AbstractInterlayer-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.
