Abstract
A fuel cell stack includes: a plurality of power generation cells stacked on top of each other; a dummy cell provided on at least one of both ends of the plurality of power generation cells, the dummy cell being configured not to generate electric power; and a reaction gas supply manifold extending through the plurality of power generation cells and the dummy cell. The dummy cell includes one or more dummy cell reaction gas introduction channels as a reaction gas introduction channel that introduces reaction gas from the reaction gas supply manifold to a center area of the dummy cell. At least one of the dummy cell reaction gas introduction channels is provided so as to connect to a bottom face at a lower side of the reaction gas supply manifold in a direction of gravitational force.
