Title:
MEMBRANE ELECTRODE JUNCTION, AND MANUFACTURING METHOD OF MEMBRANE ELECTRODE JUNCTION INTERMEDIATE BODY USING THE SAME
Document Type and Number:
Japanese Patent JP2005011590
Kind Code:
A
Abstract:
To provide a membrane electrode junction capable of restraining interlayer separation due to water-absorptive expansion among a proton exchange membrane 3, a catalyst layer 4 and a diffusion layer 5.
The catalyst layer 4 is directly formed on an electrode base material (for instance, a diffusion layer 5) by applying catalyst ink prepared by dispersing a catalyst supporting conductor in a solvent. In addition, the proton exchange film 3 is directly formed on the formed catalyst layer by applying a solution prepared by dissolving a proton exchange material in a solvent.
