| Abstract: | Active carbon supported Au-Pt catalyst(Au-Pt/C) with different Pt/Au atom ratios was prepared and the effect of Pt/Au atom ratio on the electrocatalytic performance of Au-Pt/C in direct formic acid fuel cell(DFAFC) like the oxygen reduction ability and tolerance to formic acid was investigated.Comparing with Au/C catalyst,the Au-Pt/C catalyst exhibits better electrocatalytic performance towards the reduction of oxygen.With the increase of Pt/Au atom ratio from 0/50 to 2/48,Au-Pt/C catalyst shows excellent e... |
