Properties of Pr and In-doped BaZrCeY-based electrolyte for Proton Conducting Fuel Cell systems

Abstract Proton conducting oxides are potential electrolyte candidates for intermediate-temperature solid oxide fuel cell (SOFC) because of their attractive advantages such as excellent ionic conductivity and moderate activation energy for proton transfer. At present, many investigated protons conducting oxides are BaCeO 3 and BaZrO 3 -based materials. In this study, BaCeZrY-based electrolyte doped with Pr and In was synthesised by microwave-assisted glycine nitrate process. The synthesised powders showed a single cubic perovskite phase without any additional phases and thus have potential application in Proton Conducting Fuel Cell systems.
