Abstract:It is an efficient way to improve the properties of proton exchange
   membranes （PEMs） by the method of chemical cross-linking. The
   cross-linked PEMs have the advantages of low water uptake, low methanol
   crossover, high thermal and mechanical stability. There are three
   methods to perform cross-linking. These are sulfonation of a
   cross-linked polymer, cross- linking of a sulfonated polymer, and
   cross-linking of a polymer blending system. Different cross-
   linkingmethods lead to different cross-linking sites and consequently
   different properties of the PEMs. Cross-linking degree, ion exchange
   capacity or cross-linker species may have profound effects on
   microstructure and properties of the cross-linked membranes. They should
   be optimized in order to make the best of the properties of cross-linked
   PEMs.
