%X A proton exchange membrane has been developed for
direct methanol fuel cell (DMFC). The nanofiber network composite
membranes were prepared by interconnected network of Nafion
(perfuorosulfonic acid) nanofibers that have been embedded in an
uncharged and inert polymer matrix, by electro-spinning. The
spinning solution of Nafion with a low concentration (1 wt%
compared to Nafion) of high molecular weight poly(ethylene oxide),
as a carrier polymer. The interconnected network of Nafion
nanofibers with average fiber diameter in the range of 160-700nm,
were used to make the membranes, with the nanofiber occupying up
to 85% of the membrane volume. The matrix polymer was
crosslinked with Norland Optical Adhesive 63 under UV. The
resulting membranes showed proton conductivity of 0.10 S/cm at
25°C and 80% RH; and methanol permeability of 3.6 x 10-6 cm2/s.
