英文摘要：

In recent years, many studies show that double noble metal catalysts have good prospects in the improvement of efficiency and reduction of cost for low temperature fuel cell. This article reviews the research status of Pt-Ru, Pt-Au, Pt-Pd and Pd-Au alloy or core-shell catalysts, and makes brief comments on the research priorities and development foreground of double noble metal catalysts for researchers＂ referenee.
