Abstract
Abstract A multicell seawater battery is described wherein a series of cells each having a metal halide cathode, a metal anode and an electrolyte space between, is arranged in face to face orientation. A first duct is provided at the bottom of the battery with ports leading to the bottom of each cell. A second duct is provided at the top of the battery with ports leading to the top of each cell. A reservoir is provided behind each metal anode, at the top of each reservoir a port connects to the second duct of the battery located at the top of the battery. A third duct is provided at the bottom of the battery with ports leading to the bottom of each reservoir. One or more ports are provided in each cell leading from the reservoir through the metal anode to the electrolyte space. By this configuration, a first electrolyte circulation path is sustained from the third duct (at the bottom of the battery) into the reservoir, through the port or ports in the anode and out the second duct (at the top of the battery) while at the same time a second circulation path exists from the electrolyte space through the first duct (at the bottom of the battery). In addition, the reservoir is available to feed fresh electrolyte to the cell via the port or ports therebetween.
