Title:
ELECTROLYTE MEMBRANE FOR SOLID POLYMER FUEL CELL AND MEMBRANE ELECTRODE ASSEMBLY FOR SOLID POLYMER FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2010/098398
Kind Code:
A1
Abstract:
Disclosed are an electrolyte membrane for solid polymer fuel cells that has excellent dimensional stability when hydrated and which suppresses increased resistance caused by a reinforcing material; and a membrane electrode assembly for solid polymer fuel cells that has excellent durability and high output.
An electrolyte membrane (100) is reinforced with a reinforcing material. The reinforcing material is a nonwoven cloth that includes fibers of a fluorine resin with a storage elastic modulus (E') at 90°C of not less than 1.9 × 108 Pa, and a storage elastic modulus (E') at 210°C of not more than 4 × 107 Pa, and the thickness of said nonwoven cloth is 0.5‑15 µm. A membrane electrode assembly (70) is equipped with a cathode (90), an anode (80), and the electrolyte membrane (100), which is disposed between the cathode (90) and anode (80).
