METHOD FOR MANUFACTURING ELECTRODE CATALYST FOR FUEL CELL, ELECTRODE CATALYST FOR FUEL CELL, AND SOLID POLYMER ELECTROLYTE FUEL CELL COMPRISING THE SAME

摘要

A method for producing an electrode catalyst for a fuel cell, including: an immersion step (step A) for immersing one or more selected from a catalyst component, a carrier of conductive particles, and a polymer electrolyte in a solvent; a catalyst loading step (step B) for loading the catalyst component on the carrier; and a reaction site forming step (step C) for depositing the polymer electrolyte onto the catalyst-loaded carrier, characterized by irradiating ultrasonic waves in at least one of steps A, B, and C. In the present invention, by suppressing a catalyst from being loaded inside the pores of a carrier, a method for producing an electrode catalyst for a fuel cell which increases the utilization rate of a noble metal catalyst and which improves power generation performance, an electrode catalyst for a fuel cell, and a solid polymer fuel cell provided therewith which can obtain high cell output can be obtained.
