A novel membrane for DMFC - Na2Ti3O7 Nanotubes/Nafion® composite membrane: Performances studies

► The novel composite membrane outperform pure Nafion® membranes under all the operating conditions in a DMFC. ► Under some operating conditions, the novel composite membranes even outperform Nafion®117, a much thicker membrane. ► Addition of Na2Ti3O7 nanotubes into Nafion® is an effective way to improve membrane performances in DMFC environments.
