Platinum (Pt)-based electrodes are the most widely used oxygen reduction reaction (ORR) electrocatalysts in proton exchange electrolyte fuel cell (PEMFC). Although fuel cell using platinum as cathode catalyst has the outstanding performance for ORR, it has plenty of drawbacks, such as CO poisoning effects, high cost of Pt catalyst for commercialization, and unfavorable stability. In this regard, the carbon based electrodes, such as graphene, carbon nanotubes, and carbon black, have been widely investigated in order to overcome the drawbacks of platinum catalysts. In this study, the electrochemical properties and the stability of the advanced Pt-N doped carbon based electrode were reported compared with conventional Pt-based electrodes. As a result, this advanced Pt-N doped carbon based catalyst showed the significantly high stability and electrical performance, 1.7W mg-1pt , compared with commercial Pt-based catalyst (Pt/C) , 1.4W mg-1pt at 70oC. |
