ABSTRACT:
A galvanic element in the form of a flat, high power cell, especially a ml-air-cell, which is cooled with cooling water, and can be assembled to a battery which comprises a plurality of cells. The flat cell comprises bipolar electrodes which have a consumable metal electrode in flat form as an anode, a cathode (oxygen electrode), and a liquid electrolyte. It is an object of the present invention to be able to control the temperature, especially for cooling, of each individual electrode directly by means of a medium which is independent of the liquid electrolyte. For this purpose, the bipolar electrodes are electrically interconnected, and between them is arranged a gasket which forms a cooling chamber. As a result, the heat balance and temperature of not only the anode but also of the cathode can be controlled directly.
