Abstract

PURPOSE:To decrease power consumption of auxiliary powers for maintaining a certain rated output time in a charging/discharging device having a cell stack of solution circulation type, by making a porous electrode with a specific thickness. CONSTITUTION:Electrolyte in tanks 2, 3 are poured by a small pump 8 from the bottoms of a positive and a negative electrode chamber. The electrolyte passes porous electrodes 4, 5, performs electrode reaction, and is bled out from the top to be returned to the tanks 2, 3. When the electrodes 4, 5 are given a thickness over 8mm, the rated output time by the pump 8 will exceed 30 min, and the apparent linear speed perpendicular to a diaphragm 6 and a complex electrode partition plate 7 become below 0.5cm/sec. When the electrodes 4, 5 are, on the other hand, given a thickness no more than 8mm, the rated output time becomes below 30 min. Thus the power consumption of an aux. power unit to supply the electrolyte will be decreased to lead to enhancement of the charging/discharging efficiency.
