英文摘要: Four kinds of composite membranes were prepared by the solution-cast method with Nafion resin, poly(tetrafluoroethylene), and different types of SiO(2). They are SiO(2) sulfonated by 1,3-propane sultone (denoted as SiO(2)-1,3PS), SiO(2) sulfonated by H(2)SO(4) (denoted as SiO(2)-SO(3)H), and pure SiO(2). The SiO(2) content was controlled at 5% in the composite membranes. Combined with the results of the electrochemical impedance spectroscopy, water uptake, and fuel cell performance of different membranes, it suggested the organically modified SiO(2) has a weak water uptake ability due to the organic molecule chain.
