- Abstract
- We herein report a thin film deposition of perovskite BaCo 0.4 Fe 0.4 Zr 0.1 Y 0.1 O 3-δ (BCFZY) by pulsed laser depositing (PLD) method for the use as a cathode in solid oxide fuel cells (SOFCs). The BCFZY powder was first synthesized via sol-gel method and pelletized to employ it as a target in PLD system. As a result, the PLD-deposited thin BCFZY film showed nano-porous morphology and preferred nano-architecture for cathode of SOFCs. The applicability of the thin film BCFZY to SOFC cathode was even confirmed by fabricating an SOFC with BCFZY cathode and operating it at 500 °C, where stable open-circuit voltage of 1.13 V was measured for an hour. © 2019 Elsevier B.V.
