In a method for fabricating lightweight bipolar metal-gas battery cell stacks (1), a segmented frame (21, 23) for insulating and mechanically supporting the stack (1) is fabricated of dielectric materials. Each cell (3) has associated therewith first and second frame segments (21, 23) associated with negative and positive electrodes (5, 7, respectively). Weld tabs (25, 27) are welded to the negative and positive electrodes (5, 7, respectively), and are welded together external to the cell frame (21, 23). Electrolyte is added to each cell (3), preferably as it is fabricated within the enveloping cell frame segments (21, 23). Alignment rods (34) align the stack (1) components, and assist in compression-sealing adjacent frame segments (21, 23) by means of compressing mating tongues (43) and grooves (41).

A method for constructing a multi-cell bipolar metal-gas battery stack, in which a metal and a primary gas are reactants, said method comprising the steps of: fabricating a dielectric frame generally in the shape of a hollowed-out prism having inner width and inner length dimensions defining the common width and the common length of each stacked cell; placing, within the hollowed-out portion of the frame, substantially planar solid components constituting several substantially identical stacked cells, wherein each cell comprises positive and negative electrodes separated by an electrolyte impervious layer; and electrically series-connecting adjacent cells by means of forming, outside the frame, electrical connections between oppositely polarized electrodes from adjacent pairs of cells; wherein the frame confines, within each cell, electrolyte and secondary gas generated by the positive electrode of said cell; and all of the cells have equal access to a common supply of the primary gas.
