Cathodes are one of the key components of protonic ceramic fuel cells (PCFCs) requiring further development to enhance the performance of PCFCs. This encompasses the optimization of material compositions and microstructures, as well as a further understanding of the electrode processes. Here, a...

Compositionally engineered a La1-xBaxCoO3-δ-(1-a) BaZr0.9Y0.1O2.95 (a = 0.6, 0.7, 0.8 and x = 0.5, 0.6, 0.7) (LBZ) nanocomposite cathodes were prepared by oxidation driven in situ exsolution of a single-phase material deposited on a BaZr0.9Y0.1O2.95 electrolyte. The processing procedure of the...

La0.5Ba0.5CoO3-δ-BaZrO3 (LB-BZ)-based composite materials were prepared by a modified Pechini sol-gel method combined with exsolution. Two different LB-BZ composites were prepared through two alternative thermal treatments of the precursor gel. A metastable single phase with perovskite crystal...
