摘　　要：利用溶液浸渍法制备具有阴极与电解质一体化离子传导路径的纳米结构LSCF浸渍La10Si6027复合阴极,在此基础上,通过XRD和SEM研究阴极相结构、微观形貌等,并利用交流阻抗谱研究阴极的性能。结果表明,在700℃时,界面极化电阻为1.100Ω·cm2。The solution impregnation method was chosen for fabricating LSCF-La10Si6O27 composite cathode with continuous ion transportation from the cathode to the electrolyte by impregnation of LSCF-containing solution into porous La10Si6O27 structure presintered on the La10Si6027 electrolyte. The phase composition and microstructure of the cathode were investigated by XRD and SEM. The electrochemical performance of the composite cathode was determined by ac impedance spectroscopy. The electrode polarization resistance is 1.100 Ω·cm2 at 700 oC.
