Direct methanol fuel cell (DMFC) performance is limited by methanol permeation through Nafion membranes and interfacial resistances between membrane electrode assembly (MEA) layers. An analysis of several membrane systems showed that Nafion impregnated with Silica nanoparticles and bilayer membranes incorporating two equivalent weights of Nafion exhibited the most favorable balance between protonic conductivity and methanol crossover at high methanol concentrations. In terms of MEA fabrication, spraying catalyst directly on the membrane achieved closest contact between the membrane and catalyst.
