Abstract

Dense La0.9Sr0.1Ga0.8Mg 0.2O3-δ (LSGM, 5 μm in thickness)/Ce 0.8Sm0.2O2-δ (SDC, 400 nm in thickness) bilayer films were deposited on a dense NiO (Fe3O4)-SDC anode substrate by a pulsed laser deposition (PLD) method. After in-situ reduction, the substrate turned to be porous and it can be used as a porous anode substrate. The power density was strongly affected by the oxide ion conductor combined with LSGM and it was found that SDC is the most useful for achieving the high power density. Preparation of Sm0.5Sr 0.5CoO3 cathode film by PLD method is also studied for decreasing the contact resistance of cathode. Preparation of SSC film by PLD is effective for decreasing cathodic overpotential and 400 nm thick film is the most effective for achieving the high power density. At 773 K, the maximum power density of the cell becomes higher than 500 mW/cm2.
