摘要

Sulfonated poly(phthalazinone ether ketone)s (SPPEKs) and zirconium hydrogen phosphate (ZrP) hybrid membranes for direct methanol fuel cells (DMFCs) were prepared by the impregnation method and direct blending method. The physicochemical properties of these hybrid membranes were studied by means of field-emission scanning electron microscope (FSEM), X-ray diffraction (XRD) analysis, and thermogravimetry analysis (TGA). For the hybrid membranes prepared from impregnation procedure, the highest proton conductivity could reach 0.074 S/cm at 80 degrees C under 100% relative humidity and the methanol permeability at room temperature is more than 10 times lower than that of Nafion 117.
