METAL-AIR CHEMICAL POWER SUPPLY Russian patent published in 1997 - IPC

FIELD: autonomous power supplies. SUBSTANCE: device has housing which has frame with holes, air cathodes, which are sealed in holes of frame, water solution of electrolyte and metal anode which is located inside housing in guiding grooves with projection which is located on same level as lower cathode edge. Upper cathode edge is located above lower cathode edge by 0.1-0.5 of its height, upper cathode edge is located below upper edge of housing by 0.1-0.5 of its height. Area of anode is 1.1-1.2 of area of cathode, depth of anode is 0.2-0.4 of space between cathodes. Volume of electrolytic chamber conforms to equation $$$, where V is volume of electrolytic chamber, K = 1.1-1.2 is design factor, A = 10-15 is empirical factor, M is weight of anode, m = 0.4-0.8 is relative usage of anode material, N is number of turns. Device housing may be made from insulating material or metal. EFFECT: increased electric and resource characteristics. 3 cl, 2 dwg
