Abstract

Abstract This paper reports our current material research and development for advanced intermediate temperature (IT, 400–700 °C) solid oxide fuel cells (SOFCs). The materials reported in this work are based on ceria–salt-composites, which have super function, e.g. displaying ionic conductivity of 0.01–1 S cm −1 in the IT region. They are functional ceramic materials for advanced ITSOFC applications. When these new composites are used as ITSOFC electrolytes, a performance of 300–800 mW cm −2 between 400 and 650 °C has been demonstrated.
