摘要：
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.
摘要（中）：
一种制造燃料电池用阳极的方法，包括：对碳系化合物进行酸处理; 用水洗涤从酸处理得到的结果，然后进行冷冻干燥（冷冻干燥）处理; 通过将冻干的产物分散在溶剂中形成微孔扩散层，将分散的产物涂布在多孔碳载体上并干燥; 以及在微多孔扩散层的顶部形成催化剂层，根据本文方法得到的燃料电池用阳极和使用该催化剂的燃料电池。 当使用包括由根据本发明的酸处理和冷冻干燥处理之后获得的碳基化合物形成的微孔扩散层的燃料扩散层时，可以获得提高液体燃料扩散效率的阳极。 可以通过使用这种阳极来制造具有改进性能的燃料电池。
