摘要：

We report the use of all-hydrocarbon anion exchange membranes capable of achieving high current densities through the optimization of MEA fabrication and operating conditions. The electrochemical behaviour of commercially-available Aemion (TM) anion exchange membranes with various ion-exchange capacities and thicknesses is investigated, and the impact of these properties on electrolyzer performance and short-term stability are discussed. The hydrocarbon anion exchange membrane. AF1-HNN8-50, having an ion exchange capacity of 2.1-2.5 meq OH- g(-1) and a thickness of 50 was able to achieve current densities of 2 A cm(-2) at a potential of 1.82 V using 1 M KOH at 60 degrees C.
