Abstract:
A method of treating a carbon substrate, includes the successive steps of impregnating the carbon substrate with an aqueous solution containing an amorphous fluorinated copolymer of tetrafluoroethylene and of perfluoromethoxy dioxole, drying the carbon substrate at a pressure lower than the atmospheric pressure, and obtaining a carbon substrate impregnated with a fluorinated copolymer. Such a carbon substrate may be used as a gas diffusion layer in a fuel cell.
