Patent abstract
A redox flow battery system including a reactive cell with an anode chamber separated from a cathode chamber separated by an ion-permeable membrane is provided. A catholyte reservoir is connected to the cathode chamber by a catholyte fluid circulation circuit. An anolyte reservoir is connected to the anolyte chamber by an anolyte fluid circulation circuit. Nitrogen sparging of reactive oxygen from the catholyte fluid in the catholyte reservoir prevents the formation of a finely divided solid precipitate in the catholyte fluid. Nitrogen may be provided from an external source of nitrogen. Nitrogen may also be provided by the in situ generation of nitrogen from air.
