Nafion Nanofiber Mat In A Single Fuel Cell Test
Proton exchange membrane, PEM, was developed and tested for potential application in fuel cell. Nafion was
electrospun to nanofiber network with aid of poly(ethylene oxide), PEO, as a carrier polymer. The matrix polymer was
crosslinked with Norland Optical Adhesive 63 under UV after compaction and annealing. The welded nanofiber mat was
characterized for morphology, proton conductivity, and methanol permeability then tested in a single cell test station. The
results of the fabricated nanofiber membrane showed a proton conductivity of 0.10 S/cm at 25oC and higher fiber volume
fraction; methanol permeability of 3.6 x 10-6 cm2/s and power density of 96.1 and 81.2 mW/cm2 for 5 M and 1 M methanol
