In the present work proton exchange membranes were synthesized from the blend between unsaturated polyester resin and natural rubber. This polymer blend was vulcanized and loaded with titanium dioxide. The membranes prepared were characterized by evaluating water uptake, ion exchange capacity and tensile strength . Both, vulcanization and introduction of charge increase the water uptake and ion exchange capacity of polymeric membrane , however, vulcanized membranes show better water uptake (15.96%) and ion exchange (0.1210 meq/g ) than charged with titanium and u nmodified membranes . The blend prepared was proved to be suitable for fuel cells, since it exhibits Young’s modulus and maximum strain higher than Nafion® commercial membranes. The results obtained suggest high potential for the application as proton excha nge membrane for fuel cells.
