PURPOSE:To increase energy density by dividing a storage tank into plural chambers, installing a switching means for the inflow and outflow of discharge solution/charge solution, and using the chamber as a switching charge solution storage chamber. CONSTITUTION:A discharge solution/charge solution storage tank 7 is divided into plural chambers. To separately storage a discharge solution 5 and a charge solution 6, a valve A9 and a valve B10 for the inflow and the outflow of discharge solution 5/charge solution 6 are installed under discharge solution 5/charge solution 6 chambers respectively. The valve A9 under the discharge solution 5 chamber and the valve B10 under the charge solution 6 chamber are opened, and the charge solution 6 is fed to an electrolyte flow type cell 1 with a pump 8 for discharge, and the solution after discharge is sent back to the discharge solution storage chamber in the tank 7 through the valve A9 and stored there. When the cell 1 is charged, opposite procedure is conducted. The volume space of the storage tank is reduced and energy density is increased. |
