Title:
ELECTROLYTE FILM AND SOLID POLYMER FUEL CELL USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2003/081706
Kind Code:
A1
Abstract:
An electrolyte film having a porous base material having pores filled with a first polymer capable of conducting a proton, wherein the porous base material comprises at least one second polymer selected from the group consisting of polyimides and polyamides; and a fuel cell, particularly a solid polymer fuel cell, more specifically a direct methanol polymer fuel cell, using the electrolyte film. The electrolyte film is excellent in the inhibition of permeation of methanol, exhibits no or reduced change in its area, and is excellent in proton conductivity.
