  • Method for producing electrode material for fuel cell, electrode material for fuel cell, and fuel cell using the electrode material for fuel cell
    Patent number: 8398884
    Abstract: Disclosed is a method for producing an electrode material for fuel cells, which electrode material has excellent electrochemical catalytic activity and uses a non-carbon conductive oxide carrier having high durability. Specifically disclosed is a method for producing an electrode material for fuel cells, which comprises the following steps. (1) A step wherein carriers mainly composed of tin oxide are dispersed in a solution containing a noble metal colloid, and the noble metal colloid is reduced so that the carriers are loaded with noble metal particles (2) A step wherein the carriers loaded with the noble metal particles are separated from the liquid and dried (3) A step wherein the dried carriers loaded with the noble metal particles are subjected to a heat treatment at a temperature of not less than 80° C. but not more than 250° C. in the presence of a reducing gas.
