The present invention relates to a sulfonated poly polymer electrolyte membrane containing a metal(Ce,Co,Fe) phthalocyanine and a process for producing the same. A series of uncapped copolymers were synthesized using this bisphenol. The copolymers synthesized had high glass transition temperature and exhibited good thermal stability. More specifically, it is a polymer electrolyte membrane having excellent membrane durability, low water absorption in aqueous solution, and high proton conductivity.Relates to an electrolyte membrane and a polymer electrolyte fuel cell, and a hybrid membrane made of a sulfonated poly (ether sulfone) containing a metal phthalocyanine has excellent water absorption and proton conductivity despite relatively low ion exchange capacity.In addition, the hybrid membrane not only has excellent membrane durability but also plays an important role a proton conduction promoter and can be used as an electrolyte membrane of a fuel cell.
