  • Abstract This study prepared and charactered of Pt/CNT as cathodic catalyst layer in a PEM fuel cell. The experiment focused on the cathodic catalyst layer, were investigated three parameters of the vector species, Platinum loading and nafion solution content. The polarization curves, electrochemical impedance spectroscopy, cyclic voltammetry, thermal gravimetric analysis and X-ray diffractometer analysis were measured by fuel cell testing machine. The results show that acidification carbon nanotubes as a carrier has the best performance, and reducing the Platinum loading causes the fuel cell performance degradation. Platinum loading and Nafion solution content are related to each other. When reducing the platinum load and increasing the content of Nafion solution, the fuel cell performance can be improved and achieve the goal of reducing the use of Platinum. The research results can help catalyst layer technology improvement and enhance the PEM fuel cell performance.
