【摘要】 本文制备了直接甲醇燃料电池用的两种离子液体（[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。更多还原

【Abstract】 Two kinds of ionic liquid（[α-MPyH][Tfa]and[EMIm][BF₄]） based composite membranes for DMFC were prepared in this paper.Their morphology and their electrochemical properties were characterized,as well. Impedance spectroscopy test shows 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.更多还原
