The performance of a monopolar aqueous battery system (10) may be enhanced by circulating the electrolyte. However, the circulating electrolyte produces undesirable shunt currents when the system is electrically connected in a series array. Such a battery system (10) includes cells (11a-11d) electrically connected in series and hydraulically connected in parallel, and means defining a hydraulic pathway (12a, 12b) for an electrolyte common to at least two of the cells. An electrical electrolytic conductive bypass path is formed through the shared electrolyte around the cells (11a-11d). To reduce or eliminate the shunt currents in the shared electrolyte means (21a, 21b, 22a, 22b) are included for applying a protective current which results in a REDOX reaction couple, wherein water is electrically consumed at the protective current anode (21a, 22a) and electrically replaced at the protective current cathode (22a, 22b). The protective current is applied through at least a part of the conductive bypass path through the shared electrolyte in the same direction as the shunt current, of a magnitude to at least reduce the shunt current. |
