Abstract
A fuel cell stack includes a stack; a case that accommodates the stack; and end plates arranged in the outside of a stacking direction and formed with fluid flow path holes penetrating in the stacking direction an accommodating groove for accommodating a seal member for sealing a part between the accommodating groove and the case. The end plates have a metal member formed with the fluid flow path holes, a first recess and a second recess that continues to the first recess, and a resin layer that continuously covers an inner peripheral wall surface of the fluid flow path holes, a surface that faces the stack, a part that includes at least an outer peripheral side end in the first recess, and the second recess, in the metal member. The resin layer is formed with the accommodating groove in a surface corresponding to the end surface of the case in a part covering the part that includes at least the outer peripheral side end in the first recess. The second recess accommodates a part of the resin layer to restrict the resin layer.
