Abstract: One aspect of the present invention provides a rechargeable electrochemical cell system for generating electrical current using a fuel and an oxidant. The cell system comprises N electrochemical cells each comprising a fuel electrode, an oxidant electrode, a charging electrode, and an ionically conductive medium communicating the electrodes, wherein N is an integer greater than or equal to two. Any number of cells may be used. The cell system includes a plurality of switches that are switcheable to a discharge mode coupling the oxidant electrode of each cell to the fuel electrode of the subsequent cell, a charge mode coupling the charging electrode of each cell to the fuel electrode of the subsequent cell, and a bypass mode coupling charging electrode or the oxidant electrode of a previous cell to the fuel electrode of a subsequent cell.

Abstract: Active metal fuel cells are provided. An active metal fuel cell has a renewable active metal (e.g., lithium) anode and a cathode structure that includes an electronically conductive component (e.g., a porous metal or alloy), an ionically conductive component (e.g., an electrolyte), and a fluid oxidant (e.g., air, water or a peroxide or other aqueous solution). The pairing of an active metal anode with a cathode oxidant in a fuel cell is enabled by an ionically conductive protective membrane on the surface of the anode facing the cathode.
