摘要： A fuel cell stack includes a plurality of power generation cells and a stack case. A tab protrudes from an outer marginal portion of each of the power generation cells. The stack case contains the plurality of power generation cells that are stacked together in a stacking direction, and includes a pair of end plates provided at both ends of the power generation cells in the stacking direction. Further, the fuel cell stack includes a support bar extending inside the stack case in the stacking direction, and including a recess capable of accommodating the tab. One end of the support bar is joined to one of the end plates, and the other end of the support bar is supported by the other of the end plates.

摘要： A fuel cell stack includes a stack body formed by stacking a plurality of power generation cells together in a stacking direction, the power generation cells each having a separator, and a pair of end plates provided at both ends of the stack body in the stacking direction. Further, the fuel cell stack includes a support bar extending between the pair of end plates in the stacking direction and configured to engage with an outer peripheral portion of the separator. The width of the support bar is decreased gradually from one end and the other end toward a central portion in an extension direction in which the support bar extends.

摘要： A fuel cell stack includes a load receiver provided in a first separator, and a contact portion. The load receiver includes a protrusion protruding outward from an outer peripheral portion of the first separator. The protrusion includes a protrusion body positioned at the center in a width direction of the protrusion, and a pair of expansions expanded in the width direction from both ends of the protrusion body in the width direction. When the load receiver contacts the contact portion, only a top portion of the expansion contacts the contact portion.
