ELECTROLYTE MEMBRANE FOR POLYMER FUEL CELL, ELECTROLYTE-MEMBRANE/CATALYST-LAYER JUNCTION MATERIAL AND ELECTROLYTE-MEMBRANE/ELECTRODE JUNCTION MATERIAL USING THE SAME, AND FUEL CELLS

摘要

PPROBLEM TO BE SOLVED: To provide an electrolyte membrane for polymer fuel cell having an even distribution and rigid structure with high stability in size and high performance for gas barrier; and to provide an electrolyte-membrane/catalyst-layer junction material and electrolyte-membrane/electrode junction material using the same, and fuel cell. PSOLUTION: The electrolyte membrane for polymer fuel cell contains a proton conductive materials A(2) and B(3). The proton conductive material A(2) has a film-forming capability obtained by self-assembly function. The electrolyte-membrane/catalyst-layer junction material has a catalyst layer comprising a catalyst particle and an electrolyte binder on both front and back sides of the electrolyte membrane, and layered in such structure as catalyst layer/electrolyte membrane/catalyst layer. The electrolyte-membrane/electrode junction material has the catalyst layer comprising the catalyst particle and the electrolyte binder, and electrode comprising an electrode base material, as layered in such structure from the front surface as electrode base material/catalyst layer/electrolyte membrane/catalyst layer/electrode base material. The electrolyte-membrane/electrode junction material is used for the fuel cell. PCOPYRIGHT: (C)2009,JPO&INPIT
