ELECTRODE CATALYST, MANUFACTURING METHOD THEREOF, FUEL ELECTRODE, AND FUEL CELL APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an electrode catalyst for a direct liquid fuel supply type fuel cell which can offer the fuel cell with high output and long lifetime by increasing the acid resistance of the electrode catalyst using a perovskite compound as a carrier.

SOLUTION: This methanol oxidation catalyst is an electrode catalyst for a direct liquid fuel supply fuel cell, including metallic particles having the liquid fuel oxidation catalyst capability and the oxygen deficient form perovskite oxide represented as ABO3-δ, where δ indicates deficient amount of oxygen in the range of 0.01≤δ≤1.0. Each of A and B site elements is at least one kind of element which is selected from the elements forming the acidic oxide or amphoteric oxide through bonding with oxygen.
