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.
