摘要： A fuel cell includes a membrane electrode assembly, a separator, and a sealing member. The sealing member is provided on a separator surface and includes a base seal portion, a protruding seal portion, a first recessed portion, and a second recessed portion. The protruding seal portion protrudes from the base seal portion in a stacking direction so as to block leakage of at least one of a fuel gas, an oxidant gas, and a coolant which flow along the separator surface. The first recessed portion is disposed on a first side of the protruding seal portion. The second recessed portion is disposed on a second side of the protruding seal portion opposite to the first recessed portion. The first recessed portion and the second recessed portion have a height in the stacking direction smaller than a height of the base seal portion in the stacking direction.

摘要： A fuel cell stack includes a first power generation unit and a second power generation unit. Wave-like first fuel gas flow passages of the first power generation unit and wave-like first fuel gas flow passages of the second power generation unit are set to mutually different phases. The ends of the first fuel gas flow passages form linear flow passage grooves that linearly extend in the wavelength direction from the center of the width of the wave-form amplitude.

摘要： A fuel cell includes an electrolyte-electrode assembly, a frame member, a first separator, and a second separator. The frame member is provided to face a first surface of the second separator and includes a resin wall which forms a periphery of a first reactant gas passage. The resin wall has a thin-walled portion which overlaps with a cooling medium connecting portion in a stacking direction and which protrudes toward the first reactant gas passage in the stacking direction by a first dimension from a surface of the frame member. Another portion of the resin wall protrudes toward the second separator in the stacking direction by a second dimension from the surface of the frame member. The first dimension is smaller than the second dimension.
