This study manufactured ETFE (Poly(ethylene-alt-tetrafluoroethylene) membrane for DMFC by means of electron beam radiation technology. The maximum degree of styrene-grafting existed at around 20kGy, giving around 100% degree for five hours of grafting at 45°C and 1.9meq/g of IEC (Nafion 115: 0.9meq/g). Electric power of ETFE membrane in DMFC was slightly lower than Nafion 115 membrane, whereas the MeOH crossover in ETFE membrane could be much more suppressed compared to Nafion 115.
Keywords. DMFC; ETFE; grafting; styrene; electron beam; crossover; electric power
