Polybenzimidazole (PBI) high-performance membranes are fabricated from Repazole® PBI resin solutions. Leveraging exceptional processability, high-temperature resistance, and strong acid/alkali tolerance, these membranes maintain stable performance in operating environments exceeding 150°C and under strong acid/base conditions. They also enable composite fabrication with diverse materials, making them suitable for:

l High-temperature fuel cells and water electrolysis systems in hydrogen energy

l Vanadium redox flow batteries (VRFB) for emerging energy storage

l Electrochemical conversion of CO₂

l Gas separation and purification
