    • A gas diffusion layer for a fuel cell includes a gas diffusion layer substrate and a microporous layer formed on the surface of the gas diffusion layer substrate. The microporous layer is formed into a sheet-like shape including a binder and a carbon material containing at least scale-like graphite, and the sheet-like microporous layer is attached to the gas diffusion layer substrate. The gas diffusion layer for a fuel cell having such a configuration, prevents the components included in the microporous layer from entering the gas diffusion layer substrate, so as to ensure gas permeability. In addition, the scale-like graphite contained in the microporous layer as an electrically conductive material improves electrical conductivity and gas permeability. Accordingly, the gas diffusion layer contributes to an improvement in performance of a polymer electrolyte fuel cell.
    • 燃料电池用气体扩散层包括形成在气体扩散层基板的表面上的气体扩散层基板和微孔层。 微孔层形成包括粘合剂和至少含有鳞状石墨的碳材料的片状,并且片状微孔层附着在气体扩散层基板上。 具有这种结构的燃料电池用气体扩散层能够防止微孔层中所含的成分进入气体扩散层基板,以确保透气性。 此外,作为导电性材料的微孔层中所含的鳞状石墨,提高了导电性和透气性。 因此,气体扩散层有助于提高聚合物电解质燃料电池的性能。
