Porous La0.6Sr0.4CoO3-δ thin film cathodes for large area micro solid oxide fuel cell power generators
Abstract
<p>Porous La<sub>0.6</sub>Sr<sub>0.4</sub>CoO3-δ thin films were fabricated by pulsed laser deposition for being used as a cathode for micro solid oxide fuel cell applications as MEMS power generators. Symmetrical La<sub>0.6</sub>Sr<sub>0.4</sub>CoO<sub>3-δ</sub>/ yttria-stabilized zirconia/La<sub>0.6</sub>Sr<sub>0.4</sub>CoO<sub>3-δ</sub> free-standing membranes were fabricated using silicon as a substrate. A novel large-area membrane design based on grids of doped-silicon slabs was used. Thermomechanical stability of the tri-layer membranes was ensured in the intermediate range of temperatures up to 700 °C. In-plane conductivity of ca. 300 S cm<sup>-1</sup> was measured for the cathode within the whole range of application temperatures. Finally, area specific resistance values below 0.3 Ω cm<sup>2</sup> were measured for the cathode/electrolyte bi-layer at 700 °C in the exact final micro solid oxide fuel cell device configuration, thus presenting La<sub>0.6</sub>Sr<sub>0.4</sub>CoO3<sub>-δ</sub> as a good alternative for fabricating reliable micro solid oxide fuel cells for intermediate temperature applications.<br/> © 2013 Elsevier B.V.
