Primary Application
This precision-engineered zirconia powder is specifically designed for manufacturing composite membranes in alkaline water electrolysis (AWE) systems. It serves as a key hydrophilic filler in membranes, where it：
•Enhances Ionic Conductivity: Facilitates efficient OH⁻ transport, reducing membrane resistance (target area-specific resistance <0.5 Ω/cm²).
• Improves Gas Barrier Properties: Prevents H₂/O₂ crossover, ensuring high gas purity and operational safety.
• Boosts Mechanical Strength: Reinforces membrane durability (wet tensile strength >20 N/mm²) through uniform dispersion in polymer matrices (e.g., polysulfone, PPS)
