Japanese Patent JP5822639

B2

PROBLEM TO BE SOLVED: To produce an ion conductivity imparting agent solution in which an ion conductivity imparting agent is dissolved into a single solvent having a desirable drying rate, without causing any decrease in ion-exchange capacity.SOLUTION: The production method of an ion conductivity imparting agent solution containing an ion conductive block copolymer and being used for preparation of the catalyst electrode layer of a fuel cell includes a step for preparing a mixed solution containing an ion conductivity block copolymer including a block having an ionic group, and more than one kind of solvent having different boiling point in which the block copolymer is dissolved into the solvent, and a step for subsequently removing a solvent having a lower boiling point from the mixed solution.
