Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O 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.
