  • Abstract In the study, we have considered the effect of dual-layer structured cathode catalyst layer with electrospun Pt nanowires and Pt/C ,determined the optimal dual-layer structured catalyst layer design parameters including Pt nanowires and Pt/C loading, Nafion content by measuring the variations of cell performance. The experiments have been used polarization curve, electrochemical impedance spectroscopy, cyclic voltammetry, exchange current density .
    The experiment results indicated the dual-layer structured cathode catalyst layer structure can effectively improve the fuel cell performance . The dual-layer structured with inner layer of Pt/C (Near the proton exchange membrane side)and outer layer of Pt nanowires (Near the gas diffusion layer side)could enhance the performance effectively, and the parameters discussed in when loading ration of 0.4 mg cm-2 Pt/C and 0.1 mg cm-2 Pt nanowires that the performance is fine. The cell have the best performance with inner layer is 30% and outer layer is 20%.
