英文摘要: In this paper, 1,2,4-triazolium methanesulfonate (C2H4N3+CH3SO3-, [Tri][MS]), an ionic conductor, was successfully synthesized. It exhibited high ionic conductivity of 18.60 mS.cm(-1) at 140 degrees C and reached up to 36.51 mS.cm(-1) at 190 degrees C. [Tri][MS] was first applied to modify Nafion membrane to fabricate [Tri][MS]/Nafion membrane by impregnation method at 150 degrees C. The prepared composite membrane showed high thermal stability with decomposed temperature above 200 degrees C in air atmosphere. In addition, the membrane indicated good ionic conductivity with 3.67 mS.cm(-1) at 140 degrees C and reached up to 13.23 mS.cm(-1) at 180 degrees C. The structure of the [Tri][MS] and the composite membrane were characterized by FTIR and the compatibility of [Tri] [MS] and Pt/C catalyst was studied by a cyclic voltammetry (CV) method. Besides, the [Tri][MS]/Nafion membrane (thickness of 65 mu m) was evaluated with single fuel cell at high temperature and without humidification. The highest power density of [Tri][MS]/Nafion membrane was 3.20 mW.cm(-2) at 140 degrees C and 4.90 mW.cm(-2) at 150 degrees C, which was much higher than that of Nafion membrane.
