<P>PROBLEM TO BE SOLVED: To provide an electrode catalyst for an electric double layer capacitor, a fuel cell or the like that has an excellent electrochemical initial characteristic, and excels in long-term stability of characteristics. <P>SOLUTION: Activated carbon is previously surface-oxidized by ozone, hydrogen peroxide and an oxygen-containing gas, and thereafter processed at a temperature of 200-1,300°C in the presence of ammonia, urea or its derivative. A nitrogen compound is produced on the surface of the activated carbon, this large amount of surface nitride exhibits a basic property, is chemically stable, and catalytically accelerates various chemical reactions. <P>COPYRIGHT: (C)2009,JPO&INPIT |
