  • High performance redox flow battery stack
    Patent number: 10381667
    Abstract: A redox flow battery stack cell frame comprising a support frame and a monolithic bipolar plate integrated within the support frame is disclosed. The bipolar plate comprises a plurality of interdigitated flow channels on at least one surface. The support frame comprises an inlet manifold formed into a facing surface of the first side of the frame, the inlet manifold comprising fluid inlet distribution channels in a serpentine arrangement, each fluid inlet distribution channel aligned with a single inlet flow channel of the bipolar plate; and an outlet manifold formed into the facing surface of the opposing side of the frame, the outlet manifold comprising fluid outlet distribution channels in a serpentine arrangement, each fluid outlet distribution channel aligned with a single outlet flow channel of the bipolar plate. Redox flow battery stack cells and stacks comprising the stack cell frame are also disclosed.
