Barium zirconate (BaZrO₂) is a perovskite ceramic compound combining barium oxide with zirconium dioxide, known for its high-temperature stability and ionic conductivity. It is primarily investigated for solid-state electrolyte applications in fuel cells and electrochemical devices, where its proton-conducting properties at elevated temperatures make it attractive compared to yttria-stabilized zirconia (YSZ) for intermediate-temperature operation. The material remains largely in research and development phases, with potential to enable more efficient energy conversion systems in power generation and hydrogen technology applications.
