Manufacture New Catalyst PtCuCeO<sub>x</sub> for Fuel Cells by IBS and Modified by Post-Processing

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 PtCuCeO x 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 CeO x 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.
