摘要： A fuel cell stack at least includes a first dummy cell provided at one end of a stack body formed by stacking a plurality of power generation cells in a stacking direction. A dummy assembly of the first dummy cell includes a first electrically conductive porous body, a second electrically conductive porous body, and a third electrically conductive porous body, which are stacked in this order. A first joint layer is interposed between the first electrically conductive porous body and the second electrically conductive porous body to join the first and second electrically conductive porous bodies together, and a second joint layer is interposed between the second electrically conductive porous body and the third electrically conductive porous body to join the second and third electrically conductive porous bodies together. The first joint layer and the second joint layer are provided at different positions in the stacking direction.

摘要： A fuel cell stack at least includes a stack body formed by stacking a plurality of power generation cells in a stacking direction and a first dummy cell provided at one end of the stack body in the stacking direction. The power generation cell includes a membrane electrode assembly. The first dummy cell includes a dummy assembly formed by stacking together three electrically conductive porous bodies each having a different surface size, a dummy resin frame member formed around the dummy assembly, and dummy separators.

摘要： A thermosetting adhesive sheet 10 for sealing the periphery of a membrane electrode assembly, which is composed of a solid polymer electrolyte membrane and electrodes placed on both sides of the solid polymer electrolyte membrane contains an adhesive layer 14. The adhesive layer 14 is formed of a cured product of an adhesive composition containing a polyurethane resin having a reactive functional group and a cross-linking agent, where the adhesive layer 14 has a gel fraction of 60 mass % or higher, a storage elastic modulus at 100° C. (G′100) of 5.0×104 Pa or higher and 1.0×108 Pa or lower, and a decreasing rate of a storage elastic modulus at 120° C. (G′120) to the storage elastic modulus at 100° C. (G′100) of 0.5 or less.

摘要： A method for manufacturing a carbon fiber sheet, the method including a carbon fiber forming step of heating a resin sheet to a carbonization temperature at a heating rate of 15,000° C./sec or higher, thereby forming a carbon fiber from the resin sheet. In the carbon fiber forming step, the resin sheet is preferably irradiated with an energy ray having an output density of 130 W/mm2 or higher and an amount of irradiation energy of 0.05 J/mm2 or more.

摘要： A power generation cell includes a resin-framed electrolyte membrane electrode assembly. The cathode of the resin-framed membrane electrode assembly has a larger surface dimension than the anode. An outer peripheral portion of the anode is positioned between a first buffer and a fuel gas flow field. An outer peripheral portion of the cathode is positioned between the resin frame member and the second buffer.
