Abstract: A fuel cell separator includes a separator body and porous structure. The porous structure is stacked on a body surface with pores therein to provide a fluid flow path. The body includes: an inlet part having a space into which the fluid is introduced, a reaction region receiving the fluid, and a diffusion part between the inlet part and the reaction region and a passage to provide a path supplying fluid within the inlet part to the reaction region. The porous structure is stacked on a reaction region surface. A first inlet region, provided at the same height as the inlet part in a height direction in a porous structure inlet region facing the diffusion part, is provided closer to a central region of the porous structure than a second inlet region except for the first inlet region in the inlet region of the porous structure facing the diffusion part.

Abstract: A separator for a fuel cell allows air to bypass a diffusion part, which is frequently exposed to air, and thus flow directly to a reaction surface, which can reduce deterioration of a polymer electrolyte membrane. The separator includes a separator main body having a diffusion part formed thereon that is configured to allow air to be diffused and supplied from an air inlet manifold to the reaction surface; and a gasket line formed on the separator main body and surrounding the air inlet manifold and the reaction surface to maintain airtightness. The separator main body or the gasket line includes a bypass flow path formed thereon so as to allow air supplied from the air inlet manifold to flow directly to the reaction surface without passing through the diffusion part.

Abstract: A separator for a fuel cell and a method for manufacturing the same comprise two sheets of metal plates integrally formed to minimize contact resistance between an upper metal plate and a lower metal plate. The method for manufacturing the separator includes steps of preparing an upper metal plate and a lower metal plate, each plate having opposing main sides, and applying a coating liquid containing a polymer composite material on both sides of the upper and lower metal plates, to form first and second composite material layers on both sides of the upper plates and third and fourth composite material layers on both sides of the lower plates. The method further includes stacking the upper metal plate on the lower metal plate, before drying the respective composite material layers, and integrally bonding the second composite material layer and the third composite material layer to form a single intermediate composite material layer.
