ELECTRODE CATALYST FOR FUEL CELL CATHODE EXCELLENT IN CARBON CORROSION RESISTANCE, AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a novel powdery electrode catalyst for PEFC cathode excellent in carbon corrosion resistance more than a conventional one and provide a practical method of manufacturing the same.SOLUTION: In the method of manufacturing the electrode catalyst for a fuel cell cathode, after gold-core platinum-shell nano particles, which are prepared by using a protective agent in a liquid phase reduction method, are carried on a carbon particle carrier and are calcined in an oxygen-containing atmosphere, the protective agent is removed.
