Shunt current in a redox flow cell stack has been numerically analyzed by a simple equivalent circuit model. Calculated efficiencies are in agreement with the test results. Thus, the method is useful for estimation of the shunt current loss of cell stacks. Pumping loss has also been numerically analyzed. Effects of parameters, such as the electrode area of flow cell, the charge and discharge current, and the number of cells connected in series, upon the shunt current and the pumping loss are discussed. Computer simulation on the shunt current and the pumping loss is shown to be effective in designing and optimizing the redox flow cell system.
