Abstract

Abstract : Two novel cross-linked anion exchange membranes (AEMs) composed of PVA or Chitosan by incorporation of PMViC-Co-VP as ion conductors for alkaline fuel cells (AFCs) were prepared by a simple solution-casting method. The anion conductivity (OH - ) and water uptake of the as-prepared membranes were investigated. It is found that the OH - conductivities could reach 0.0086S cm -1 for both PVA/PMViC-Co-VP/GA and Chitosan/PMViC-Co-VP/GA membranes, and gradually increased with increasing temperature up to 80 o C. Meamnwhile, the water uptake ( WU ) of these two kinds membranes are aslo less than 100% after immerion in different concentrations of KOH (1-8M) solution. In addition, both PVA (Chitosan)/PMViC-Co-VP/GA membranes posses good mechanical property, where the PVA/PMViC-Co-VP/GA (1:0.5:0.1 by mass) membrane shows the tensile strength of 31.11 MPa with elongation at break of 10.45%.
