Abstract: A fuel cell stack includes a first separator and a second separator that are adhered to face each other between adjacent membrane electrode assemblies (MEAs) and each have a plurality of manifolds, a reacting region, and a guide region disposed between the plurality of manifolds and the reacting region. In the fuel cell stack, a first cooling medium guide channel guiding flow of a cooling medium between the plurality of manifolds and the reacting region is formed in the guide region of the first separator; a second cooling medium guide channel guiding flow of the cooling medium between the plurality of manifolds and the reacting region is formed in the guide region of the second separator; and at least portions of the first cooling medium guide channel and the second cooling medium guide channel overlap to communicate with each other.

Abstract: A porous separator for a fuel cell is provided and features the shape of a passage aperture formed in a flow field plate. The modified shape of the passage aperture minimizes destruction of a gas diffusion layer or a membrane electrode assembly attributable to stress concentration. The porous separator has a flow field plate that includes a first contact portion that is in contact with a gas diffusion layer or a membrane electrode assembly; a second contact portion that is in contact with a coolant channel; and a connection portion that is connected between the first contact portion and the second contact portion. Additionally, a passage aperture is formed in the connection portion, wherein a portion of an inside surface of the passage aperture protrudes toward a center of the passage aperture.

Abstract: A fuel cell stack is provided that includes unit cells that include a manifold, an open end plate that is disposed at one side of the unit cells and that has a reaction gas inlet and outlet that are connected to the manifold, and a closed end plate that is disposed at the other side of the unit cells and that closes the manifold, In particular, the open end plate includes a first slanted surface that adjusts a flow of a reaction gas at a reaction gas inlet and a manifold interface. A first alignment protrusion forms the first slanted surface and that aligns the unit cells, and the closed end plate includes a second slanted surface that adjusts flow of a reaction gas at the manifold interface. Additionally, a second alignment protrusion forms the second slanted surface and aligns the unit cells accordingly.
