Abstract:
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. [Reference numerals] (AA) Polymer film containing surface treated inorganic particles; (BB) Polymeric acid monomer dopping; (CC) Polymerization
Abstract:
Disclosed are an electrolyte membrane that can be operated under the conditions of high temperature and low humidity; a manufacturing method thereof; and a membrane electrode assembly and a fuel cell including the same. The electrolyte membrane comprises: a host polymer having a molecular structure of the molecular chain of a fluorine-based polymer with a structure of (-CF2-CF(M)CH2-CF2-), wherein M is CF3, CF2H or CFH2, chemically crosslinked by a low-molecular-weight basic compound with at least two amino groups; and a proton-conductive polymer having an acid group and one or more kinds of polymerizable functional groups, and having a molecular structure of a polymeric molecular chain, which is obtained by polymerizing low-molecular-weight polymerizable hydrogen ion conductor including the property of proton dissociation, chemically crosslinked by a crosslinking agent, wherein the molecular chain of the host polymer is interlaced with the molecular chain of the proton-conductive polymer to form an interpenetrating polymer network (IPN).
