    Abstract: A flow battery includes at least one electrochemical cell that has a first electrode, a second electrode spaced apart from the first electrode and a separator arranged between the first electrode and the second electrode. A first storage portion and a second storage portion are respectively fluidly connected with the at least one electrochemical cell. A first liquid electrolyte and a second liquid electrolyte are located in the respective first storage portion and second storage portion. The first electrode has an area over which it is catalytically active with regard to the first liquid electrolyte and the second electrode has an area over which it is catalytically active with regard to the second liquid electrolyte such that the area of the first electrode is greater than the area of the second electrode.

    Abstract: A method of determining a distribution of electrolytes in a flow battery includes providing a flow battery with a fixed amount of fluid electrolyte having a common electrochemically active specie, a portion of the fluid electrolyte serving as an anolyte and a remainder of the fluid electrolyte serving as a catholyte. An average oxidation state of the common electrochemically active specie is determined in the anolyte and the catholyte and, responsive to the determined average oxidation state, a molar ratio of the common electrochemically active specie between the anolyte and the catholyte is adjusted to increase an energy discharge capacity of the flow battery for the determined average oxidation state.

    Abstract: A method is disclosed for regenerating an electrode of a flow battery. The method can be executed during shutdown of the flow battery from an active charge/discharge mode to an inactive, shut-down mode in which neither a negative electrolyte nor a positive electrolyte are circulated through at least one cell of the flow battery. The method includes driving voltage of the least one cell of the flow battery toward zero by converting, in-situ, the negative electrolyte in the at least one cell to a higher oxidation state. The negative electrolyte is in contact with an electrode of the at least one cell. The higher oxidation state negative electrolyte is used to regenerate, in-situ, catalytically active surfaces of the electrode of the at least one cell.

    Abstract: A flow battery includes a liquid electrolyte that has an electrochemically active specie and a bipolar plate that has channels for receiving flow of the liquid electrolyte. A porous electrode is arranged immediately adjacent the bipolar plate. The porous electrode is catalytically active with regard to the liquid electrolyte. The channels of the bipolar plate have at least one of a channel arrangement or a channel shape that is configured to positively force at least a portion of the flow of the liquid electrolyte into the porous electrode.
