摘　　要：制备了直接甲醇燃料电池用的2种离子液体([α-MPyH][Tfa]和[EMIm][BF4])复合膜,并对二者的微观形貌以及电化学特征予以表征.阻抗测试结果表明,[EMIm][BF4]复合膜的电导率高于[α-MPyH][Tfa]复合膜,计时电流法对二者阻醇性能研究结果表明,[EMIm][BF4]复合膜的阻醇性能也好于[α-MPyH][Tfa]复合膜.Two kinds of ionic liquid （[α-MPyH][Tfa] and [EMIm][BF4]） based composite membranes for DMFC were prepared.Their morphology and their electrochemical properties were characterized.Impedance spectroscopy test shows the conductivity of [EMIm][BF4] based composite membrane is higher than that of the [α-MPyH][Tfa] based composite membrane.Similarly,the methanol-resistance of the [EMIm][BF4] based composite membrane is better than that of the [α-MPyH][Tfa] based composite membrane.
