摘    要:研究一种新型免增湿无机-有机复合质子交换膜,这种复合质子交换膜中的无机物含量达60%以上,且其中部分无机颗粒交联成为无机大分子,具有良好的耐酸稳定性。化学结合水到120℃左右才分解,在80℃干燥30min后,在潮湿的空气中(RH90%)可自动吸湿恢复原重。在干燥空气(相对湿度<40%)中具有良好的导电能力,室温电导率达1.14×10-2S/cm,在60℃时达到2.81×10-2S/cm。

关 键 词:燃料电池  复合质子交换膜  增湿

Abstract:A new inorganic and organic composite membrane with above 60% inorganic materials was developed in this paper. The composite membrane possessed good sulfuric acid resistance because part of inorganic materials crosslinked in drying. After being dried at 80℃ for 30min, the membrane could restore its original weight in moisture air, and the chemically combined water in the membrane dissolved until to 120℃,therefore the membrane showed excellent proton conductivity even in dry air with relative humidity below 40%. The conductivity was 1.14×10-2 S/cm at room temperature and increased to 2.81×10-2S/cm at 60℃. Without any humidification, the power density of this composite membrane was twice that of Nafion117 at room temperature.
Keywords:fuel cell  composite proton exchange membrane  humidification
