Claims24
A process for producing conductive catalyst particles, the process comprising causing a catalytic substance to adhere to a surface of a conductive powder by physical vapor deposition while vibrating the conductive powder, wherein the conductive powder undergoes vibration together with vibration amplifying means arranged on a vibrating plane.
The process for producing conductive catalyst particles as defined in claim 8, wherein the conductive powder includes an electric resistance lower than about 10−3 Ω·m.
A process for producing a catalyst electrode capable of gas diffusion, the process comprising the steps of:
- causing a catalytic substance to adhere to a surface of a conductive powder by physical vapor deposition while vibrating the conductive powder together with vibration amplifying means on a vibrating plane, thereby producing one or more conductive catalyst particles and preparing the catalyst electrode with the conductive catalyst particles.
