| Abstract: | The methanol and ethanol electrochemic characteristic behaviors on the two kinds of commercial catalyst Pt/C and PtRu/C in acid solution were compared by carrying out Cyclic voltammograms. The experimental results showed that the PtRu/C has a higher electrocatalytic activity for the two fuels in low temperature fuel cell than Pt/C. and even the PtRu/C can availably avoid CO-poisoning. |
