磺化聚醚醚酮质子交换膜的共混改性及在直接甲醇燃料电池的应用研究
发布时间：2021-11-11 13:40
随着化石能源的逐渐枯竭和环境污染的日趋严峻,开发新能源和新能量转换装置成为目前新能源领域的研究热点。直接甲醇燃料电池（Direct methanol fuel cell,DMFC）是一种将化学能直接转化成电能的装置,具有燃料来源广泛、比能量和比功率高、系统简单和环境友好等优点。质子交换膜（Proton exchange membrane,PEM）是直接甲醇燃料电池的核心部件,起到隔绝甲醇燃料渗透和提供质子传递通道的作用,PEM的性能优劣直接影响燃料电池的性能和使用寿命。目前,最常用的PEM为Dupont公司的Nafion系列膜,Nafion膜具有优良的质子导电性、高机械强度和化学稳定性,但Nafion的全氟骨架制备过程复杂,成本高,并会对环境造成污染,并且Nafion膜存在燃料渗透严重和高温低湿下质子导电性衰减等缺点,严重降低了直接甲醇燃料电池的能量密度和能量输出,所以开发高阻醇性能的新型聚合物质子交换膜替代Nafion是当前的研究热点。磺化聚醚醚酮（Sulfonated poly（ether ether ketone）,SPEEK）是工程塑料聚醚醚酮的磺化产物,具有甲醇渗透率低、机械...
