Abstract
A fuel cell stack comprises a stacked body, an end plate and a case configured such that the stacked body is placed therein. The end plate is arranged to cover an end face of the stacked body in a stacking direction and an end face of the case in the stacking direction and is fastened to the end face of the case. A placement groove is formed in at least one surface out of two surfaces of the end plate and the case opposed to each other, such that a seal member is placed in the placement groove. The end plate includes a resin layer formed to continuously cover an inner circumferential wall surface of the fluid flow path hole, a surface of the end plate opposed to the stacked body, and an outer circumferential side end of the placement groove.
