| 主权项 | 1. A process for producing fuel cell catalysts, comprising a step (I) of heating a transition metal-carbonitride in an inert gas that has an oxygen concentration in the range of 0.1 to 10% by volume, and a step (II) of heating the product from the step (I) in an inert gas that has an oxygen concentration of not more than 10 ppm, wherein the heating temperature in the step (I) is in the range of 400 to 1200° C., and wherein the heating temperature in the step (II) is in the range of 800 to 1400° C. | ||
