ABSTRACT:
Electrochemical systems having a plurality of cells which are hydraulically and electrically connected in series develop shunt currents in the electrolyte of adjacent cells. The shunt currents are reduced or eliminated by the placing of an electrical bypass across two adjacent intercell conduits, and applying a protective current through the electrical bypass in a direction of the shunt currents and of a magnitude that can effectively reduce the shunt currents.
