ABSTRACT:
The invention provides an electrochemical zinc-air multi-cell battery, each cell being of the type provided with a housing having a base, two major surfaces and two minor surfaces, defining an interior space for containing therein a zinc electrode; at least one generally planar air permeable but liquid impermeable air electrode, each of the at least one air electrode being installed in a window opening provided in at least one of the major surfaces; an electrolyte in contact with the zinc electrode and the air electrode; and means for directing a flow of reaction air from a scrubber across the outer faces of two adjacently interfacing air electrodes; the battery further having cooling-air, flow-directing means comprising a pair of spaced-apart thin plates positioned between adjacent cells, each thin plate having similar dimensions to the major surfaces and means being provided for forcing cooling-air to flow between the pair of thin plates, the outer faces of the thin plates being arranged to be in contact with and to cool the reaction air.
