Application of Sm0.5Sr0.5CoO3 - delta (SSC) cathode in solid oxide fuel cells (SOFCs) has its advantage of reducing polarization loss at intermediate operating temperatures (600-800 degrees C). However, the SSC cathode cannot be applied directly on yttria stabilized zirconia (YSZ) electrolyte due to the thermal mismatch and chemical reaction. In this work, Ce0.8Sm0.2O2 - delta (SDC) thin interlayers are fabricated between YSZ electrolyte layers and Sm0.5Sr0.5CoO3 - delta-SDC (SSC-SDC) cathode layers with dip-coating and pulsed laser deposition (PLD) methods. The 1400 degrees C-sintered SDC interlayer deposited by dip-coating method exhibits a porous microstructure. PLD technique yields a thin and dense SDC layer at a low substrate temperature of 600 degrees C and no additional peaks of (Zr, Ce)O-2-based solid-solution are present. Besides, the electrochemical performance of the YSZ/SDC (electrolyte/interlayer) fuel cell has a great improvement at intermediate operating temperature. (C) 2015 Elsevier B.V. All rights reserved.
