    摘要: 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.

    摘要: The invention features an electrochemical cell having two fluid-containing compartments separated by a nonselective microporous membrane. Select ions which would normally pass through the membrane under the influence of an ionic field, are prevented from passing through the membrane by a polyelectrolyte which has migrated through the compartment fluid to the membrane. The polyelectrolyte acts as an ionic barrier to the passage of select ions, thus effectively increasing the ion-selective capability of the membrane and, hence, the coulombic efficiency of the electrochemical cell.

    摘要: 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.
