PURPOSE:To obtain an ion conductive membrane whose electrochemical property can be varied in a wide scope without removing from a basic member by preparing perfluorosulfonate polymer solution to make specific cations into antiion in an ion exchange, and casting the polymer solution. CONSTITUTION:By ion-exchanging perfluorosulfonate polymer solution, perfluorosulfonate polymer solution or perfluorosulforic acid polymer solution which makes specific cations into antiion is prepared, and the polymer solution is casted. As a result, a soaking process to an acid or the like after the casting is unnecessary. Consequently, no fear of removing the casting film from a basic member, an ion conductive membrane of a good adhesive property can be obtained, and, at the same time, the ion-exchange to specific cations can be carried out more efficiently, and the ion conductibility of the produced membrane is improved. |
