英文摘要	a new anion exchange membrane was synthesized by a green and facile route-chemically grafting polybenzimidazole (pbi) membrane with brch(2)ch(3). the obtained membrane was characterized by means of ex-situ and in-situ tests (edx, ftir, ac impedance, single cell test and so on). the results suggested that the group of -ch(2)ch(3) was successfully grafted onto n atom within pbi backbone, while with br(-) as counter ion. the corresponding ionic conductivity and ethanol permeability were about 0.022 scm(-1) and 5.24 x 10(-8) cm(2)s(-1) respectively. finally, single cell test suggested that air-breathing alkaline direct ethanol fuel cell with quaternized pbi membrane can deliver a peak power density of about 11 mwcm(-2) even at ambient temperature of 13 degrees c, which was better than those of air-breathing alkaline direct methanol fuel cell in literatures. in addition, a possible reaction mechanism was also proposed and discussed. copyright (c) 2011, hydrogen energy publications, llc. published by elsevier ltd. all rights reserved.
