Abstract
A polymer electrolyte-containing solution is obtained by preparing a first solution, preparing a second solution and mixing the first and second solutions. The first solution is prepared by dissolving a perfluorocarbonsulfonic acid resin (component A) having an ion-exchange capacity of 0.5 to 3.0 meq/g in a protic solvent. The second solution is prepared separate from the first solution, by dissolving a polyazole-based compound (component B) and an alkali metal hydroxide in a protic solvent. The first and second solutions are mixed to prepare a polymer electrolyte-containing solution in which a weight ratio of the component A to component B, (A/B) , is from 2:3 to 199 and a total weight of the component A and the component B is from 0.5 to 30% by weight on the basis of the solution including the protic solvent. The protic solvent is an aliphatic alcohol.
