Recently, polymer electrolyte membrane fuel cell (PEMFC) has received a huge amount of attention as one of alternative energy sources where Pt is most widely used as electrochemical catalyst However, Pt is so expensive that it contributes more than 50 % of total cost for PEMFC. This is one of main reason preventing it from the commercialization. In order to resolve this problem, Pt –transition metal (Pt-M, M = Pd, Fe and Ni) alloy catalysts are synthesized and deposited on nitrogen doped carbon black (NCB). Electrochemical and physical properties of Pt-M alloys/nitrogen-doped carbon black (Pt-M/NCB), especially the oxygen reduction reaction (ORR) are investigated by various instruments. Finally, a single cell test is conducted for Pt-M/NCB as the cathode catalyst. |
