摘要

A conductive catalyst particle manufacturing method in which a homogeneous catalyst material is adhered to all conductive particles by a physical vacuum evaporation, a gas−diffusing catalyst electrode manufacturing method, an apparatus used for a conductive catalyst particles, and a vibrator are disclosed. In the conductive catalyst particle manufacturing method, a catalyst material (18) such as Pt is adhered to conductive particles (1) such as carbon particles by a physical vacuum−evaporation such as sputtering while vibrating both the conductive particles (1) placed on a vibrating surface (20) and balls functioning as vibration amplifying means and also placed on the vibrating surface (20). The gas−diffusing catalyst electrode manufacturing method comprises a step of fabricating a gas−diffusing catalyst electrode containing the thus manufactured conductive catalyst particles. The conductive catalyst particle manufacturing apparatus comprises vibrating means for vibrating conductive particles (1), physical vacuum−evaporating method for adhering a catalyst material (18) to the surfaces of the conductive particles (1), and means for amplifying the vibration.
