英文摘要	imidazolium-functionalized anion exchange membranes (aems) for anion exchange membrane fuel cells (aemfcs) were synthesized by functionalization of chloromethylated poly (ether sulfone) (pes) with 1-alkylimidazole. the properties of aems can be controlled by the degree of chloromethylation of pes. moreover, with the increment of the alkyl line length on the imidazolium group, the water uptake, swelling ratio and solubility of aems increased, whereas the hydroxide conductivity declined. by dissolving aems in the mixture of ethanol and water, im-based anion exchange ionomers (aeis) can be obtained. electrochemical studies revealed that the catalytic activities of pt/c towards oxygen reduction and hydrogen oxidation in the presence of imidazolium-functionalized aeis were almost the same with that of commercial quaternary ammonium-based ionomers. the fabricated aem and aei were utilized to assemble h-2/o-2 aemfc, yielding a peak power density of similar to 30 mw cm(-2) with open circuit potential larger than 1.0 v. the results obtained indicate that imidazolium-functionalized aems and aeis may be candidates which are worth further investigation for the application in the aemfcs. copyright (c) 2013, hydrogen energy publications, llc. published by elsevier ltd. all rights reserved.
