Abstract:
1. A fuel cell gas diffusion layer integrated gasket comprising: a first gas diffusion layer; a first gasket which is integrally formed in the peripheral edge of the first gas diffusion layer; a second gas diffusion layer; a second gasket which is integrally formed in the peripheral edge of the second gas diffusion layer; and a hinge portion which connects the first gasket and the second gasket to each other, wherein the first gas diffusion layer and the second gas diffusion layer sandwich a film-electrode complex body having catalyst electrode layers formed on both surfaces of an electrolyte film from both sides, and wherein a close contact surface of the first gasket is provided with a seal protrusion which is compressed directly against the film electrode complex body and an entirety of a close contact surface of the second gasket which is compressed directly against the film-electrode complex body opposing the seal protrusion, is planar in an uninstalled condition.
