PROCESS FOR PRODUCING FUEL CELL CATALYSTS, AND FUEL CELL CATALYST

摘要

The invention provides processes for producing fuel cell catalysts that are not corroded in acidic electrolytes or at high potential and have excellent durability and high oxygen reducing ability. The process for producing fuel cell catalysts includes a step (I) of heating a carbonitride of a transition metal in an inert gas containing oxygen, and a step (II) of heating the product from the step (I) in an inert gas that does not substantially contain oxygen.
