Abstract
A fuel cell stack includes a stacked body which includes separators and a membrane electrode assembly. A first terminal plate, a first insulator, and a first end plate are disposed at a first end of the stacked body. A second terminal plate, a second insulator, and a second end plate are disposed at a second end of the stacked body. Each of the first terminal plate and the second terminal plate is provided in a first recessed portion formed in each of the first insulator and the second insulator. Each of the first and second insulators includes an outer peripheral part and a protrusion and recess portion in the outer peripheral part which is in contact with each of the separators that is disposed at the first and second ends. The protrusion and recess portion has a shape corresponding to a protrusion and recess shape of the separator.
