Abstract
In terms of large-scale green hydrogen production,alkaline water electrolysis hydrogen production is a relatively mature technology.Modeling alkaline water electrolysis hydrogen production equipment is an effective tool for understanding,analyzing,and optimizing the alkaline water electrolysis hydrogen production process and related equipment.Although there are various models for studying alkaline water electrolysis hydrogen production equipment,there is a lack of summary of the current development status and existing problems of the models.This paper provides a review of the research progress on the model of alkaline water electrolysis hydrogen production equipment.Firstly,three main water electrolysis hydrogen production technologies are compared,and the working principle of the electrolytic cell used in the alkaline water electrolysis hydrogen production equipment is introduced.Then,the models based on the alkaline water electrolysis hydrogen production equipment are summarized from the perspectives of steady-state and dynamic models.Finally,the research and development status of the components of the alkaline water electrolysis hydrogen production equipment is introduced.The research results show that:1)Three main water electrolysis hydrogen production technologies are alkaline water electrolysis hydrogen production,proton exchange membrane water electrolysis hydrogen production,and solid oxide water electrolysis hydrogen production.2)At present,the hydrogen production efficiency of the electrolytic cells used in commercial alkaline water electrolysis hydrogen production devices ranges from 59%to 70%.Many studies have focused on improving the hydrogen production efficiency by changing the operating conditions of the electrolytic cells and innovating their related components.3)The steady-state model of alkaline water electrolysis hydrogen production equipment mainly includes thermodynamic model and electrochemical model;The dynamic model of alkaline water electrolysis hydrogen production equipment generally includes gas purity model and thermal model.The research results can provide theoretical and technical support for further improving the modeling of alkaline water electrolysis hydrogen production equipment.关键词
