A cell for a fuel cell, having an electric power generation region in which an assemblyand first and second gas diffusion layersare laminated to enable electric power generation, and a manifold region which is formed at the periphery of the electric power generation region and in which manifold openingsare formed to allow the passage of a gas or the like, wherein one of the first and second gas diffusion layersextends to the manifold region, and a peripheral edge portionis hermetically sealed by impregnation with a liquid resin that is used for forming a gasketaround the periphery of the manifold opening. The porosity of a boundary portionof the first and second gas diffusion layersis smaller than the porosity of the electric power generation regionand the peripheral edge portion
