Abstract
Provided is a rechargeable electrochemical cell system for generating electrical current using a fuel and an oxidant. The system includes a plurality of electrochemical cells. A controller is configured to apply an electrical current between charging electrode(s) and a fuel electrode with the charging electrode(s) functioning as an anode and the fuel electrode functioning as a cathode, such that reducible metal fuel ions in the ionically conductive medium are reduced and electrodeposited as metal fuel in oxidizable form on the fuel electrode. The controller may selectively apply current to a charging electrode and third electrode between fuel electrodes of separate cells to increase uniformity of the metal fuel being electrodeposited on the fuel electrode. The controller controls a number of switches to apply current to the electrodes and select different modes for the system. Also provided are methods for charging and discharging an electrochemical cell system, and selecting different modes.
