Abstract : Novel proton exchange membranes (PEMs) were investigated that show potentialfor operating at higher temperatures in both direct methanol (DMFC) and H2/air PEMfuel cells. The need for thermally stable polymers immediately suggests the possibility ofheterocyclic polymers bearing appropriate ion conducting sites. Accordingly, monomersand random disulfonated poly(arylene ether) copolymers containing either naphthalimide,benzoxazole or benzimidazole moieties were synthesized via direct copolymerization.The ion exchange capacity (IEC) was varied by simply changing the ratio of disulfonatedmonomer to nonsulfonated monomer in the copolymerization step.
