Investigation of a direct methanol fuel cell based on a composite Nafion®-silica electrolyte for high temperature operation

Abstract Operation of a liquid-fed Direct Methanol Fuel Cell (DMFC) working at 145°C was demonstrated by using a composite membrane made of Nafion ® ionomer and silica. The enhanced humidification conditions of the membrane–electrode (ME the measured methanol cross-over rate was 4×10 −6 moles min −1 cm −2 . A physico-chemical characterization of the cell components is also reported.
