Abstract

Ba _0.5Sr _0.5Co _0.8Fe _0.2O _3-δ (BSCF) cathodes are prepared on NiO-yttria-stabilized zirconia (YSZ)/YSZ composite substrates using pulsed laser deposition (PLD) and the screen-printing method. The cathode by PLD outperforms that by screen-printing, with an enhancement of over 150% in the maximum power, which can be attributed to the PLD-enabled smaller internal resistance within the cathode and the reduced interfacial resistance between the cathode and the electrolyte.
