Abstract: A separator assembly for a fuel cell and a fuel cell stack including the same, is uniformly capable of forming a surface pressure of a region where a reaction gas flows when a stack is stacked by adjusting a height and shape of a gasket line for each region in which the reaction gas flows.

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.

Abstract: A separator assembly for a fuel cell able to prevent deformation of a separator due to a flow pressure of a reaction gas at a first reaction gas inlet, and a fuel cell stack including the same includes: a first separator on one face of which is formed with a first reactive surface over which first reaction gas flows to allow for first reaction gas and second reaction gas to react and on the other face of which is formed with a first cooling surface where cooling occurs; a second separator on one face of which is formed a second reactive surface positioned to face the first reactive surface of the first separator, over which second reaction gas flows to allow for first reaction gas and second reaction gas to react, and on the other face of which is formed a second cooling surface where cooling occurs;, and a reinforcing plate which is positioned in a region of the first separator where first reaction gas enters, preventing deformation of the first separator.
