An important question of LSGM-based SOFC was formation of resistive phases at anode/electrolyte interface as a result of solid-state reactions.The key issue was preparation of a thin and dense La-doped ceria La_(0.3)Ce_(0.7)O_(2-δ)(LDC30) as an interlayer between anode and electrolyte.In this paper the LDC30 precursors was prepared by co-precipitation method.After calcined it was found that only the fine pure phased LDC30 powder was formed due to adulteration into CeO_2 crystal lattice successfully by X-ray diffractometer(XRD) and particles distribution testing,and the optimum parameters were obtained sintering at 1000℃ with 2h holding time.The LDC30 slurry were coated on LSGM electrolyte by screen-printing,and then sintered at different temperature.The influences of sintering temperature on the microstructure and performance of LDC films were investigated using SEM and thermal expansive analysis;The results of investigation show that optimum parameters were obtained firing at 1400℃ with 2h holding time and a dense interlayer of 10 μm thickness was obtained under this condition,and the power density of cells with interlayer was increased by 44% compared with that without interlayer.
