Abstract 

Solid-oxide fuel cells (SOFCs) and proton ceramic fuel cells (PCFCs) offer a viable option to produce clean energy from sustainable resources, with low emission of pollutants, fuel flexibility and high energy conversion rates 1. New materials, which exhibit high ionic conductivity (≥ 10 mS cm-1) at intermediate temperatures (< 600 °C), are sought for the next generation of ceramic fuel cells. Such fuel cells will be more cost-effective and have greater longevity. Two new hexagonal perovskite systems will be presented which exhibit significant oxide and/or proton conductivity 2, 3. The structural features that control the ionic conductivity will be discussed.

Preliminary results on the novel hexagonal perovskite phase Ba3SrMo2O9 phase will also be presented. Electronic phase segregation is observed below 230 K followed by antiferromagnetic order at 30 K.
