ABSTRACT:
Shunt currents can be eliminated in electrochemical devices by introducing nulling currents via auxiliary electrodes. The invention teaches the reduction or elimination of these shunt currents in such devices with minimized power consumption. Shunt current nulling tunnels are provided which interconnect with electrolyte supply channels feeding the cells of the electrochemical device. Power consumption for the shunt current-nulling tunnels is reduced by designing the tunnels to have an increasing electrical resistance towards their mid-portions. Another embodiment of the invention features an increasing electrical resistance towards the mid-portion of the tunnels and a decreasing electrical resistance towards the mid-portion of the manifolds.
