The paper reports on the processing of chitosan N-doped reduced graphene oxide (CS/N-rGO) nanocomposite membranes prepared by a facile, dispersion-casting procedure aimed as anion exchange membranes in fuel cells. Genipin (GEN) was used as a crosslinking agent to ameliorate mechanical weakens of nanocomposite membranes, while the N-rGO filler, aside of its role as a mechanical enhancer, is expected to improve the ionic conductivity of membranes. The resulting properties of processed membranes in terms of morphology, tensile strength, elasticity, and ethanol permeability were examined. The relevance of the membranes in terms of efficiency and performance was demonstrated in a single cell test.
