1. A metal-air battery cell having an anode support comprising:
- an elongated lower frame member of a generally inverted U-shape in cross-section upon which an anode rests when inserted into said anode support, said lower frame member having apertures extending from the chamber defined by said general inverted U-shape upwardly toward said anode along said frame member; and
a pair of upright, elongated side rails spaced apart, one from the other whereby each extend from an end of said lower frame member, with each side rail providing lateral support for an anode.

Abstract
A bipolar battery assembly of the consumable metal anode type is described. Contact between internal battery elements is now enhanced by air assisted, internally exerted compressive force. Battery elements are constructed in modular manner that assists in the ease of battery assembly and disassembly. Furthermore, ease of anode replenishment is maintained. A multitude of individual cells can now be joined together in an efficient bipolar assembly cell stack for augmented electrical energy generation. In addition to being bipolar, the battery is of rugged construction, providing for dependable, long-life operation that is desirably maintenance-free.

4. In a metal-air battery cell for use in a bipolar battery, the improvement comprising an anode current collector assembly containing
a solid current collector plate member for planar face-to-face contact with a plate-like anode; -
conductive and compressible members affixed to said plate member and extending therefrom directionally away from said anode; and a flexible, peripheral diaphragm member in a firm engagement around said current collector plate member but spaced apart from, and out of contact with, said anode, said diaphragm member extending initially away from said plate member in like direction as said conductive and compressible members and then directionally into sealing engagement with a container for said battery. - View Dependent Claims (5, 6, 7, 8)

9. In a cell having a current collector surrounded by a diaphragm, the improvement comprising an axially flexible diaphragm of
a frame member having size at least substantially as large as the perimeter of said current collector; -
a first raised edge element positioned rearwardly of said frame member and extending vertically and outwardly from said frame; an at least essentially flat front facing on said first raised edge element for face-to-face engagement with at least a portion of a current collector; and a second, segmented raised edge element positioned forwardly of said frame member, having a first segment projecting outwardly at an angle from said frame member and then extending to a vertically and outwardly projecting front edge second segment positioned around the periphery of said first segment. - View Dependent Claims (10, 11)
