Abstract: A separator assembly for an air-cooled fuel cell includes: a cathode separator and an anode separator, each of which having a cooling surface bonded to each other to face each other. The separator assembly further includes a plurality of first gaskets having a ring shape configured to surround and seal a plurality of inlet manifolds and a plurality of outlet manifolds are disposed on a cooling surface of any one separator among the cooling surface of the cathode separator and the cooling surface of the anode separator. The plurality of first gaskets are configured to allow cooling air for cooling the cooling surface to flow between first gaskets adjacent to each other.

Abstract: Disclosed is a separator for a fuel cell. The separator includes a separator main body formed in a plate shape such that a first surface thereof forms a reaction surface and a second surface thereof forms a cooling surface, each of which has a reaction area at a center portion thereof and formed with multiple manifold areas through which multiple manifolds to which a reaction gas or a coolant is respectively introduced or discharged pass to opposite sides of the reaction area, and in which a pair of diffusion areas that diffuse the reaction gas or the coolant are formed between the reaction area and the pair of manifold areas, and includes multiple flow path guide gaskets formed on the pair of diffusion areas and configured such that multiple diffusion flow paths dispersed to the reaction area from at least a pair of the manifolds respectively formed on the pair of manifold areas are formed.
