碱性水电解槽反向电流现象产生的原理与改进策略
MECHANISM AND IMPROVEMENT STRATEGY OF REVERSE CURRENT PHENOMENON IN ALKALINE WATER ELECTROLYZER
摘要
Abstract
With the increasing global demand for renewable energy,alkaline water electrolysis hydrogen production systems have become a focus of research and application due to their low cost and large-scale hydrogen production potential.However,when the alkaline water electrolyzer is shut down or the load fluctuates,reverse current will be generated,which will cause irreversible phase transition of the catalyst on the electrode surface inside the electrolyzer,affecting the long-term stability and efficient operation of the electrolyzer.This paper first introduces the principle of reverse current generation,and then provides a detailed overview of three common strategies for reducing reverse current:electrocatalytic material optimization,system structure optimization,and system operating parameter optimization.The advantages and disadvantages of the three strategies are compared.In the future,the improvement of reverse current in alkaline water electrolyzer should be combined with these three strategies to achieve a more stable and efficient alkaline water electrolysis hydrogen production system.关键词
