Processing and characterisation of BaZr0.8Y0.2O3−δ proton conductor densified at 1200 °C

Abstract

BaZr0.8Y0.2O3−δ densifies at 1200 °C on employing a combination of Ba excess, ZnO sintering additive and nanopowders prepared by a sol–gel route. The low densification temperature decreases grain-boundary resistance despite the lower grain size.
