| description | The embodiment of the invention provides carbon felt, carbon paper, a preparation method of the carbon felt and the carbon paper and a fuel cell membrane electrode, and belongs to the technical field of fuel cells. The carbon felt obtained by the preparation method of the carbon felt has the carbon fiber layer, the reinforced fiber layer and the carbon fiber layer, and the carbon paper prepared by using the carbon felt subsequently has a main body structure of the carbon fiber resin carbon layer, the resin carbon layer and the carbon fiber resin carbon layer, so that the pore degree of the carbon paper can be improved, and a Venturi tube effect can be generated on a diffusion channel; a pressure gradient is formed, the conveying efficiency of gas and liquid is improved, and the mass transfer and heat transfer efficiency of the fuel cell are effectively improved; the strength and the bending resistance of the carbon paper can also be effectively improved.
