Abstract

See full text

A gas diffusion layer for proton exchange membrane fuel cell and preparation method thereof are provided. The preparation method is to papermake and dry carbon fiber suspension mainly composed of a fibrous binder, water, a dispersant and carbon fibers with different aspect ratios to obtain a carbon fiber base paper, and then carbonize and graphitize under the protection of nitrogen or inert gas to obtain a gas diffusion layer for proton exchange membrane fuel cell; where the fibrous binder is a composite fiber or a blend fiber composed of a phenolic resin and other resin; where the prepared gas diffusion layer for proton exchange membrane fuel cell has a pore gradient, and the layer with the smallest pore size is an intrinsic microporous layer.
