BaZrO3
semiconductorBaZrO3 is a ceramic perovskite compound combining barium, zirconium, and oxygen, belonging to the family of mixed-metal oxides with a cubic crystal structure. It is primarily investigated as a proton-conducting electrolyte material for solid oxide fuel cells (SOFCs) and hydrogen separation membranes, where its ability to conduct protons at elevated temperatures makes it an alternative to traditional yttria-stabilized zirconia (YSZ). Engineers consider BaZrO3 when designing energy conversion systems that demand high ionic conductivity at intermediate operating temperatures (500–700 °C), offering potential advantages in efficiency and material compatibility compared to conventional oxygen-ion conductors, though it remains largely in research and early commercialization phases.
