Abstract
A method of forming a catalyst material includes coating agglomerates of catalyst support particles with an ionomer material. After coating the agglomerates of catalyst support particles, a catalyst metal precursor is deposited by chemical infiltration onto peripheral surfaces of the agglomerates of catalyst support particles. The catalyst metal precursor is then chemically reduced to form catalyst metal on the peripheral surfaces of the agglomerates of catalyst support particles.
