Light gray-buff powder. Insoluble in water and alkalies; slightly soluble in acid. | [Application]
Barium zirconate proton exchange membrane fuel cells and electrolyzer cells exhibit outstanding electrochemical performance and stability. They demonstrate high Faraday efficiency and exceptional stability within a temperature range of 450 to 600 degrees Celsius, under water vapor partial pressures of 0.5 to 0.7 atmospheres, and at high electrolyzer current densities of 0.5 to 2.0 amperes per square centimeter. These properties confer significant advantages over conventional barium cerate electrolytes.
