Abstract
A method for producing the same and terrorism anode material to the conductive carbon nano that was supported oxide no problem, such as terms of price and [challenge] CO oxidation activity. As Abstract anode material, a CeO2 powder not doped 1 × 10m2 / g or 1 × 102m2 / g or less and a specific surface area of the specific surface area, and not a solid solution and conductive carbon, the component of the rare earth elements and SnO2 powder of 1 × 10m2 / g or more 1 × 102m2 / g or less, an average secondary particle diameter to use a mixture of Pt of 30 nanometers or less.
