Abstract

PURPOSE:To suppress the characteristic deterioration of a cell by detecting the internal resistance of the cell during the operation by the AC four-terminal method and adding steam into the reaction air when the internal resistance is increased to supply moisture to the holding matrix or a phosphoric acid electrolyte. CONSTITUTION:An internal resistance measuring instrument 4 by the AC four- terminal method is provided between terminals of a cell, and the internal resistance is measured during the cell operation. When the resistance value becomes 1.2-1.5 times of the initial value, the signal 4' of the detector 4 is sent to an actuator 7, a steam feed valve 8 is opened, and steam 9 is fed to a humidifier 6. The reaction air quantity is changed in response to the fluctuation of a cell load, this change is detected by a flow detector 5, a valve 8 is adjusted by an actuator 7 so that the steam addition ratio is not changed. Steam 9 is absorbed into the phosphoric acid electrolyte in a matrix M, and moisture is supplied to the electrolyte. As a result, the internal resistance is reduced, and the characteristic deterioration of the cell is suppressed.
