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 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.
