MANUFACTURING METHOD OF ELECTROCATALYSTS FOR FUEL CELL ENABLING MASS PRODUCTION

摘要

PURPOSE: A manufacturing method of electrode catalyst is provided to have excellent diffusion efficiency by applying the duster and ultrasonic device at the same time, and an excellent production efficiency by using the centrifuge step and washing process, thereby enabling the mass production. CONSTITUTION: A manufacturing method of electrode catalyst comprises the steps of: pre-processing a mixture of ethylene glycol and a support element(S101), injecting platinum precursor to the pre-processed mixture and performing mixing(S103), putting acid solution into the mixture for stabilization(S105), centrifugally separating the stabilized mixture to extract electrode catalyst(S107), washing the electrode catalyst(S109), and heating the washed electrode catalyst(S111).
