CA 2306231

An electrochemical cell module (10) has an outer shell (14) of conductive material defining a cavity, and electrolytic membrane (20) located in the cavity, first (21) and second (23) pervious electrodes located on opposite sides of the membrane (20), and a seal member (22) located between the second electrode (23) and the outer shell (14). Contacts (40) for connecting a power source across the electrodes are provided on the second electrode (23) and on the outer shell (14) on the same side of the membrane (20) as the second electrode (23), and the outer shell (14) provides a current collector for the first electrode (21) without requiring any external leads across the module.

L'invention concerne un module à cellule électrochimique (10) qui comprend une enveloppe extérieure (14) fabriquée dans un matériau conducteur et définissant une cavité, une membrane électrolytique (20) placée à l'intérieur de cette cavité, une première (21) et une seconde électrodes (23) perméables disposées sur les cotés opposés de ladite membrane (20), et une garniture d'étanchéité (22) placée entre la seconde électrode (23) et l'enveloppe extérieure (14). Des contacts (40), connectés à une source d'alimentation au-dessus desdites électrodes, sont en outre prévus sur la seconde électrode (23) ainsi que sur l'enveloppe extérieure (14), sur le même coté de la membrane (20) que la seconde électrode (23), l'enveloppe extérieure (14) constituant un collecteur de courant pour la première électrode (21), ce qui évite ainsi d'utiliser des conducteurs extérieurs au-dessus dudit module.
