METHOD OF PRODUCING POLYELECTROLYTE-CONTAINING SOLUTION AND SOLID POLYELECTROLYTE FILM

摘要

PROBLEM TO BE SOLVED: To provide a polyelectrolyte-containing solution with which a solid polyelectrolyte film having high durability can be obtained, and provide a solid polyelectrolyte film formed by using the solution.SOLUTION: A method of producing a polyelectrolyte-containing solution at least includes a first step in which a perfluorocarbon sulfonic acid resin (component A), an amine compound (component B), a polyazole compound (component C) and an alkali metal hydroxide (component D) are dissolved or suspended in a protic solvent.
