摘要：

Performance of LaNi1-xCoxO3-delta (LNC) (x=0.4 to 0.7) as a cathode in solid oxide fuel cell (SOFC) is evaluated. Symmetrical cathode/electrolyte/cathode cells for electrochemical testing are prepared by infiltration of yttria stabilized zirconia (YSZ) backbone with LNC solutions. It is showed that the cathode infiltrated with LaNi0.5Co0.5O3-delta (LNC155) has the lowest polarization resistance and activation energy, 197 m Omega cm(2) at 600 degrees C and 0.91 eV, respectively. Therefore it is the most promising material of the LNC group for electrochemical applications. X-ray diffraction analysis revealed that none of the materials is single-phased after heat treatment at 800 degrees C as they contain residues of La2O3 and La2NiO4-delta.
