| 中文摘要 | La0.6Sr0.4Co0.2Fe0.8O3-delta (LSCF) precursor powder was prepared by a nitrate-glycine solution combustion method. The properties of LSCF powder were characterized by XRD, BET, FESEM, and dynamic laser scattering (DLS) method. The results showed that LSCF powder was in the perovskite structure with a specific surface area of 22.9 m(2) . g(-1) and an average particle size of 175 nm. The results of non-isothermal sintering tests suggested that LSCF powder possessed good low-temperature sintering activity. The cell Ni-YSZ/YSZ/LSCF (YSZ: yttria stabilized zirconia) with the cathode sintered at 800 degrees C for 2 h demonstrated excellent generation performance with the maximum power density of 0.97 W . cm(-2) and the power density of 0.83 W . cm(-2) at 0.7 V under operation at 700 degrees C. Low temperature processing of the interlayer-free LSCF cathode was beneficial to simplify the cell structure and manufacturing process and to improve the cell performance. |
