Abstract
A fuel cell stack according to one aspect of the present invention has a plurality of fuel cells stacked together and a plurality of manifolds passing through the fuel cells in a stacking direction thereof so as to allow at least one of the fuel gas and the oxidant gas to flow therethrough. The manifolds include cold gas manifolds adapted to introduce the fuel gas or oxidant gas from the outside into the fuel cell stack, hot gas manifolds adapted to discharge the fuel gas or oxidant gas from the fuel cells, and a heat-exchanged gas manifold adapted to feed the fuel gas or oxidant gas that has been heat-exchanged in a heat exchange part. Every one of the cold gas manifolds is adjacent to any of the hot gas manifolds. One of the hot gas manifolds is non-adjacent to any other one of the hot gas manifolds.
