In this work, the performance of anion exchange membrane (AEM) electrolysis is evaluated. A parametric study is conducted, focusing on the effects of various operating parameters on the AEM efficiency. The following parameters-potassium hydroxide (KOH electrolyte concentration (0.5-2.0 M), electrolyte flow rate (1-9 mL/min), and operating temperature (30-60 °C)-were varied to understand their relationship to AEM performance. The performance of the electrolysis unit is measured by its hydrogen production and energy efficiency using the AEM electrolysis unit. Based on the findings, the operating parameters greatly influence the performance of AEM electrolysis. The highest hydrogen production was achieved with the operational parameters of 2.0 M electrolyte concentration, 60 °C operating temperature, and 9 mL/min electrolyte flow at 2.38 V applied voltage. Hydrogen production of 61.13 mL/min was achieved with an energy consumption of 48.25 kW·h/kg and an energy efficiency of 69.64%.
在这项工作中，对阴离子交换膜（AEM）电解的性能进行了评估。开展了一项参数研究，重点关注各种操作参数对AEM效率的影响。改变了以下参数——氢氧化钾（KOH）电解液浓度（0.5 - 2.0 M）、电解液流速（1 - 9 mL/min）和操作温度（30 - 60 °C）——以了解它们与AEM性能的关系。使用AEM电解装置，通过其产氢量和能量效率来衡量电解装置的性能。基于这些发现，操作参数对AEM电解的性能有很大影响。在施加电压为2.38 V时，电解液浓度为2.0 M、操作温度为60 °C、电解液流速为9 mL/min的操作参数下实现了最高产氢量。产氢量达到61.13 mL/min，能耗为48.25 kW·h/kg，能量效率为69.64%。
