La0.4Sr0.6Co0.2Fe0.7Nb0.1O3-δ(LSCFN)，a perovskite oxide materials, have been synthesized by the solid state reaction method .The electrolyte-supported symmetrical solid oxide fuel cells were fabricated by tape-casting and screen-printing procedure using YSZ as electrolyte, GDC as interlayer and LSCFN as both anode and cathode. The crystal structure and chemical stability were examined by X-ray diffraction (XRD) and microstructure was inspected by scanning electron microscopy (SEM). The electrical properties of single cell were tested by using humidified 3% H2 and CH4 as fuel respectively, ambient air as oxidant and tested the stability in humidified 3% CH4 at 850℃.The results show that LSCFN appeared to be chemically compatible with GDC to at least 1400℃. The maximum power density was 254 mW cm-2 and 105 mW cm-2 in humidified H2 and CH4 at 850℃, respectively. Stable performance was sustained for at least for 100 h operating in humidified CH4. These results suggest that the LSCFN can potentially serve as an electrode for symmetrical SOFCs with YSZ electrolyte.
