Title (EN) METAL/OXYGEN BATTERY CONSTRUCTIONS
(FR) CONFIGURATIONS DE BATTERIES A METAL/OXYGENE
Abstract:
(EN) The cells of a multicell metal/oxigen battery construction each contain a potassium hydroxide electrolyte, a metal anode plate and a pair of oxygen permeable cathode panels, one on each side of the anode. Each cell has an electrically non-conducting housing comprising opposed faces and a peripheral rim region, with an aperture in each of the opposed faces, to which the cathode panels are sealingly fixed so as to obturate the aperture. The faces of adjacent housings are sealed to each other in confronting fluid-tight manner so as to define therebetween oxygen feeds and electrolyte drains, both the oxygen feeds and the electrolyte drains communicating externally of the cells with the cathodes.
(FR) Les éléments d'une configuration de batterie à métal/oxygène contiennent chacun un électrolyte d'hydroxyde de potassium, une plaque d'anode en métal et une paire de panneaux de cathode perméables à l'oxygène et disposés de chaque côté de l'anode. Chaque élément possède un boîtier non électroconducteur comportant des faces opposées et une zone marginale périphérique, une ouverture étant ménagée dans chacune de ces faces opposées pour permettre la fixation étanche à celle-ci des panneaux de cathode et l'obturation de l'ouverture. Les faces des boîtiers sont appliquées l'une contre l'autre de manière étanche aux fluides afin de définir entre elles des voies d'amenée d'oxygène et d'évacuation d'électrolyte, lesquelles voies communiquent avec les cathodes à l'extérieur des éléments.
