Abstract

The surface of Nafion membranes was modified to reduce methanol crossover by ion implantation with proton ions. The methanol crossover of ion-implanted Nafion membranes was reduced without influencing the other properties including the membrane properties. This simple process could offer advantages for direct methanol fuel cells at high methanol concentrations.
