ELECTROLYTE MEMBRANE FOR ELECTROCHEMICAL CELL, ITS MANUFACTURING METHOD, ELECTROCHEMICAL CELL, AND OPERATION METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To keep an ion conductivity high, and to enhance operation efficiency, while maintaining a moisture content in an inside of a solid electrolyte membrane in an electrochemical cell.

SOLUTION: This electrochemical cell operation method is provided with steps for: measuring a concentration of an acidic solution; regulating a concentration of the acidic solution to a reference concentration based on a measured result in the concentration measurement hereinbefore and the preset reference concentration; supplying the acidic solution adjusted to the reference concentration into the inside of the solid electrolyte membrane in the electrochemical cell; and making the acidic solution passed through the inside of the solid electrolyte membrane flow out from the electrochemical cell.
