英文摘要	interlayer-free la0.6sr0.4co0.2fe0.8o3-delta-ce0.8zr0.2o2-delta (lscf-cz) composite cathode on ysz electrolyte has been studied by using x-ray diffraction (xrd), scanning electron microscopy (sem) and electrochemical impedance spectra (eis). the addition of cz suppresses the formation of non-conductive srzro3 at the cathode and ysz electrolyte interface. as a result, the lscf-cz cell performance is greatly elevated. the lscf-cz cell exhibits 8.7 times higher current density than the lscf cell at 0.8 v and 600 degrees c. the incorporation of oxygen anion from lscf-cz cathode into ysz electrolyte is significantly accelerated. the stability of the lscf-cz cathode is remarkably improved as compared with the lscf cathode at 600 degrees c. copyright (c) 2015, hydrogen energy publications, llc. published by elsevier ltd. all rights reserved.
