View the Complete Application at the US Patent & Trademark Office
Methods and apparatuses are disclosed for mitigating electrolyte migration in a redox flow battery system. A first parameter of a first electrolyte in a first flow path of a redox flow battery cell block may be measured. The first flow path may have an inlet to and an outlet from the redox flow battery cell block. A second parameter of a second electrolyte in a second flow path of the redox flow battery cell block may be measured. The second flow path may have an inlet to and an outlet from the redox flow battery cell block. The first parameter may be detected to be greater than the second parameter. A first device coupled to the redox flow battery cell block in the second flow path may be operated to increase the second parameter in the second flow path.
