Ce-doped La0.7Sr0.3Fe0.5Cr0.5O3-delta (Ce-LSFC) perovskite anode catalysts for solid oxide fuel cells are successfully synthesized by a modified combustion method for the first time. The pure perovskite structure without formation of CeO2 is obtained when the content of Ce <= 10%. Compared with La0.7Sr0.3Fe0.5Cr0.5O3-delta anode, Ce-LSFC anode not only shows much higher catalytic activity towards the oxidation of syngas with less carbon deposition, but also displays better regeneration from coking. The enhanced performance is attributed to the more available oxygen vacancies in lattice and better oxygen mobility after doping with Ce. (C) 2014 Elsevier B.V. All rights reserved.
