Abstract
A fuel cell includes; a membrane electrode gas diffusion layer assembly, first and second separators sandwiching the membrane electrode gas diffusion layer assembly; a sealing member having a resin-made base material, a first adhesive layer bonding one surface of the base material to the first separator, and a second adhesive layer bonding the other surface of the base material to the second separator; and an adhering portion bonding an inner periphery of the one surface of the base material to the periphery of the electrolyte membrane. The first and second adhesive layers are separated from the adhering portion, no other adhesive component than an adhering portion is provided in the base material between the inner periphery of the base material and the first and second adhesive layers, and a linear expansion coefficient of the base material is smaller than any of those of the first and second adhesive layers.
