A fuel cell stack includes at least two cell modules adjacent to each other, the at least two cell modules each being formed by stacking a plurality of fuel cells into an integrated unit and a seal plate interposed in a cooling flow channel defined between separators of the at least two cell modules, the cooling flow channel configured to allow a cooling fluid to flow therethrough. The seal plate includes a manifold portion in which a plurality of manifold holes are formed to allow two power-generation gases to flow separately through the plurality of manifold holes and through the plurality of fuel cells and a seal member provided along a peripheral portion of each of the plurality of manifold holes to provide sealing for a corresponding one of the two power-generation gases flowing through the manifold hole.
