abstract = "The cathode electrocatalyst layers were prepared by in situ growing Pt nanowires (Pt-NWs) in two kinds of matrixes with various Pt loadings for proton exchange membrane fuel cells (PEMFCs). Commercial carbon powder and 20 wt.% Pt/C electrocatalyst were used as the matrix material for the comparison. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), polarization curves tests, and electrochemical impedance spectroscopy (EIS) were carried out to examine the effects of the matrix materials on the Pt-NW growing and the electrode performance. The optimum Pt-NW loadings of 0.30 mg cm-2 in the carbon matrix (CM) and 0.20 mg cm-2 for the Pt/C matrix (PM) were obtained.
