Separator for fast polymerelektrolytisk brenselbatteri
摘要
A separator for a solid polymer electrolyte type fuel cell wherein multipile single cells are laminated and made up of a solid polymer electrolyte layer and catalyst electrode layers, gas diffusion electrodes and separators disposed on either side of the solid polymer electrolyte layer, and a fuel cell using the separator. At least a part of the separator to make contact with a gas diffusion layer is coated with a coating layer including a conducting hard carbon film. As a result, the separator has superior corrosion resistance and the fuel cell has a minimal internal resistance. <IMAGE>
