我们报告使用的全烃阴离子交换膜能够实现高电流密度，通过优化MEA的制造和操作条件。研究了具有不同离子交换容量和厚度的市售Aemion（TM）阴离子交换膜的电化学行为，并讨论了这些性质对电解槽性能和短期稳定性的影响。碳氢化合物阴离子交换膜。AF 1-HNN 8 -50的离子交换容量为2.1- 2. 5 meqOH-g（-1），厚度为50 μ m，在60 ℃下使用1 M KOH在1.82V的电位下能够实现2Acm（-2）的电流密度。
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.
