英文摘要：

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.
