摘　　要：Nafion膜是目前最常用的燃料电池用质子交换膜,具有良好的热稳定性和高质子传导率。然而其高昂的成本、低湿度和高温下较差的质子传导率,在一定程度上影响了质子交换膜燃料电池(PEMFC)的大规模应用。磺化聚醚醚酮(SPEEK)表现出与Nafion相当的质子传导性能,且在热化学性能、燃料渗透、低成本方面具有一定的优势,有望替代商用Nafion膜。本文介绍了SPEEK制备的两种方法,分析影响SPEEK性能的主要因素,并阐述目前SPEEK复合膜制备及其性能的研究进展,最后对SPEEK未来的研究方向进行了展望。The Nafion membrane widely used in proton exchange membrane fuel cell(PEMFC)possesses good thermal stability and high proton conductivity.However,its high cost,poor proton conductivity at low humidity and high temperature have affected large-scale application of PEMFC.Sulfonated poly(ether-ehter-ketone)(SPEEK)is expected to replace commercial Nafion membranes owing to its high proton condeuctivity,excellent thermochemical properties and low cost.In this paper,the preparation methods of SPEEK are introduced,the factors affecting the performance of SPEEK are analyzed,and the current research progress on the preparation and performance of SPEEK composite membranes is described.Finally,the main challenges and future direction are concluded.
