Abstract:
A fuel cell includes a first electrically conductive plate and a first gas diffusion layer. The first gas diffusion layer is disposed over the first electrically conductive plate. Characteristically, the first gas diffusion layer comprises a first fibrous sheet having fibers coated with an electrically conductive layer. A first catalyst layer is disposed over the first gas diffusion layer and an ion conducting membrane is disposed over the first catalyst layer. The fuel cell also includes a second catalyst layer disposed over the ion conducting membrane with a second gas diffusion layer disposed over the second catalyst layer. A second electrically conductive plate is disposed over the second gas diffusion layer. Methods for forming the gas diffusion layers and the fuel cell are also provided.
