- Abstract
- Composite Nafion-based membranes, containing 5 wt % of high-purity mesoporous titania with an average pore size of about 3.5
nm heated to 350, 450, and 600°C as a filler were successfully recasted. Field emission scanning electron microscopy observations
showed a high degree of dispersion of mesoporous titania particles in Nafion. Direct methanol fuel cell investigation of such
membranes at temperatures higher than 100°C revealed a considerable influence of the presence of the ceramic oxide and of its
specific surface area on the electrochemical behavior. The composite membranes allowed operation up to 145°C, showing a
significant performance improvement with respect to pure Nafion. At 145°C with oxygen feed, a power density of about
335 mW/cm2 was recorded for the composite Nafion-based membranes, containing 5 wt % of mesoporous titania calcined at
450°C. (literal)
