METHOD FOR PREPARING ELECTRODE FOR FUEL CELL, ELECTRODE AND FUEL CELL PREPARED USING THE SAME

摘要

PURPOSE: A manufacturing method of an electrode for a fuel cell is provided to improve the efficiency of the fuel cell and the activity of the electrode by improving the dispersibility of a catalyst and a binder inside catalyst slurry. CONSTITUTION: A manufacturing method of an electrode for a fuel cell comprises the following steps: producing catalyst slurry by mixing catalyst powder, a binder and a mixed solvent; coating the catalyst slurry on a material using a coater; and forming a catalyst layer by drying the coated catalyst slurry. The mixed solvent contains 19~66wt% of propanol, 30~66wt% of water, 2~8wt% of ethanol, and 0.1~9wt% of ethylene glycol. The catalyst slurry contains 3~40 parts of binder by weight, and 20~500 parts of mixed solvent by weight for 100 parts of catalyst powder by weight.
