摘要： A flow battery comprises a plurality of unit cells each constituted of stacked unit cells each consisting of a prescribed number of stacked diaphragms and positive electrode chambers and negative electrode chambers separated by the diaphragms, a positive electrode fluid tank associated with each unit cell to have its outlet connected with an inlet of the positive electrode chamber of the unit cell and its inlet connected with an outlet of the positive chamber of a immediately preceding unit cell, a negative electrode fluid tank associated with each unit cell to have it outlet connected with an inlet of the negative chamber of the unit cell and its inlet connected with outlet of the negative chamber of an immediately preceding unit cell, a pump for supplying positive electrode fluid from the positive electrode fluid tanks to the positive electrode chambers, a pump for supplying negative electrode fluid from the negative electrode fluid tanks to the negative electrode chambers, and means for electrically connecting the plurality of unit cells in series. The flow battery of this configuration achieves improved charge/discharge coulomb efficiency and voltage efficiency, without reducing pump efficiency, and, by increasing the length, and thus the resistance, of the leakage current path reduces the amount of leakage current.
