SULFONATE BASED COMPONUD AND POLYMER ELECTROLYTE MEMBRANE USING THE SAME

摘要

The present invention relates to: a sulfonate based-compound; a polymer electrolyte membrane using the same; a membrane electrode assembly including the same; and a fuel cell including the same. The present invention provides the sulfonate-based compound represented by Chemical Formula 1. In Chemical Formula 1, A1 to A4 are same with each other or different from each other and are independently halogen groups. The polymer electrolyte membrane manufactured by using the sulfonate-based compound easily forms a hydrophilic-hydrophobic phase separation structure.
