A polymer electrolyte fuel cell having a large economical advantage uses a gasket which includes an elastomer layer that is inexpensive, highly resistant to chemicals, particularly to acids, and exhibits a high sealability. The elastomer layer is provided with an adhesive layer, and the gasket is both easy to position and easy to assemble. The fuel cell includes unit cells each including a positive electrode, an electrolyte plate, and a negative electrode, and gaskets each arranged at the circumferential part of the unit cell alternately stacked via a separator placed therebetween. The gasket includes an elastomer layer and an adhesive layer, with the elastomer layer being adhered to at least one side of the separator via the adhesive layer.
