固体氧化物电解池电解水制氢效率影响因素数值分析
Numerical analysis of factors influencing efficiency of hydrogen production by solid oxide electrolysis of water
摘要
Abstract
The common hydrogen production technologies include alkaline water electrolysis,proton exchange membrane water electrolysis and solid oxide electrolysis.The electricity consumption,hydrogen production efficiency and energy utilization of SOEC(solid oxide electrolysis cell)is superior to the other two methods.Based on the theory of electrochemistry,thermodynamics and kinetics in the process of SOEC hydrogen production,the Aspen Plus software was used to establish the thermodynamic process model of SOEC water electrolysis hydrogen production system.The results were compared and verified with the documents.The effects of electrolysis temperature,pressure,cathode vapor content,anode air flow rate and current density on electrolysis voltage and hydrogen production efficiency were analyzed,and the optimum reaction conditions were obtained optimization under the condition of multi-factors.The research result can help enhance the electrolysis efficiency and energy utilization efficiency of SOEC electrolysis water hydrogen production system.关键词
