摘要

聚合物电解质膜（PEM）电解槽或碱性电解槽需要使用可再生能源如风能和/或太阳能来生产绿色氢气。PEM和碱性电解槽在很多方面不同，即时基本材料、系统配置和操作特性也不同。紧紧抓住每种电解槽的特点，构建一个优化的水解水系统，对构建安全的氢气生态系统和提高绿色氢气生产效率有很大帮助。本文介绍了自行研制的千瓦级碱水电解槽的基本运行特点和水电解效率。最后，简要概述了PEM和碱性电解槽在大容量绿色制氢系统中的特点。

Operational Characteristics of High-Performance kW class Alkaline Electrolyzer Stack for Green Hydrogen Production

Polymer electrolyte membrane (PEM) electrolyzer or alkaline electrolyzer is required to produce green hydrogen using renewable energy such as wind and/or solar power. PEM and alkaline electrolyzer differ in many ways, instantly basic materials, system configuration, and operation characteristics are different. Building an optimal water hydrolysis system by closely grasping the characteristics of each type of electrolyzer is of great help in building a safe hydrogen ecosystem as well as the efficiency of green hydrogen production. In this study, the basic operation characteristics of a kW class alkaline water electrolyzer we developed, and water electrolysis efficiency are described. Finally, a brief overview of the characteristics of PEM and alkaline electrolyzer for large-capacity green hydrogen production system will be outlined.
