Crosslinked sulfonated poly(vinyl alcohol)/sulfonated multi-walled carbon nanotubes nanocomposite membranes for direct methanol fuel cells

► We synthesized sulfonated PVA/sulfonated MWNTs nanocomposite membranes. ► The methanol permeability of the this membranes were remarkably lower than Nafion. ► These membranes showed higher proton conductivity from 0.032 to 0.075 S/cm. Organic/inorganic membranes based on sulfonated poly(vinyl alco...
