摘要： In at least one of flow distribution areas 35 provided on a separator 15, plurality of first projections 46 formed in a region corresponding to a first section (parted regions 32a and 32c) of a center area (including parted regions 32a through 32c) having a relatively high flow rate of a first fluid (refrigerant) are designed to have a larger diameter of a cross section than plurality of first projections 46 formed in a region corresponding to a second section (parted region 32b) of the center area having a relatively low flow rate of the first fluid. This arrangement effectively attains a substantially uniform flow rate distribution of a fluid in a fluid flow path formed on a separator, which is configured to have concavo-convex structures formed in a mutually reversed relation on two opposed sides thereof.

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： 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： Miniaturization is achieved when a membrane-electrode assembly (MEA) is provided with a cutout, and the flow of a fluid is further smoothened. To realize this, in a separator for a fuel cell according to the present invention, a portion of the contour of a manifold formed in the separator corresponding to a cutout of the membrane-electrode assembly is formed into a shape along the cutout, and a reactant gas or a coolant is supplied or discharged through a portion formed into the shape along the cutout. The cutout is, for example, a corner cut provided in the corner of the membrane-electrode assembly and forming the membrane-electrode assembly into an asymmetric shape. A portion of the contour of the manifold facing this corner cut is preferably formed substantially in parallel with the edge of the corner cut.
