Recently, Perovskite oxides have been widely used in electrochemical conversion devices like Proton conducting Ceramic Fuel Cells (PCFC). Among them, barium zirconate (BaZrO3) is considered as a promising PCFC electrolyte material due to its excellent chemical stability and rapid proton diffusion. By altering the synthesis parameters and conditions, various novel synthesis techniques have been employed to prepare barium zirconate (BaZrO3) with enhanced material properties. Doping with trivalent impurities improves proton mobility and increases proton conductivity at reduced temperature, thereby expanding the scope of PCFC application with optimized output performance.
Recently, Perovskite oxides have become the primal components for the establishment of electrochemical con-version device like Proton conducting Ceramic Fuel Cells (PCFC). Owing to the excellent chemical stability and rapid proton diffusion, barium zirconate (BaZrO3) is acknowledged as the emerging PCFC electrolyte material. Nanoionics envisions the distinct features, behaviour, and efficiency of the material and endorses its chemical reactivity and electrical property against harsh environment with enlarged surface area and quantum effect. To enhance the material property, barium zirconate (BaZrO3) has been prepared by different novel synthesis techniques altering the synthesis parameters and conditions. Dopant incorporation into pristine BaZrO3 accel-erate the mobility of protons and increases the proton conductivity at reduced temperature (600-700 degrees C). This featured article demonstrates the elemental properties, synthesis methods and the role of trivalent dopant im-purities which helps to expand the scope of PCFC application with optimized output performance.
