Abstract
A gas diffusion layer that is usable with a fuel cell includes a material that is adapted to permit a reactant of the fuel cell to diffuse through the material. The material includes flow channels for communicating the reactant so that at least a portion of the reactant diffuses through the material to a membrane of a fuel cell. The gas diffusion layer may be received by a recessed portion of a plate.
