PROTON CONDUCTIVE MEMBRANE, ITS MANUFACTURING METHOD, AND SOLID POLYMER TYPE FUEL CELL USING PROTON CONDUCTIVE MEMBRANE
Document Type and Number:
Japanese Patent JP2005285413
Kind Code:
A
Abstract:
To provide a proton conductive membrane having sufficiently high proton conductivity, sufficiently low methanol permeability and physical strength withstanding the reduction of thickness.
In this proton conductive membrane having an inorganic porous membrane containing proton conductive organic material, the inorganic porous membrane is formed of a group of at least two kinds of inorganic fine particles having different average particle diameters.
