La0.4Sr0.6Co0.2Fe0.7Nb0.1O3-δ (LSCFN) anode structure, electrochemical performance and operating stability are characterized using CO-CO2 mixed as fuel. Results show that, the ABO3 perovskite structure of LSCFN is reduced to A2BO4 Ruddlesden-popper structure in CO fuel. While, the addition of CO2 can shift the structure of LSCFN back to single perovskite, and inhibit coking effectively. The maximum output power density of single cell using pure CO fuel is 0.6 W/cm2 at 850℃. And the cell operates for more than 100 hours when using CO∶CO2 mixed gas as fuel in molar ratio of 5∶1.
