HYDROCARBON MEMBRANES COMPRISING SILANE COMPOUND, METHOD FOR MANUFACTURING THE SAME, MEA AND FUEL CELL USING THE SAME

摘要

PURPOSE: A hydrocarbon proton-conductive polymer membrane is provided to obtain excellent electrochemical, mechanical, and thermal properties and to have superior proton conductivity at a high temperature and a high pressure. CONSTITUTION: A hydrocarbon proton-conductive polymer membrane includes a hydrocarbon polymer having a cation exchanger and a silane compound having an amino group which is substituted to phosphoric acid. A method for manufacturing the hydrocarbon proton-conductive polymer membrane comprises the following steps: dissolving the hydrocarbon polymer having a cation exchanger and a silane compound in an organic solvent; forming a polymer membrane by drying a polymer solution after mixing the polymer solution in which the silane compound is dispersed; combining the silane compound and the cation exchanger by heating the polymer membrane; and giving ion conductivity by heating the polymer membrane in phosphoric acid solution.
