英文摘要Fabrication of novel electrode materials with ordered proton-migration channels is an effective strategy to enhance the proton conductivity of the electrode for polymer electrolyte membrane fuel cells. Here we report the electrochemical fabrication of ordered Nafion (R) ionomers decorated polypyrrole nanowires to construct the ordered proton-migration channels. Based on the electrostatic interaction between Nafion (R) ionomers and the polymer intermediate, ordered Nafion (R) ionomers decorated polypyrrole nanowires could be fabricated via chronoamperometry with varying contents of Nafion (R) ionomers. The morphologies, charge-storage performances, electron conductivity and proton conductivity of the composites are investigated by scanning electron microscopy, cyclic-voltammetry, galvanostatic charge-discharge measurement and electrochemical impedance spectroscopy. With the modification effect of Nafion (R) ionomers on polypyrrole nanowires, the composite shows greater ordered structure relative to another without Nafion (R) ionomers and the electrochemical performances change with the content of Nafion (R) ionomers. The composite could achieve a high specific capacitance of 356 F/g at 1 A/g with a 0.62-fold enhancement compared to polypyrrole nanowires without Nafion (R) ionomers. It also displays a superior electrical conductivity of 49 S/cm and a quite high proton conductivity of 0.014 S/cm at working conditions of fuel cells, which are associated with the requirements of fuel cells and have the potential to be the electrode material for a large range of electrochemical energy conversion devices.
