POLYMER ELECTROLYTE OF SOLID POLYMER FUEL CELL, METHOD FOR MANUFACTURING THE SAME, MEMBRANE-ELECTRODE ASSEMBLY CONTAINING POLYMER ELECTROLYTE, AND METHOD FOR MANUFACTURING THE SAME MEMBRANE-ELECTRODE ASSEMBLY

摘要

PPROBLEM TO BE SOLVED: To provide a method for manufacturing a polymer electrolyte which has high proton conductivity and high gas permeability without changing a structure of the polymer electrolyte, and a solid polymer fuel cell having a membrane-electrode assembly including the polymer electrolyte. PSOLUTION: In the manufacturing method for a polymer electrolyte, a polymer electrolyte ink including a polymer electrolyte dispersion solution, a solvent, and an organic object wherein dipole moment is 2.0 D or more is produced, a coated film is formed by applying the polymer electrolyte ink to a base material, and the organic object in the film attained by drying the coated film is removed with acid treatment. Thus, the polymer electrolyte having high proton conductivity and high gas permeability can be attained. PCOPYRIGHT: (C)2011,JPO&INPIT
