Barium zirconate (BaZrO₃) is a ceramic compound belonging to the perovskite family, known for its high thermal stability and ionic conductivity properties. It is primarily investigated for advanced energy and electrochemical applications, particularly as a proton-conducting electrolyte material in fuel cells and hydrogen separation membranes operating at intermediate temperatures. BaZrO₃ offers advantages over traditional yttria-stabilized zirconia in certain high-temperature electrochemical systems due to its enhanced chemical stability in reducing and steam-containing atmospheres, making it valuable for next-generation clean energy technologies.
