PURPOSE: Provided are a proton conductive membrane, a preparation method thereof, and a fuel cell containing the proton conductive membrane. The proton conductive membrane has excellent proton conductivity under the condition of high temperature and low humidity. CONSTITUTION: The proton conductive membrane is a polymer membrane containing molten salts, which is produced by a process comprising the steps of: dissolving a polymer which has at least one aromatic ring on the backbone thereof and contains a sulfone group or a phosphone group in a solvent to prepare a solution; injecting the molten salts comprising cations containing nitrogen or phosphorus and anions of fluorine-containing salts into the obtained solution; removing the solvent by heating the solution. The fuel cell contains a fuel electrode, an oxidant electrode, a polymer membrane, a fuel supply plate, and an oxidant supply plate, wherein at least one of the fuel electrode, the oxidant electrode, and the polymer membrane contains the polymer having at least one aromatic ring on the backbone thereof and the sulfone group or the phosphone group and the molten salts comprising the cations containing nitrogen or phosphorus and the anions of fluorine-containing salts. |
