Polymer electrolyte membrane fuel cells (PEMFC) are considered as prospective energy conversion systems because of high efficiency and environmental advantage. However, the current PEMFC technology uses commercialized perfluorosulfonic acid (PFSA) polymers as a proton exchange membrane, which has the issues of high production cost, poor recyclability at intermediate temperature. In this study, We have synthesized a non-fluorinated hydrocarbon membrane. Also, non-fluorinated membrane has a symmetric chemical structure and sulfonated block copolymer was prepared and characterized using 1H-NMR, and the proton conductivity, ion exchange capacity (IEC), and water uptake. properties were evaluated. The synthesis, characteristic and fuel cell performance and newly prepared membrane will be discussed.
