The fuel cell stack according to one aspect of the present invention has a plurality of manifolds passing through a plurality of fuel cells in the stacking direction, and circulating a fuel gas or an oxidant gas. As the manifolds, the stack has cold gas manifolds for introducing the fuel gas or the oxidant gas into the fuel cell stack from the outside, hot gas manifolds for discharging the fuel gas or the oxidant gas from the fuel cells, and heat-exchanged gas manifolds for circulating heat-exchanged gas having undergone heat exchange in a heat exchange unit. Further, the cold gas manifolds are adjacent to the hot gas manifolds, and the hot gas manifolds are not adjacent to other hot gas manifolds. |
