摘　　要：测试分析了 3种不同离子交换膜材料的水存留量、溶涨率和离子导电率 ,结果表明水存留量高的膜材料溶涨率和离子导电率也相应较大。对不同离子交换膜材料的耐热和耐压稳定性测试结果发现 3种离子交换膜在2 0 0℃以下范围内都没有发生相变或其它结构性变化 ,失重率都低于 5 % ,因此 3种膜材料在 2 0 0℃以下温度范围内使用是安全可靠的。不同膜材料的耐压机械强度均随着热压处理温度升高而逐渐下降。在相同热压温度条件下的耐压强度为 :SH117B膜大于或等于Nafion117膜 ;Nafion117膜大于或等于SH117A膜。离子交换膜也是影响燃料电池放电性能的一个重要因素。Nafion117膜组装的燃料电池最大放电功率密度分别是SH117A膜和SH117B膜组装的燃料电池最大放电功率密度的 1 2 8倍和 2 4倍。The water holding content,swelled after absorbing water and ion conductivity were tested for the three different ion exchange membranes,the results indicated that the one which has higher water holding content would have higher swell after absorbing water and ion conductivity.The heat resistance and compression resistance of the ion exchange membrane were also tested,it was found that below 200℃,the three different ion exchange membranes do not have any change of configuration,and their weightlessness is under 5%.The compression resistance intensity of all three ion exchange membranes declines with temperature increasing.Under the same temperature condition, the order of the compression resistance intensity of three ion exchange membranes is SH117B larger than or equal to Nafion117;and Nafion117 is larger than or equal to SH117A .The ion exchange membrane is also an important affecting factor.
