제목 Sulfonated poly(arylene ether ketone) electrolyte membranes fof fuel cell application
초록 Composite membranes based on sulfonated poly(arylene ether ketone) (SPAEK) were fabricated by a solvent cast method. The brittleness of the SPAEK was compensated by introduction of organosiloxane polymer networks (OSPN). The sulfonated benzene silica mesoporous conductors (SMBS) maintain the water content at a high level, even at low relative humidity. Both OSPN and SMBS components enhance the proton conductivity of sPAEK membranes in a hydrated state, while maintaining the water uptake  below 55% even at 100℃. The SAXS patterns of the composite membranes explain the water-related membrane properties of membranes. The maximum power of the composite membrane based membrane-electrode assembly (MEA) was much higher than that of a Nafion-based oneat low relative humidities of 70% and 45%,, due to the capillary condensation effect of SMBS.
