Abstract [en]

This paper reports our current material research and development for advanced intermediate temperature (IT, 400-700 degreesC) 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 degreesC has been demonstrated.
