Shunt currents in electrochemical systems with liquid electrolytes are reduced by placing shunt resistors in electrolyte flow paths. Shunt resistors substantially increase electrical resistance in electrolyte flow channels by interrupting the physical continuity of liquid through their length. Some shunt resistors also provide a flow metering, pumping or flow-resisting functions for improved electrolyte flow control.
