Abstract

A new proton conducting perovskite material Sr3CaZr0.9Ta1.1O8.55 (SCZT) was synthesised and the mode of conduction elucidated through modelling. The changes in protonic conductivity underfuel cell conditions were examined using AC impedance techniques and a test fuel cell was constructed. The material proved less conductive than the standard BaCe0.95 Y0.05O2.975 material but was more stable under reformate conditions. The maximum power output generated by the SCZT85 cell was 0.2m/W/cm(2) at 600degreesC although this was for an electrolyte considerably thicker (1.5 mm) than would be used in an actual cell.
