Title:
POLYMER ELECTROLYTE MEMBRANE, MEMBRANE ELECTRODE ASSEMBLY USING SAME, AND SOLID POLYMER FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2013/031675
Kind Code:
A1
Abstract:
Provided is a polymer electrolyte membrane that has excellent proton conductivity even under low humidification conditions, has excellent mechanical strength and chemical stability, and can achieve high output and excellent physical durability when made into a solid polymer fuel cell. This polymer electrolyte membrane comprises a block copolymer including at least one each of a segment (A1) that contains an ionic group and a segment (A2) that does not contain an ionic group, the polymer electrolyte membrane being characterized by: forming a co-continuous (M1) or lamellar (M2) phase-separated structure; and having a crystallization heat quantity of 0.1 J/g or greater as measured by differential scanning calorimetry, or a degree of crystallinity of 0.5% or greater as measured by wide-angle X-ray diffraction.
