A metal oxide-hydrogen battery including an outer pressure vessel that contains a plurality of cell modules disposed in side-by-side relations. Adjacent cell modules are separated by heat transfer members that transfer heat from the cell modules to the outer vessel. Each heat transfer member includes a generally flat body or fin which is disposed between adjacent cell modules and a peripheral flange which is located in contact with the inner surface of the pressure vessel. The width of each cell module is greater than the length of the flange so that the flange of each heat transfer member is out of contact with the adjacent heat transfer member. The flanges are constructed and arranged to exert an outward radial force against the pressure vessel. Tie bars serve to clamp the cell modules and heat transfer members together in the form of a stack which is inserted into the pressure vessel.
In a metal oxide hydrogen battery, an outer pressure vessel, a plurality of cell modules disposed in side-by-side relation in said vessel, a heat transfer member disposed between adjacent cells modules, each heat transfer member including a generally flat fin disposed between adjacent cell modules and a peripheral flange extending from the periphery of said fin and disposed in engagement with the inner surface of said pressure vessel, the width of said cell modules being greater than the longitudinal length of said flanges whereby the outer end of each flange is disposed out of contact with adjacent heat transfer members, and connecting means for connecting the cell modules and heat transfer members in side-by-side relations as a stack.
In a metal oxide-hydrogen battery, an outer pressure vessel including a generally cylindrical metal shell, a plurality of cell modules dispose in said metal shell, a plurality of heat transfer members each including a generally flat fin disposed between each pair of adjacent cell modules and having a peripheral flange disposed in engagement with said metal shell, the width of said cell modules being greater than the length of the flanges of said heat transfer members whereby each flange is disposed out of contact with the adjacent heat transfer member, clamping means for clamping the cell modules and said heat transfer members together in side-by-side relations as a stack, and means for permitting said flange to follow radial expansion of said pressure vessel.
In a metal oxide-hydrogen battery, an outer pressure vessel, a group of cell modules disposed in side-by side relations in said pressure vessel, a plurality of heat transfer members, each heat transfer member including a generally flat fin disposed between adjacent cell modules and each heat transfer member including a peripheral flange extending generally longitudinally from the peripheral edge of each fin and disposed in engagement with the inner surface of said pressure vessel, each flange being provided with a plurality of longitudinally extending circumfrentially spaced slits, the width of each cell modules being greater than the length of each flange whereby the outer end of each flange is disposed out of contact with the adjacent heat transfer member, and clamping means for clamping the cell modules and heat transfer member in side-by-side relation as a stack.
