On the stability of anion exchange membrane fuel cells incorporating polyimidazolium ionene (Aemion+®) membranes and ionomers
We report the anion exchange membrane fuel cell (AEMFC) performance using commercial, polyimidazolium-based, Aemion+® as both the ionomer and membrane. Aemion+® affords reduced dimensional swelling yet higher water permeance compared to previously reported polybenzimidazolium-based Aemion® membranes...

| description | We report the anion exchange membrane fuel cell (AEMFC) performance using commercial, polyimidazolium-based, Aemion+® as both the ionomer and membrane. Aemion+® affords reduced dimensional swelling yet higher water permeance compared to previously reported polybenzimidazolium-based Aemion® membranes and ionomers. Non-reinforced Aemion+® is shown to enhance the properties of Aemion® membranes, and Aemion+® reinforced with a fluorine-free polyolefin substrate is shown to enhance the properties considered important to fuel cell operation with respect to non-reinforced analogues.

was obtained by using a direct membrane deposition (DMD) approach, where an ultrathin 5 μm membrane increased the voltage stability through enhanced water permeation, allowing characterization under these conditions.
