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.

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： A fuel cell includes a separator including a first member made from metal and a second member made from synthetic resin. The separator has a power generating portion corresponding portion including a gas passage portion and opposing portions located on opposite sides of the power generating portion corresponding portion. A manifold portion is formed in the opposing portions. The manifold portion is offset from the gas passage portion. A gas passage connecting portion is formed in the second member and fluidly connects the manifold portion and the gas passage portion. A gas flow adjusting portion is formed for directing a direction of a gas flow at the gas passage connecting portion to a direction perpendicular to a direction connecting the opposing portions and making a gas flow into and from the gas passage portion uniform in the direction perpendicular to a direction connecting the opposing portions.
