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 fuel cells, a reactant gas channel, a reactant gas inlet manifold, a reactant gas outlet manifold, an inlet buffer portion, and an outlet buffer portion. A reactant gas flows through the reactant gas channel along a surface of a separator. The reactant gas flows through the reactant gas inlet manifold and the reactant gas outlet manifold in a stacking direction. The inlet buffer portion connects an inlet of the reactant gas channel to the reactant gas inlet manifold. The inlet buffer portion includes linear inlet guide protrusions. Inlet guide channels are provided between the linear inlet guide protrusions and connect the reactant gas inlet manifold to the reactant gas channel. A pitch between the linear inlet guide protrusions increases in accordance with an increase in a distance from the reactant gas inlet manifold to the linear inlet guide protrusions.
