    摘要： Bead seal structure includes an outer bead (bead seal) for preventing leakage of fluid, and a first bypass stop protrusion (intersecting element) which intersects with the outer bead. The first bypass stop protrusion includes a root as a rising start point from a base plate and side walls which rise from the base plate. The radius of curvature of connection parts of the roots connected to the outer bead is larger than the radius of curvature of connection parts of the side walls connected to the outer bead.

    摘要： A fuel cell includes a membrane electrode assembly and a separator. The separator includes a water accumulation portion including at least one of a buffer portion, a lowermost channel groove, a channel junction portion, and a bypass channel. The buffer portion is connected to a reactant gas channel through which a reactant gas is to flow along a power generation surface of the membrane electrode assembly. The channel groove is provided in the reactant gas channel and located at a lowest position in the reactant gas channel in a direction of gravity when the membrane electrode assembly and the separator are in an upright position. Channel grooves of the reactant gas channel are joined in the channel junction portion. The membrane electrode assembly includes a water impermeable layer which is disposed outside of a power generation region and which faces the water accumulation portion.

    摘要： Provided is a fuel cell including a plurality of stacked unit cells, each including a membrane-electrode assembly and a separator stacked on the membrane-electrode assembly. The separator includes a separator plate that overlaps the membrane-electrode assembly when seen from a stacking direction, a first terminal portion configured to protrude from the separator plate toward an outer side in a plane direction, a plate covering portion configured to cover an outer peripheral edge of the separator plate, and a terminal covering portion configured to be formed integrally with the plate covering portion and covers the first terminal portion. A plurality of the first terminal portions, which are adjacent to each other in the stacking direction, include offset portions which shift from each other when seen from the stacking direction, and are covered with the terminal covering portion.

    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 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.
