Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a method of manufacturing a gas diffusion layer for an electrochemical cell. SOLUTION: The method includes the steps of: (a) combining carbon particles and one or more surfactants in a typically aqueous vehicle to manufacture a preliminary composition, typically by high shear mixing; (b) adding one or more highly fluorinated polymers to the preliminary composition by low shear mixing to manufacture a coating composition; and (c) applying the coating composition to an electrically conductive porous substrate, typically by a low shear coating method.
