Microstructural Improvement of High-Temperature Solid Oxide Electrolysis Cells for High-Efficiency and High-Stability Carbon Dioxide Electrolysis

The research team, led by Professor Jongsup Hong from the Department of Mechanical Engineering (co-first author is Wooseok Lee) collaborated with Dr. Yoon Kyung-joong's team from KIST and Professor Lee Kang-taek's team from KAIST to improve the stability of solid oxide electrolysis cells (SOEC) that convert greenhouse gas carbon dioxide into high-value fuels. They solved the problem of carbon deposition caused by poor gas diffusion through improvement of the microstructure of the fuel electrode and elucidated the stability improvement mechanism based on FIB-SEM analysis and multi-physics computational analysis. This research has been published in Chemical Engineering Journal, a top-tier journal in the fields of thermal and reaction engineering (as of 2022, with an impact factor of 15.1, ranking in the top 3.2% in the JCR Engineering, Chemical section), recognizing its qualitative excellence.
