摘要： A fuel cell is configured to comprise a power generation layer including an electrolyte membrane, an anode and a cathode, separators and a gas flow path layer provided between the power generation layer and the separator. The gas flow path layer is structured by a plurality of corrugated elements. Each corrugated element has a corrugated cross section where first convexes that are convex toward the separator and second convexes that are convex toward the power generation layer are alternately arranged. The plurality of corrugated elements are arranged, such that a top surface of the first convex in one corrugated element and a bottom surface of the second convex in an adjacent corrugated element cooperatively form an integral surface, and a plurality of through holes are formed between the respective adjacent corrugated elements. The plurality of corrugated elements include a corrugated element having positions of the first convexes and the second convexes shifted in a positive side of the first direction from those of an adjacent corrugated element, and a corrugated element having positions of the first convexes and the second convexes shifted in a negative side of the first direction from those of an adjacent corrugated element. The volume of a first reaction gas flow path, which is formed along the positions of the second convexes on a separator-side of the gas flow path layer, is less than the volume of a second reaction gas flow path, which is formed along the positions of the first convexes on a power generation layer-side of the gas flow path layer.

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 object of the present disclosure is to provide a method for manufacturing a fuel cell that ensures developing a high adhesive strength to a separator. One aspect of an embodiment is a method for manufacturing a fuel cell where a pair of separators are mutually bonded with a sealing member. The sealing member includes a thermoplastic resin containing a crystalline polymer as an adhesive layer. The method for manufacturing the fuel cell includes: preparing a stack structure in which the sealing member is disposed between the pair of separators; heating the stack structure at a melting point or higher of the thermoplastic resin; after the heating, holding the stack structure in a temperature range of ±10°C of a crystallization temperature of the thermoplastic resin to promote a crystallization of the thermoplastic resin; and after the holding, further cooling the stack structure.
