Abstract
Anion-exchange membrane composed of chitosan (CS) and poly[(3-methyl-1-vinylimidazolium methyl sulfate)-co-(1-vinylcaprolactam)-co-(1- vinylpyrrolidone)] (PMVMS-co-VC-co-VP) was prepared by applying double cross-linking technique for alkaline membrane fuel cell (AMFC). Having tested the ion conductivity and water uptake without thermal cross-linking, the CS/PMVMS-co-VC-co-VP-OH- membrane (1:0.75 by mass) shows the ionic conductivity of 1.39 ž 10-3 S cm-1 with high water uptake of 88.45%. However, when the membrane was double cross-linked by both thermal and chemical cross-linking, the ionic conductivity of the membrane was improved and reached to 1.58ž10-3 S cm-1, instead, the water uptake of the membrane was largely decreased to lower than 48.02%. The oxidation stability of the membrane was also enhanced greatly. Moreover, the ionic conductivity increases as the temperature increased; with the maximum OH- conductivity of 3.85ž10-3 S cm-1 was obtained at 80oC.
