چكيده فارسي :
A proton-exchange membrane for a direct methanol fuel cell was prepared by modifying the chemical structure of poly (vinyl alcohol) (PVA) by means of sulfonation. The membrane was fabricated via crosslinking of poly (vinyl alcohol) by Glutaraldehyde (GA). The chemical structure and proton conductivity of the PVA and sulfonated PVA were studied by using FTIR and impedance spectroscopy. The proton conductivities of membranes were investigated as a function of sulfonation group content. Proton conductivity of PVA and the respected sulfonated membrane ranged between 2.8 ×10-8 to 0.096 S/cm.
