Orion CMX anion exchange membrane has an ion exchange capacity greater than 2.2 mequiv/g and hydroxide anion conductivity of 140 mS/cm at 80 deg C. The blind study conducted by NREL demonstrated that AEMs manufactured with Orion's proprietary resin will provide exceptional lifetime at high temperatures without any degradation (>1000 hours of durability at 80 °C with 1M KOH electrolyte).
