Abstract:
1. A fuel cell stack comprising: a plurality of cells stacked, each of the plurality of cells including an anode and a cathode and being formed in a plate shape; a fuel gas discharging manifold which extends in a thickness direction and through which an anode off gas unconsumed in the anode flows, the thickness direction being a direction perpendicular to a plane created by the anode and the cathode; an oxidizing gas discharging manifold which extends in the thickness direction and through which a cathode off gas unconsumed in the cathode flows; and a cooling medium discharging manifold which extends in the thickness direction and through which an off cooling medium having recovered heat from the plurality of cells flows, wherein: at least one of the fuel gas discharging manifold and the oxidizing gas discharging manifold forms a concave portion when viewed from the thickness direction, at least a part of the at least one of the cathode gas discharging manifold and the anode gas discharging manifold which forms the concave portion is disposed between the cooling medium discharging manifold and a separator end closest to the cooling medium discharging manifold, when viewed from the thickness direction, and the cooling medium discharging manifold is disposed such that at least a part of the cooling medium discharging manifold fits in the concave portion when viewed from the thickness direction.
