FUEL CELL STACK

PROBLEM TO BE SOLVED: To provide a fuel cell stack capable of increasing the stability of the power output by preventing water droplet from directly reaching a gas flow path inlet of a manifold to prevent a gas flow path from being clogged by water droplet.SOLUTION: The fuel cell stack includes: an electrolyte membrane-electrode assembly which has a solid polymer electrolyte membrane and a gas diffusion electrode; and a separator which has gas flow path grooves for supplying gas to the gas diffusion electrode. The fuel cell stack includes: a manifold for supplying the gas to the gas flow path; and a gas supply member which has a cylindrical gas supply port for supplying the gas to the manifold. The gas supply port of the gas supply member is provided vertically above the inlet of the gas flow path, and a plate-like shield member is disposed between the gas supply port and the inlet of the gas flow path as viewed from a thickness direction of the separator, extending from the gas supply port toward the manifold.
