Patent ID: 7988834

Claim:
A process for producing conductive catalytic particles, the process comprising: vibrating a conductive powder; coating the conductive powder with an ionic conductor; and adhering a noble metal and an additive component at the same time to a surface of the ionic conductor coated on the conductive powder by physical vapor deposition in an amount ranging from 10 weight % to 1000 weight % of the conductive powder, wherein the noble metal is selected from the group consisting of Pt, Ir, and Rh, wherein the additive component is selected from the group consisting of boron, silicon oxide, vanadium oxide, tungsten oxide, gallium oxide, and mixtures thereof, wherein the noble metal and the additive component do not form a solid solution thereby forming the catalytic particles free of sintering, and wherein the conductive powder is selected from the group consisting of carbon having a specific surface area greater than or equal to about 300 m 2 /g, ITO and SnO 2 .
