Novel Gas Diffusion Electrodes (GDEs) for Polymer Electrolyte Membrane Fuel Cells (PEMFCs) were prepared by in situ growing Pt-Pd nanowires on carbon paper using a facile deposition method at room temperature. Pt-Pd nanowires, wit a diameter of 26.87-37.23 nm and length of 717.1-926.9 nm, were regularly coated on the carbon fiber surfaces in carbon paper. This method was much simpler than the traditional method for preparing GDEs because there were no processes needed to make the ink the catalysis layer or vacuum for sputter the catalysts. The impedance spectroscopy and cyclic voltammetry measurement showed that the as-prepared GDE possessed a lower charge transfer resistance and a higher EAS than did the conventional one with Pt/C nanoparticles. The excellent performance obtained and the simple steps made the process a promising technique for preparing GDEs in PEMFCs for commercial applications.
