Polyvinyl chloride-sulfonated poly(styrene-co-acrylonitrile) [PVC-SP(ST-co-AN)] for proton exchange membrane fuel cell have been prepared through two steps. The first step was preparation of sulfonated poly(styrene-co-acrylonitrile) [SP(ST-co-AN)] by using solution polymerization and KPS as initiator and sulfonated the product of poly(styrene-co-acrylonitrile) [P(ST-co-AN)] which reacts with sulfuric acid. The second step was mixing polyvinyl chloride (PVC) and sulfonated poly(styrene-co-acrylonitrile) [SP(ST-co-AN)] with different ratio. Essential characters required for polyelectrolyte fuel cell membrane especially ionic conductivity, methanol permeability, ion exchange capacity (IEC), thermal stability and high mechanical properties were investigated. Ion exchange capacity increase with increase sulfonated poly(styrene-co-acrylonitrile) [SP(ST-co-AN)]. The methanol permeability of membrane which consider as essential character for PEM fuel cell application was found lower than of nafion. The obtained results are very promising and opening new area for conducting further investigations considering the very low price of polyvinyl chloride compared to nafion.
