Abstract:
1. A fuel cell stack formed by stacking a membrane electrode assembly and separators in a stacking direction, the membrane electrode assembly including a pair of electrodes and an electrolyte membrane interposed between the electrodes, the fuel cell stack including rectangular end plates provided at opposite ends in the stacking direction, wherein the end plate has opposed surfaces forming land surfaces, wherein passages that function at least as fluid supply passages or fluid discharge passages for a coolant or a reactant gas are formed along the end plates in a longitudinal direction, and extend through the fuel cell stack, the passages being formed within the land surfaces, the fuel cell stack comprising: a resin manifold member connected to any of the passages, and extending along a land surface of one of the end plates in the longitudinal direction; a reinforcement member provided on at least one end of the resin manifold member in the longitudinal direction, for preventing the resin manifold member from peeling off from the end plate; and a connector having first and second opposed surfaces, wherein substantially the entire first surface of said connector is disposed in intimate facing contact with the opposed land surface of said one of the end plates, the reinforcement member being connected to the connector and the resin manifold member.
