This paper describes an approach for high performance solid oxide fuel cells (SOFCs) based on the nano/microstructural control of the electrodes through the synthesis of nanocomposite particles. The LaxSr1-xMnO3(LSM)/Y0.15Zr0.85O1.93(YSZ) nanocomposite particles were successfully synthesized via a new co-precipitation method with nanocrystalline YSZ particles dispersed in an aqueous medium. The nanocomposite particles provide the uniform nanostructured cathode consisting of the grains of approximately 100 nm in diameter, and the SOFC with quite high performance at intermediate temperature (700-800 ℃). This paper also reports an approach for the atomic level control of nanocrystals, and describes its possibility to contribute for further performance enhancement of SOFCs.
