POLYMER ELECTROLYTE MEMBRANE OF METALLOPHTHALOCYANINE CONTAINED SULFONATED POLY(ETHER SULFONE)S AND PREPARING METHOD THEREOF

摘要

The present invention relates to a sulfonated poly(ether sulfone) polymer electrolyte membrane including metallophthalocyanine and a preparing method thereof. More specifically, the present invention relates to a polymer having an excellent membrane durability, a low moisture absorptivity in an aqueous solution, and a high proton conductivity; a manufacturing method thereof; an electrolyte membrane based on the polymer; and a polymer electrolyte membrane fuel cell using the same. The hybrid membrane made of sulfonated poly(ether sulfone) including metallophthalocyanine according to the present invention has excellent moisture absorptivity and proton conductivity despite a relatively low ion exchange capacity (IEC). Also, the hybrid membrane can be used for the electrolyte membrane of a fuel cell because the hybrid membrane has excellent membrane durability and plays an important role as an antioxidant and an ion conductivity accelerator.
