摘要/Abstract

摘要： 综述了固体核磁共振(NMR)技术的特点及其在燃料电池用膦酸基质子交换膜分析研究中的应用,重点介绍了运用¹H、³¹P、²⁹Si固体NMR以及¹H、³¹P变温固体NMR技术表征膦酸基质子交换膜的化学结构、氢键网络和质子传导机理等方面的研究进展。该综述表明固体NMR技术是一种研究膦酸基质子交换膜中氢键网络以及局部质子移动性的有效手段,并能进一步探索其质子传导的机理,为固体NMR技术在其他类型质子交换膜研究中的应用给予借鉴,为质子交换膜结构的表征提供一种新的方法。

Abstract: In this paper,the characteristics of solid state NMR and its application in the analysis of phosphonic acid proton exchange membranes (PEM) are described briefly. The research progress of ¹H、³¹P、²⁹Si solid state NMR and ¹H、³¹P variable temperature solid state NMR in terms of the characterization of chemical structure,hydrogen bonding network and proton conduction mechanism of phosphonic acid PEM are introduced. All these applications indicate that solid state NMR is an effective technique for the study of hydrogen bonding network and the local proton mobility of PEM,thereby it can be used to explore the mechanism of proton conduction. Also,it can give reference to the research of other kinds of proton exchange membranes by providing a new method for characterization.

Key words: solid state NMR, fuel cells, phosphonic acid proton exchange membranes, hydrogen bond network, proton conduction
