ABSTRACT:
A method of manufacturing an anode for a fuel cell including: performing an acid treatment for a carbon-based compound; washing the resultant obtained from the acid treatment with water and then performing a freeze-drying (lyophilization) process; forming a microporous diffusion layer by dispersing the lyophilized resultant in a solvent, coating the dispersed resultant on a porous carbon support, and drying; and forming a catalyst layer on top of the microporous diffusion layer, an anode for a fuel cell obtained according to the method herein, and a fuel cell using the same. An anode having improved efficiency on liquid fuel diffusion can be obtained when using the fuel diffusion layer including the microporous diffusion layer formed of the carbon-based compounds obtained after an acid treatment and a freeze-drying process according to the present invention. A fuel cell having improved performance can be manufactured by using such an anode.
