Abstract
In this work, an styrene-acrylic ester copolymer resin was used to synthesize proton exchange membranes for its application in fuel cells. The properties of these membranes were modified by the sulfonation reaction at different times. Furthermore, the water uptake, ion exchange capacity and mechanical properties were measured. Sulfonated membrane during 3 h exhibited high water uptake and proton exchange, 38.10% and 0.24 meq/g, respectively; while unmodified membranes exhibits low water uptake and proton exchange, 16.08% and 0.1 meq/g respectively. Moreover, elasticity of the membrane increases with increasing the sulfonation reaction time due to the introduction of sulfonic groups into the polymer chain. The properties of membranes confirm the possibility of its use as a proton exchange membrane.
