ABSTRACT:
Shunt currents can be eliminated in electrochemical devices by introducing nulling currents via auxilary electrodes. In electrochemical devices including those having a circulating electrolyte, such electrodes are designed to have a generally annular shape in order to provide a substantially uniform current density profile along a common electrolyte carrying manifold. The uniform current density profile allows for the elimination of these harmful shunt currents with a minimum of power consumption.
