Resumo
The effects of alcohol used as solvent during the sol–gel synthesis of Nafion–SiO2 hybrid electrolytes have
been evaluated. The alcohol controls the distribution of silica particles in the phase separated structure
of Nafion and both the silica content and the water uptake of hybrid membranes are dependent on the
alcohol solvent. Thermal and structural properties inferred from differential scanning calorimetry and
small angleX-ray scattering were correlated with the enhanced water uptake and the proton conductivity
of hybrid membranes. Accordingly, fuel cell tests carried out at 130 ◦C and low humidity evidenced the
superior performance of Nafion–SiO2 hybrids.
