KIST has carried out wide range of research and development in high-temperature solid oxide cells for energy conversion and storage applications including fuel cells and electrolysis. The ultimate goal of fuel cell research is to develop the high-performance, low-cost, modular, and fuel-flexible solid oxide fuel cells (SOFC) suitable for various power generation applications. We successfully demonstrated 1 kW-class stacks operating at 650oC using CH4 fuel based on conventional ceramic powder processing technologies. To further reduce the operating temperature without sacrificing the performance, application of thin film technologies such as pulsed laser deposition (PLD) and chemical solution deposition (CSD) are investigated. For energy storage, high-temperature solid oxide electrolysis cells (SOEC), which offer inherent advantages in thermodynamics and kinetics over the low-temperature conventional electrolysis, are being actively investigated for steam electrolysis, with a special focus on the long-term stability. The presentation will discuss the up-to-date progress of related research activities at KIST
