Sulfonated poly(arylene ether ketone) ( SPAEK) with pendant carbonxylic acid group was synthesized. The pendant carbonxylic acids were transformed to phosphoric acid group in order to increase proton conductivity of SPAEK membranes, ehancing application ability of proton exchange membrane in fuel cell. The chemical structure will check Nuclear Magnetic Resonance ( NMR) and Fourier transform infrared spectroscopy (FTIR). Properties of membrane such as water uptake, cluster size, methanol permeability, thermal and mechnical stability especially proton conductivity will be studied at different temperature. |
