摘要

用高磺化度的磺化杂萘联苯聚醚酮（SPPEK）制备DMFC质子交换膜时，膜的机械强度会因过度溶胀而下降。通过在SPPEK（DS=61%）中掺杂1

4-三羧基丁烷-2-膦酸锆(Zr(PBTC))，我们制备出 Zr(PBTC)/SPPEK复合质子交换膜。实验表明

Zr(PBTC)的掺杂能有效降低膜的吸水量（溶胀），并能减小膜的甲醇透过系数。80℃时，30wt.%Zr(PBTC) /SPPEK复合膜的吸水量与SPPEK膜比降低了30％。室温下复合膜的甲醇透过系数在10－7 cm2.s-1数量级上，比Nafion 115膜低一个数量级以上。液体甲醇溶液进料的DMFC单电池测试表明，30wt.%Zr(PBTC) /SPPEK复合膜的电池性能优于SPPEK的电池性能。

Abstract

In order to improve the property of sulfonated poly（pathalazinone ether ketone）(SPPEK)membrane of high sulfonation degree，proton conductor zirconium tricarboxybutylphosphonate［Zr（PBTC）］was used and incorporated into SPPEK to prepare Zr（PBTC）/SPPEK composite membranes for direct methanol fuel cell(DMFC).The results showed that the additive could reduce the water swelling and methanol permeability of membranes efficiently without sacrificing its conductivity.DMFC single cell performance demonstrated that the 30%(mass)Zr（PBTC/SPPEK composite membrane was better than the pristine SPPEK membrane for its reduced swelling and consequently improved dimensional stability.
