A highly durable cross-linked hydroxide ion conducting pore-filling membrane†
Abstract
A highly durable, anion exchange membrane with a uniform thickness of 23.4 μm was fabricated by the pore-filling approach in a porous substrate. The resulting membrane has a hydroxide conductivity in excess of 40 mS cm−1 at 20 °C and does not exhibit significant changes in ion conductivity and IEC in 5 M solution of NaOH at 50 °C for 1500 h.
