Nafion membranes with vertically-aligned CNTs for mixed proton and electron conduction

▸ Fabricated vertically-aligned CNTs and nafion membranes. ▸ Such membranes allow for mixed proton and electron conduction. ▸ Results are compared to nafion and CNTs nanocomposites fabricated for the same aim. ▸ Electron and proton conductivities are improved with respect to the previous work.
