In and ex situ characterization of an anion-exchange membrane for alkaline direct methanol fuel cell (ADMFC)

► Diffusion of OH− ions is slower through FAA-2 membrane compared to water molecules. ► Permeability of methanol is low through FAA-2 membrane. ► FAA-2 membrane is suitable for MEA heat pressing. ► Concentrated methanol solution could be used with alkaline DMFC.
