Abstract:
A fuel cell stack is provided to improve the flow of cooling water and reactant gas. The fuel cell stack includes a cooling water diffusion portion provided on each of the anode separator and the cathode separator. A first cooling water flow path area is provided between a land formed on the cooling water diffusion portion of the anode separator and a channel formed on the cooling water diffusion portion of the cathode separator. A second cooling water flow path area is provided between a channel formed on the cooling water diffusion portion of the anode separator and a land formed on the cooling water diffusion portion of the cathode separator. In addition, the first cooling water flow path area and the second cooling water flow path area are parallel with each other within at least a part of the cooling water diffusion portions.
