Claim:
1. A fuel cell stack comprising: a stack body in which a plurality of unit cells is stacked; a case for accommodating the stack body; and an external restriction member that restricts misalignment between the plurality of unit cells in a second direction perpendicular to a first direction in which the plurality of unit cells is stacked, wherein the external restriction member includes: corner restriction members provided in the case so as to extend entirely over at least two corners of the stack body along the first direction; and a rotation suppressing member provided in the case so as to face one side surface of the stack body, the side surface being positioned so as to intersect with a direction in which the stack body may rotate about the corner restriction members as rotation axes when an impact force along the second direction is applied to the stack body from outside, and wherein the rotation suppressing member is provided in an area that does not contain corners of the stack body.
