1. A modular zinc-air cell for use in a multi-cell metal-air battery comprisinga housing having two outer major surfaces and two spaced-apart inner walls, said inner walls defining a first inner chamber for containing therein a zinc electrode, and in conjunction with said outer major surfaces defining two outer chambers for receiving reaction air;

  • two generally planar, gas-permeable, but liquid-impermeable air electrodes, each of said electrodes being installed in a window-like opening provided in each of said inner walls;

    an electrolyte in contact with said zinc electrode and said air electrodes; and

    means for directing a flow of said reaction air into an inlet provided in a first outer side surface of said housing through both of said outer chambers substantially in a uniform flow distribution across the outer faces of both of said air electrodes, and out of an outlet provided in an opposite outer side surface of said housing.
