PROTON-CONDUCTIVE MEMBRANE, METHOD FOR PRO DUCTING THE SAME, AND FUEL CELL USING THE SAME

摘要

PURPOSE: Provided are a proton (hydrogen ion)-conducting membrane which is excellent in resistance to heat, durability, dimensional stability and fuel barrier characteristics, and shows excellent proton conductivity at high temperature, a method for producing the same, and fuel cell using the same CONSTITUTION: The proton-conducting membrane comprises a carbon-containing compound and inorganic acid and is characterized by a phase-separated structure containing a carbon-containing phase containing at least 80% by volume of the carbon-containing compound and inorganic phase containing at least 80% by volume of the inorganic acid, wherein the inorganic phase forms the continuous ion-conducting paths.
