes 26. Each of the annular portions 27 has a flat surface portion 28a in a first contact portion 28, which contacts a carbon paper 19, 20.

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.
