实验研究了电解液种类和浓度对阴离子交换膜（AEM）水电解性能的影响。当将氢氧化钾（KOH）或碳酸钾（K2CO3）溶液用作电解液时，在温和的碱性条件下电解是成功的，而由于AEM的高电阻，用纯水电解是相当困难的。即使在相似的pH值（约12）下，使用K2CO3溶液的AEM电解性能也上级使用KOH溶液的AEM电解性能。在电解过程中还测量阳极气体室中的氢含量和所产生的氢的相对湿度。(C)2018年氢能出版有限责任公司。由爱思唯尔有限公司出版。保留所有权利。
The effect of species and concentration of electrolytic solution on the performance of anion exchange membrane (AEM) water electrolysis is experimentally examined. When potassium hydroxide (KOH) or potassium carbonate (K2CO3) solution is applied for the electrolytic solution, electrolysis is successful under mild alkaline conditions, whereas electrolysis with pure water is quite difficult due to the high resistance of the AEM. AEM electrolysis performance with K2CO3 solution is superior to that with KOH solution, even at similar pH of around 12. Hydrogen content in the anode gas compartment and relative humidity of produced hydrogen are also measured during the electrolysis. (C) 2018 Hydrogen Energy Publications LLC.
