Resumo
The present study reports on the performance enhancement of direct ethanol fuel cell (DEFC) at 130 C
with Nafion-titania composite electrolytes prepared by solegel technique and containing high volume
fractions of the ceramic phase. It is found that for high volume fractions of titania (>10 vol%) the ethanol
uptake of composites is largely reduced while the proton conductivity at high-temperatures is weakly
dependent on the titania content. Such tradeoff between alcohol uptake and conductivity resulted in a
boost of DEFC performance at high temperatures using Nafion-titania composites with high fraction of
the inorganic phase.
