摘要：
Accommodation of huge amount of renewable power to be curtailed is a major problem for energy systems in China. Energy storage system is considered an efficient way to alleviate the problem. But conventional energy storage system is insufficient in dealing with long period energy storage demand of super large capacity. Electrolysis of water into hydrogen can meet the demand of large-scale storage capacity effectively, greatly broadening application field of abandoned renewable energy power. As efficiency of low-temperature electrolysis widely in research and promotion is relative low, the paper presents high-temperature solid oxide electrolysis cell (SOEC) for water electrolysis. Fundamental principles of SOEC are presented and its electrochemical mechanism leading to high efficiency of SOEC is elaborated from perspective of physical concepts. Based on a kW-scale experimental test platform, high efficiency of SOEC is verified. Key SOEC issues such as material, modeling and optimization control are discussed. Finally, SOEC prospect is analyzed from aspects of distributed energy and chemical applications. © 2017, Power System Technology Press. All right reserved.
