Abstract

An ETFE-(poly(ethylene-co-tetrafluoroethylene))-based radiationgrafted anion-exchange membrane (AEM) containing a butylspacer between the benzene and the methylpyrrolidinium groups (C4-AEM) had double the ex-situ alkali stability at 80 °C compared to a methylene benchmark (C1-AEM). H2/O2 fuel cells containing the C4-AEM still achieved a peak power density of > 1 W cm-2.
