Abstract: Systems and methods are provided for a rebalancing cell for a redox flow battery. In one example, a rebalancing cell for a redox flow battery includes a cell enclosure and a stack of electrode assemblies enclosed by the cell enclosure, where each electrode assembly of the stack of electrode assemblies including a positive electrode interfacing with a flow field plate. A face of the flow field plate interfacing with the positive electrode has a plurality of passages including tapered inlets and outlets and partial channels configured to remove gas from electrolyte flowing therethrough.
