Title:
POLYMER ELECTROLYTE MATERIAL, POLYMER ELECTROLYTE MOLDED PRODUCT USING THE POLYMER ELECTROLYTE MATERIAL AND METHOD FOR MANUFACTURING THE POLYMER ELECTROLYTE MOLDED PRODUCT, MEMBRANE ELECTRODE COMPOSITE, AND SOLID POLYMER FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2008/018487
Kind Code:
A1
Abstract:
This invention provides a polymer electrolyte material, which has excellent
proton conductivity even under low humidity and low temperature conditions
and excellent mechanical strength and fuel shielding properties and, in the
form of a solid polymer fuel cell, can realize high output, high energy density,
and long-term durability, and a polymer electrolyte molded product using the
polymer electrolyte material, a method for producing the polymer electrolyte
molded product, a membrane electrode composite, and a solid polymer fuel cell.
The polymer electrolyte material comprises ionic group-containing constitutional
units (A1) and substantially ionic group-free constitutional units (A2) and
is characterized in that a phase separated structure can be confirmed by observation
under a transmission electron microscope and, at the same time, the crystallization
heat quantity as measured by a differential scanning calorimetric analysis
is not less than 0.1 J/g, or characterized in that a phase separated structure
can be confirmed by observation under a transmission electron microscope and,
at the same time, the degree of crystallization as measured by a wide angle X-ray
diffraction analysis is not less than 0.5%.
