摘要
针对磺化聚砜质子交换膜用于PEMFC ,研究了它的物理化学性能和电化学性能 ,实验结果表明 :与Nafion 膜相比 ,磺化聚砜 (EW =90 0 )作为质子交换膜材料 ,具有较好的热稳定性、水化性能和尺寸稳定性 ,溶液浇铸法制得的磺化聚砜膜在机械强度、气体渗透性能方面与Nafion 膜相近 ,用磺化聚砜膜组装的PEMFC的电池性能与Nafion 膜相比存在一定的差距 ,但从电池运行稳定性来看 ,还是有希望用于质子交换膜燃料电池的 .
In this work,the physico-chemical and electrochemical performance of sulfonated polysulfone were studied.Sulfonated polysulfone membranes swelled less than Nafion membranes did. The proton conductivities in sulfonated polysulfone membranes are lower than in Nafion membranes when the two membranes have same EW values.It appears that the sulfonated polysulfone membranes looks promising for proton exchange membrane fuel cell applications.
