| 英文摘要 | the alkaline stability of 1,2-dimethylimidazolium with various n3-substituents (including butyl, benzyl and vinylbenzyl) and corresponding quaternary ammonium small molecular compounds, and the 1,2-dimethylimidazolium- and quaternary ammonium-based membranes are systemically studied in the same condition. the spectroscopy (such as nmr, ft-ir, xps and mass spectrum) results of the two kinds of small molecular compounds indicate that the quaternary ammonium cations are more stable than 1,2-dimethylimidazolium cations in 3 m koh at elevated temperature, especially at 80 degrees c. moreover, the alkaline stability of the 1,2-dimethylimidazolium cations would be influenced by the n3-substitutions of the imidazolium, and n3-butyl substituted cation shows a better alkaline stability. the quaternary ammonium-based membrane are also more stable than the 1,2-dimethylimidazolium-based membrane in 1 m koh at 60 degrees c. in addition, the performance of the alkaline direct methanol fuel cell using quaternary ammonium-based membrane (22 mw cm(-2)) is much better than that of the fuel cell using 1,2-dimethylimidazolium-based membrane (0.04 mw cm(-2)).
