Shunt Current Control Methods In Electrochemical Systems — Applications

Abstract

Shunt current effects in common electrolyte series-connected cell systems can be eliminated by passing an appropriate current through the common electrolyte manifolds or channel interconnects. Electrical shunt current control theories have been verified and the techniques have been applied to batteries and electrolysis systems. The technique appears to be generally applicable to electrochemical systems.
