Abstract
A fuel cell including a power generating body including an electrolyte layer and electrode layers, diffusion layers disposed on opposite major surfaces of the power generating body, separators disposed on major surfaces of the diffusion layers opposite to those facing the power generating body, a first seal formed around the periphery of the power generating body and including an effective seal portion that suppresses leakage of the gas to the outside of the fuel cell between the separators, and a second seal formed integrally with at least one of the diffusion layers to extend along an end face of the diffusion layer. The second seal is in intimate contact with a surface of the power generating body on which the diffusion layer is laminated and a surface of a corresponding one of the separators that is laminated on the diffusion layer.
