A multi-cell metal/air battery is described having series-connected cells, including a tank for holding a body of liquid electrolyte, and an electrically non-conductive frame carrying a plurality of air cathode assemblies, each cathode assembly having a common air pocket and a pair of cathodes, and a like plurality of anodes respectively juxtaposed to the cathodes outside the air chamber, the air cathode assemblies being removably insertable in the tank and engaging the tank wall, when inserted, so as to divide the tank into a plurality of separate and substantially electrically isolated electrolyte-holding zones each containing one anode-cathode pair. The air cathode assembly may include an air circulation system to keep the air in the pocket fresh. The tank may also include an electrolyte distribution system and a flushing system for flushing the battery without the need to remove the cathodes and anodes from the tank.

A metal air battery comprising (a) a tank defining a single continuous reservoir for liquid electrolyte; (b) a plurality of air cathode assemblies removably supported from a top support framework for insertion into the reservoir, each assembly comprising a pair of air cathodes supported in an electrically non-conductive frame in electrically isolated relation to each other and defining between first surfaces thereof a liquid-tight air chamber open to ambient atmosphere, and said assemblies being removably insertable in the reservoir to expose second cathode surfaces remote from the air chamber to electrolyte therein; (c) a plurality of metal anodes, one for each cathode assembly, removably carried by said cathode assemblies and disposed for immersion in electrolyte in the reservoir in spaced juxtaposed relation to the cathode second surfaces to constitute therewith a plurality of anode-cathode pairs each electrically coupled by electrolyte; (d) circuit means for connecting said anode-cathode pairs in series to each other and to an external load; and (e) engaging means includes electrically non-conductive fins projecting from each side of said frame and an electrically non-conductive fin projecting from the bottom of said frame for engaging said tank when the assembly is inserted in the reservoir, to divide the reservoir into a plurality of separate and substantially electrically isolated electrolyte-holding zones each containing one anode and the cathode second surface juxtaposed thereto, so as to inhibit anode-to-anode current flow through the electrolyte, and each electrolyte-holding zone including a refuse collecting zone located below the bottoms of the anode and cathode.
