    摘要: The present invention relates to a sulfonated polyethersulfone copolymer containing hydroxyl groups, a preparing method thereof, a polymer electrolyte membrane for a fuel cell and a membrane electrode comprising the same and more particularly, to a polymer electrolyte membrane having much higher ionic conductivity than existing sulfonated polymer electrolyte membranes by applying a sulfonated polyethersulfone electrolyte membrane containing hydroxyl groups and a membrane electrode assembly comprising the same to a fuel cell. The sulfonated polyethersulfone copolymer electrolyte membrane containing hydroxyl groups manufactured according to the present invention is expected to substitute for fluorinated polymer electrolyte membranes such as high-priced Nafion because the sulfonated polyethersulfone copolymer electrolyte membrane has much higher ionic conductivity under the conditions of various temperatures and pressures than existing sulfonated polymer electrolyte membranes. Moreover, the polymer electrolyte membrane for a fuel cell manufactured according to the present invention can be applied to a membrane electrode assembly for a fuel cell by being arranged between an anode and a cathode and the membrane electrode assembly can be applied to the key components of an electrolyte membrane fuel cell.

    摘要: PURPOSE: An electrolyte film for fuel cells is provided to have excellent strength while suppressing acid component eruption. CONSTITUTION: An electrolyte film(13) for fuel cells is obtained by impregnating a polymerizable acid monomer(12) into a polymer film(10) which contains inorganic particles(11) surface-treated by a polymerizable double bond-containing surface treating agent; and polymerizing the polymerizable acid monomers. The amount of the polymer film is 1-50 weight% based on the 100.0 parts by weight of the polymer film. A membrane-electrode assembly for fuel cells comprises a fuel electrode; an oxygen electrode; and an electrolyte film for fuel cells, between the oxygen electrode and the fuel electrode.
