碱性水电解制氢系统稳态建模研究
Steady-State Modeling Study on Hydrogen Production by Alkaline Water Electrolysis
摘要
Abstract
As an efficient hydrogen production technology,alkaline electrolyzer holds significant application prospects in green hydrogen production.For alkaline water electrolysis hydrogen production systems,this paper proposes an accurate and applicable semi-theoretical and semi-empirical alkaline electrolyzer model based on electrochemical principles and thermodynamic analysis.This model treats the electrolyzer's cell voltage and gas purity as functions of operating pressure,temperature,and current density,and incorporates the influence of Faraday efficiency on hydrogen production rate.Based on literature-reported experimental data of a 50 m3/h alkaline electrolyzer under different operating conditions,this paper determines the model parameters via fitting using a nonlinear regression method.This paper further employs these experimental data to verify the model's accuracy and analyze its applicability under varying operating conditions.The simulation results show that the proposed model can effectively predict the electrolyzer's performance parameters,thereby providing a theoretical basis for the optimal design and the control systems of electrolyzers.关键词
