Proton Exchange Membrane Fuel Cells (PEMFCs) are highly efficient and non-polluting electrical power generators based on two electrochemical reactions. Therefore, PEMFCs are considered to be alternative electricity sources for electric vehicles, portable applications and stationary power systems due to their high power density and eco friendly environment. However, PEMFCs are associated with many problems for their commercialization. The both electrode catalysts with platinum is one of the more serious problems since platinum is the noble metal. On the other hand, the slow rate of the Oxygen Reduction Reaction (ORR) leads to a higher over potential at the cathode. In this study, PtFe/C cathode catalysts were prepared using the chemical reaction method to develop cathode catalyst with higher catalytic activity for the ORR. The catalytic activity for the ORR of PtFe/C catalysts was evaluated using electrochemical measurement.
