Abstract:
1. A flow battery system, comprising: a stack of flow battery cells, wherein each cell in the stack of cells comprises: an electrolyte storage reservoir; a flow circuit configured to deliver the metal halide electrolyte to the stack of cells wherein the flow circuit comprises a feed manifold configured to deliver the electrolyte from the reservoir to the stack of cells and a return manifold configured to deliver the electrolyte from the stack of cells to the reservoir, a circulation pump which is configured to convey the electrolyte from the reservoir to the stack of cells through the flow circuit; and a plurality of conductive spacers which electrically connect the first porous electrode of each cell to the second non-porous electrode of an adjacent cell in the stack of cells; wherein an inlet for the electrolyte for each cell in the stack of cells is located between the conductive spacers on a first side of the first porous electrode and an outlet for the electrolyte for each cell in the stack is located in the reaction zone on a second side of the first porous electrode.
