Electrospinning of polysulphone to fabricate anion exchange membrane for cost-effective water electrolysis

Manufacturing cost-effective anion exchange membranes (AEMs) with high ionic conductivity, sufficient alkaline stability, and desired mechanical properties, is a new trend and still challenging. Here we represent the result of our trial to fabricate an intrinsic AEM by electrospinning mixed solution of polysulphone and Fumion® (a commercially available ionomer solution from Fuma-Tech, Germany) and its characterization for water electrolyzer application. The result is remarkable from a manufacturing perspective to create a new generation of active electrospun AEM for hydrogen production, although the ionic conductivity of these first prototypical samples will need to be improved in the future for end application, by increasing ionomer content.
