Abstract：

To improve the comprehensive performance of anion exchange membranes (AEMs) for fuel cells, a seires of AEMs with different functional groups was designed and prepared. Poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) was used as backbone, and 1,6-bis-(dimethylamino)-hexane (TMHDA) was used as crosslinker. Then structures and electrochemical performance of prepared AEMs were investigated. The results show that all AEMs have good hydroxide conductivity, satisfactory dimensional stability and high chemical stability. Among them, the c-PPO-DIEA membrane has the highest ionic conductivity (72.3 mS/cm, 80 °C). Moreover, ionic conductivity of this kind of AEM can still remain 80.2% after immersing in alkaline solution for 20 days, showing alkaline resistance. In conclusion, the c-PPO-DIEA AEM shows a great potential for application in fuel cells.
