ION-CONDUCTIVE MATERIAL, SOLID POLYMER ELECTROLYTE MEMBRANE, AND FUEL BATTERY

摘要

This invention provides an ion-conductive material characterized by comprising an ion-conductive main component polymer and a polymer, with a lower glass transition temperature (Tg) than the main component polymer, added to the main component polymer, and a solid polymer fuel battery using the ion-conductive material. The above constitution can improve the ion conductivity of a solid polymer electrolyte from the viewpoint of molecular motion.
