<p>An electrolyte film having a porous base material which is not swelled substantially with an organic solvent containing methanol or water and has pores filled with a first polymer capable of conducting a proton, characterized in that the first polymer is derived from 2-acrylamide-2-methylpropanesulfonic acid; 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.</p> |
