摘要: The present disclosure relates to an electrochemical cell comprising a fuel electrode for oxidizing a fuel, an oxidant electrode for reducing an oxidant, and an ionically conductive medium for conducting ions between the fuel and oxidant electrodes to support electrochemical reactions at the fuel and oxidant electrodes. The ionically conductive medium comprises at least one active additive for enhancing (controlling the rate, overpotential and/or the reaction sites for) at least one electrochemical reaction within the cell. The cell further comprises an additive medium in contact with the ionically conductive medium and containing the at least one active additive capable of corroding or dissolving in the ionically conductive medium. The additive medium and/or casing is configured to release the active additive to the ionically conductive medium as a concentration of the active additive in the ionically conductive medium is depleted during operation of the cell.

摘要: An electrochemical cell system and a process for operating the same, the system having at least two fuel electrodes for receiving electrodeposited metal fuel; at least one oxidant electrode spaced apart from the fuel electrode; at least one charging electrode; an ionically conductive medium communicating the electrodes of the electrochemical cell system for conducting ions to support electrochemical reactions at the fuel, oxidant, and charging electrodes; and, one or more controllers configured to operate the cell system in discharging and charging modes and monitor a state of charge for each fuel electrode. The controllers may assign each fuel electrode in a discharging unit having a state-of-charge meeting a predetermined depletion criteria from the discharging unit to the charging unit, and each fuel electrode in the charging unit having a state-of-charge meeting a predetermined loading criteria from the charging unit to the discharging unit.
