Abstract

Abstract: Nitrogen-doped graphene oxide (N-doped GO), prepared by a facile hydrothermal reaction of GO with melamine as nitrogen source was studied as a filler in chitosan (CS) based anion exchange membranes (AEM) used in alkaline anion exchange membrane fuel cells. The structures and functional properties of the N-doped synthesized fillers (N level as high as 29.34 at.%) and produced CS-based AEMs were investigated by XPS, SEM, FTIR, XRD analysis, as well as, ion exchange capacity, tensile strength, ethanol permeability, alkali uptake, swelling ratio and cell performance tests. The as-obtained CS-based AEMs with 0.01 wt% N-doped GO filler have achieved a maximum power density of 149 ± 2.2 mW cm−2 at 80 °C, which is significantly higher than that of the benchmark commercial FAA Fumapem® and polybenzimidazole with values of 11 and 60 mW cm−2, respectively. The results demonstrate that the obtained membranes are promising AEM candidates for direct alkaline alcohol fuel cell applications. Graphic abstract: [Figure not available: see fulltext.].
