Abstract

In this study, NiO-Ce0.8Sm0.2O1.9 (SDC) nanocomposite powders with NiO content of 40-60 mass% were successfully synthesized by hydroxide co-precipitation method. The effect of NiO content on crystal phase, crystallite size, average particle size and particle size distribution of the NiO-SDC nanocomposite powders was investigated. The average particle size of the NiO-SDC nanocomposite powders increased and the particle size distribution became wider with an increase in the NiO content. Anode-supported solid oxide fuel cells (SOFCs) were fabricated from the NiO-SDC nanocomposite powders with different NiO content and electrochemical performance was tested at 500-650 °C using humidified hydrogen as fuel. Results showed that the NiO-SDC nanocomposite powders were suitable to be applied as anode materials for low-temperature SOFCs. The anode-supported SOFC fabricated from the NiO-SDC nanocomposite powders with 50 mass% NiO demonstrated the highest electrical performance among the anode-supported SOFCs fabricated from the NiO-SDC nanocomposite powders with the NiO content of 40-60 mass%.
