Title:
ELECTROLYTIC FILM, FILM-ELECTRODE ASSEMBLY, AND SOLID POLYMER TYPE FUEL BATTERY
Document Type and Number:
Japanese Patent JP2015008060
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electrolytic film well-balanced and superior in its power generation performance, water repellency, the adhesion with an electrode, and dimensional stability in a dry-wet cycle.SOLUTION: An electrolytic film comprises: a polymer (1) having a hydrophilic segment (A1) and a hydrophobic segment (B1); and a polymer (2) which is different from the polymer (1) and having no sulfonic group. The polymer (2) includes a hydrophobic segment (B1') compatible to the segment (B1), and 0-50 wt.% of a hydrophobic segment (B2) different from the segment (B1') to the total of the polymer (2). The electrolytic film has a contact angle of 45-120° to water.
