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 comp...

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 catho...

Hydrogen production from water electrolysis is a key enabling energy storage technology for the large-scale deployment of intermittent renewable energy sources. Proton ceramic electrolysers (PCEs) can produce dry pressurized hydrogen directly from steam, avoiding major parts of cost-driving downstre...

Membranes for selective carbon dioxide permeation are likely to be important devices in future separation processes relevant to the energy industry. Here we review the current state of research into a particular class of carbon dioxide permeable membrane: the supported molten-salt membrane. Such mem...

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 struc...
