In its most common configuration, a solid oxide fuel cell (SOFC) uses an oxygen‐ion conducting ceramic electrolyte membrane, perovskite cathode, and nickel cermet anode electrode. Cells operate in the 600–1000°C temperature range and utilize metallic or ceramic current collectors for cell‐to‐cell interconnection. Recent developments in engineered electrode architectures, component materials chemistry, cell and stack designs, and fabrication processes have led to significant improvements in the electrical performance and performance stability as well as reduction in the operating temperature of such cells. Large kW‐size power‐generation systems have been designed and field demonstrated. This paper reviews the status of SOFC power‐generation systems with emphasis on cell and stack component materials, electrode reactions, materials reactions, and corrosion processes.
