BATTERY, GAS DEPOLARIZED ELECTROCHEMICAL CELL AND BIPOLAR ELEMENT FOR THE BATTERY

摘要

A battery comprising an inert container housing a plurality of corrosion resistant gas depolarized metal cathode elements (1) in hollow box-like form and consumable anode elements (5) in spaced relationship with said cathode elements. At least one wall of each cathode element has a gas-permeable porous cathode (4) formed of sintered particles impregnated with a catalyst and, on the inside, with hydrophobic resin. The consumable anode elements (5) are mounted on non-consumable metal supports (2) so as to be removable (with or without their supports) and replaceable in the container. In operation, depolarizing gas is fed inside the cathode elements and an electrolyte is maintained between the facing cathodes and anodes.
