摘要：
A polymer electrolyte fuel cell includes: a sealing structure (9) including a substantially rectangular ring-shaped first gasket portion (9a) and a substantially rectangular ring-shaped second gasket portion (9b), the first gasket portion (9a) being positioned outward of a peripheral portion of a first gas diffusion layer (5) and between a first separator (7) and a first catalyst layer (2) positioned at a peripheral portion of a polymer electrolyte membrane 1, the second gasket portion (9b) being positioned outward of the peripheral portion of the polymer electrolyte membrane (1) and between the first separator (7) and a second separator (8); and at least the first catalyst layer (2), a second catalyst layer (3), and a swellable resin portion (II) formed of a swellable resin whose volume expands when water is added thereto, the swellable resin portion (11) being positioned between the first gasket portion (9a) and the first catalyst layer (2) positioned at the peripheral portion of the polymer electrolyte membrane (1).
