CATALYST PARTICLES FOR FUEL CELLS AND METHOD FOR PRODUCING SAME

摘要

Catalyst particles (1) for fuel cells according to the present invention comprise: metal particles (2) which are formed of either a metal other than a noble metal or an alloy of a noble metal and a metal other than a noble metal; and noble metal layers (3) which are formed on the surfaces of the metal particles (2) and have a thickness of 1-3.2 nm. The catalyst particles for fuel cells are able to have improved catalytic activity, while reducing the amount of a noble metal by having the above-described configuration. The catalyst particles (1) for fuel cells according to the present invention are able to have improved catalytic activity, while reducing the amount of a noble metal.
