Novel anion exchange membranes based on pyridinium groups and fluoroacrylate for alkaline anion exchange membrane fuel cells

Novel fluorinated anion exchange membranes with pyridinium salt functionalized groups for alkaline anion exchange membrane fuel cells have been prepared and characterized. These membranes have shown a combination of good thermal stabilities, high ionic conductivities, and excellent chemical stabilities. The ionic conductivity of the membranes can be as high as 2.7 × 10−2 S cm−1 in deionized water at 30 °C. An alkaline H2/O2 fuel cell employing the resulting membrane was assembled and revealed a maximum power density of 124.8 mW cm−2 at 60 °C. The preliminary performances have demonstrated their potential as electrolytes for alkaline anion exchange membrane fuel cells.
