PROBLEM TO BE SOLVED: To suppress bending of an end part cell due to the reaction force of a gasket, in a fuel cell stack.SOLUTION: The fuel cell stack includes a plurality of unit cells stacked with a gasket in between; a terminal which contacts to a surface that dose not adjoin a unit cell among two surfaces of each end part cell arranged at both ends of the plurality of unit cells, with a first thin-wall part provided to a peripheral edge; an insulator which contacts to a surface not contacting to the end part cell among two surfaces of the terminal, with a second thin-wall part provided to a peripheral edge, a first gasket arranged between the end part cell and the unit cell; a second gasket which is arranged to correspond to the first gasket between the end part cell and the first thin-wall part, having a reaction force smaller than the first gasket; and a third gasket which is arranged to correspond to the first gasket and second gasket between the first thin-wall part and the second thin-wall part, having a reaction force smaller than or equal to the reaction force of the first gasket. |
