| 摘 要： | 电解水与高效清洁一次能源耦合制氢,是理想的大规模制氢技术。该文建立了电解水制氢系统效率评估模型,并通过该模型对碱性、固体聚合物电解池(SPE)及固体氧化物电解池(SOEC)制氢系统总制氢效率进行了计算与分析。碱性制氢系统电解效率与总制氢效率均较低,分别为56%和25%;SPE制氢系统电解效率虽有提高约76%,但其总制氢效率仍较低约35%;而SOEC制氢系统电解效率可达90%以上,总制氢效率高达55%,分别是SPE与碱性制氢系统的1.5和2倍。高温气冷堆耦合的SOEC电解制氢系统是目前已知总制氢效率最高的大规模制氢系统。

| Abstract: | Water electrolysis coupled with an efficient and clean primary energy source is an ideal large-scale hydrogen production technology.A model was developed to predict the efficiency of a water electrolysis system for hydrogen production based on the overall efficiency of an alkaline electrolysis system,a solid polymer electrolyte(SPE) system,and a solid oxide electrolysis cell(SOEC) system.The results show that both the electrolysis efficiency,56%,and the overall efficiency,25%,are very low.The electrolysis e... |
