ELECTRODE CATALYST MATERIAL AND METHOD OF MANUFACTURING THE SAME |
摘要 |
The invention provides an electrode catalyst material in which a resistance loss is reduced by enhancing an electric conductivity as a whole of an electrode catalyst as well as suppressing a corrosion and a disappearance by a catalyst metal in a conductive catalyst support so as to prevent a dropout and an aggregation of a catalyst metal particle, and a method of manufacturing the same. The electrode catalyst material in accordance with the present invention is an electrode catalyst material for a fuel cell having a catalyst metal particle and a carbon support supporting the catalyst metal particle, in which a carbon support protection layer including a metal element is formed in a coating manner on a surface of the carbon support, a silicone is included at 20 atomic % or more in the metal element contained in the carbon support protection layer, and the silicone exists in a state of an oxide and a carbide.
