Abstract
A cell, particularly a membrane cell, that will generally be oriented in an at least substantially vertical positioning, is provided with an array of blade electrodes. The blade electrodes are Delta shape in cross-section, having a flat back face and forwardly sloping sides meeting at a forward edge. Such electrodes can be secured to a current distributor bar, typically on a flat front face of the bar. The forward edge of an electrode blade may be placed opposite a counter electrode of the same or different structure, with a membrane separator usually interposed therebetween. Electrical connection can be made to the electrode blades from the distributor bar, and to the distributor bar through boss electrical connectors. Baffles, which may also be secured to the distributor bar, help establish a front chamber, containing the electrode blades, in front of the baffles, and a back chamber behind the baffles. Electrolyte circulates through the front chamber and recirculates through the back chamber.
