AB The efficiency of solid oxide fuel cell cathodes can be improved by microstructuraloptimization and using active layers, such as doped bismuth oxides. In this work, Bi1.5Y0.5O3 (BYO)films are prepared by spray-pyrolysis deposition at reduced temperatures on a Zr0.84Y0.16O1.92 (YSZ)electrolyte. The influence of the BYO film on the performance of an La0.8Sr0.2MnO3 (LSM) cathodeprepared by traditional screen-printing and spray-pyrolysis is investigated. A complete structural,morphological, and electrochemical characterization is carried out by X-ray di raction, electronmicroscopy, and impedance spectroscopy. The incorporation of BYO films decreases the Area SpecificResistance (ASR) of screen-printed cathodes from 6.4 to 2.2 W cm2 at 650  C. However, furtherimprovements are observed for the nanostructured electrodes prepared by spray-pyrolysis withASRs of 0.55 and 1.15 W cm2 at 650  C for cathodes with and without an active layer, respectively.These results demonstrate that microstructural control using optimized fabrication methods isdesirable to obtain high-e ciency electrodes for solid oxide fuel cell (SOFC) applications.
