英文摘要	a quaternized poly(phthalazinone ether sulfone ketone) (qappesk) membrane doped with h3po4 was prepared and characterized. infrared and p-31 nmr spectra indicated that this membrane may have the same mode of conducting proton as polybenzimidazole (pbi) membrane doped with h3po4. the qappesk membrane doped with h3po4 showed high proton conductivity (0.072 s/cm at 150 degrees c), and good thermostability measured by thermogravimetric analysis. the peak power density of single cell with qappesk/h3po4 composite membrane and operated at 150 degrees c with dry h-2/o-2 reached 0.85 w/cm(2). these results show that qappesk/h3po4 composite membrane is promising for high-temperature proton exchange membrane fuel cell (pemfc) applications.
