摘要：

Ce-doped La0.4Sr0.5Ba0.1TiO3-delta (LCSBT) perovskite anode catalysts in solid oxide fuel cells were successfully synthesized by a modified rheological phase reaction for the first time. Pure LCSBT could be obtained under a reducing atmosphere and nano-CeO2 particles could be exsoluted from LCSBT after being sintered in air. The catalytic activity and electrochemical performance of LCSBT anodes for the H-2 oxidation were obviously improved comparing with the pure La0.4Sr0.5Ba0.1TiO3-delta (LSBT) and LSBT&CeO2 admixture anodes. The improved performance could be attributed to the nanostructure of LCSBT and the exsoluted nano-CeO2 particles. (c) 2014 Elsevier B.V. All rights reserved.
