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.
Claims17
A protective annular electrode for providing a substantially uniform current density along a common manifold of an electrochemical device for reducing or otherwise eliminating undesirable shunt currents in said electrochemical device, comprising:
- an annular sleeve;
- means for passing current through said sleeve;
- a first means for passing a fluid material through said sleeve;
- a second means for passing a fluid material through said sleeve;
- and
- an inner liner disposed within said sleeve for selectively passing a material to the exclusion of other materials.
