Synergistic role of graphene oxide-magnetite nanofillers contribution on ionic conductivity and permeability for polybenzimidazole membrane electrolytes
Efficient nanofillers within polymeric electrolytes are an interesting design for constructing high-performance membranes for direct methanol alkaline fuel cells. In this work magnetite (Fe3O4) particles are synthesized onto graphene oxide (GO) nanofillers and incorporating into a polybenzimidazole (PBI) matrix for membrane formation. The Fe3O4 nanoparticles are simultaneously anchored onto GO carbon basal planes to form GO-Fe3O4 via the solvothermal process. The pristine PBI, PBI/GO, PBI/Fe3O4, and PBI/GO-Fe3O4 composites are formulated and doped with potassium hydroxide solution to form ionic conductors. GO nanofillers suppress the methanol permeation rate in PBI/GO-Fe3O4 composite membranes while the anchored Fe3O4 nanoparticles result in a bumpy surface, reducing chain packing and promoting anionic conductivity via the loose polymeric free volume. Therefore, the conductivity-to-permeability selectivity of PBI/GO-Fe3O4 composite membrane is improved three times than other samples. The maximum peak power density (Pmax) of a fuel cell employing the PBI/GO-Fe3O4 composite membrane achieves 233 mW cm?2 at 80 C. The superior power output is attributed to the combined effect of the enhanced anionic conduction resulting from anchored GO-Fe3O4 particles’ steric hindrance on polymer chains to enlarged ion diffusion pathways, and the reduced methanol cross-over from the GO’s high aspect ratio to retard molecular permeation in the composite membrane.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 17057-04-4
