Fuel cells can directly convert chemical energy into electric energy with both high conversion efficiency and power density. Among many factors affecting the chemical−electrical energy conversion, oxygen reduction reaction (ORR) on the cathode is the pivot in fuel cell. This reaction is a kinetically slow process in comparison with the hydrogen oxidation taking place in the anode, So, almost the totality of the current research and development focuses on improving the cathode catalysts and electrodes]1-3[. Up to now, Pt and Pt-based alloys are found to have high activity for ORR and considered to be the most efficient Catalysts. However, the high cost, poor durability and CO deacti-vation of Pt-based alloys in FCs are the major drawbacks hindering their widespread commercial applications. Hence, searching novel and high performance catalysts, such as low cost, high energy conversion efficiency, high durability, etc.
