Seeking for reducing the cost of hydrogen energy fuel cells, one of the key points is reduce Pt loading in Pt/C catalytic electrode. Meanwhile, there is no negative impact about efficiency of electrode reactions. We manufactured PtCuCeOx catalyst for fuel cell by Ion Beam Sputtering (IBS). In this paper, the electrodes were processed by different annealing temperature and acid treatment temperature for post-processing. An appropriate amount of Cu dopant can reduce the Pt loading, and the catalytic performance won't reduce. Doping CeOx refined PtCu alloy crystal particle, active surface area of the electrode was improved. It had shown that Pt atoms accounted for 72%, Pt load 0.0618mg/cm2 by SEM + EDS and ICP-AES data. Performance of electrochemistry was increased by 40.5%. It showed the characteristics had low Pt loading with high performance of hydrogen evolution. |
