Figure 1. Schematic Illustration of a New Family of Proton-Conducting Materials

Caption

We report Ba5Er2Al2ZrO13, a hexagonal perovskite-related oxide as a new class of proton conductors exhibiting higher conductivities than 10?3 S cm?1 between 300 and 1200°C. A new structure family of proton conductors with the inherently oxygen-deficient h? layer offers a strategy in designing superior proton conductors based on hexagonal perovskite-related oxides.
