A fuel cell stack includes a plurality of multi-cell modules stacked and a restraining member. Each multi-cell module includes a plurality of fuel cells including opposite end fuel cells at opposite ends of the plurality of fuel cells layered. The restraining member restrains the multi-cell module in a direction perpendicular to the fuel cell stacking direction at the opposite end fuel cells of each multi-cell module. Each of the opposite end fuel cells has an extended portion formed by extending the opposite end fuel cell outwardly in a direction perpendicular to the fuel cell stacking direction, and each multi-cell module is restrained by the restraining member at the extended portion. A hole is formed in the extended portion and a restraining shaft defining the restraining member extends through the hole. A deformation preventing member may be disposed between the extended portions.
