Title:
ELECTROLYTE MATERIAL, LIQUID COMPOSITION, AND MEMBRANE ELECTRODE ASSEMBLY FOR POLYMER ELECTROLYTE FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2013/157395
Kind Code:
A1
Abstract:
Provided are a membrane electrode assembly that has excellent power generation properties and is less susceptible to breaking of a catalyst layer even under low-humidity to no-humidity conditions as well as under high-humidity conditions, and an electrolyte material suitable for the catalyst layer of the membrane electrode assembly. Used is an electrolyte material comprising a polymer (H) including: a unit (A) which has an ion exchange group and in which all hydrogen atoms bonded to carbon atoms are substituted by fluorine atoms; a unit (B) which has a five-membered ring and in which all hydrogen atoms bonded to carbon atoms are substituted by fluorine atoms; and a unit (C) which has neither an ion exchange group nor a ring structure, has an ether bond, and has an ether equivalent of 350 or less as established by formula (I), and in which all hydrogen atoms bonded to carbon atoms are substituted by fluorine atoms. Formula (I): Ether equivalent = the molecular weight of the monomer forming the unit (C)/the number of ether bonds in the monomer forming the unit (C).
