    摘要: A method for accurately evaluating the performance of fuel-cell electrode catalysts, a method of search for fuel-cell electrode catalysts having excellent performance, and fuel-cell electrode catalysts having new and excellent catalytic activity searched for by the above method. In a method for evaluating the performance of fuel-cell electrode catalysts composed of conductive carriers on which catalytic metal is supported, the oxygen atom adsorption energy on the catalytic metal surface obtained through a molecular simulation analysis is used as an indicator of the performance evaluation. Suitable catalysts consist of Pt—Au or Pt—Au—B, wherein B is one or more metal chosen from the group of chrome (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), rhodium (Rh) and palladium (Pd) and wherein the content of Au is 6 atom % or less.
