Title:

COMPOSITE POLYMER ELECTROLYTIC MEMBRANE, AND MEMBRANE ELECTRODE COMPOSITE AND SOLID POLYMER FUEL CELL USING SAME

Document Type and Number:

WIPO Patent Application WO/2017/141878

Kind Code:

A1

Abstract:

Provided are: a composite polymer electrolytic membrane that has excellent proton conductivity even under low-humidification and low-temperature conditions, a small dimensional change rate, and excellent mechanical strength and chemical stability, and that is capable of achieving a high output and excellent physical durability when being used in a solid polymer fuel cell; and a membrane electrode composite and a solid polymer fuel cell using the composite polymer electrolytic membrane. This composite polymer electrolytic membrane has a composite layer formed by combining a polyazole-containing nanofiber unwoven fabric (A) and an ionic-group-containing polymer electrolyte (B), and is characterized in that the polyazole-containing nanofiber unwoven fabric (A) is basic.
