INTERNAL BOX FOR AN ELECTROLYTIC MANGANESE CELL, INCLUDING SUPPORTING FINGERS, AND ASSOCIATED METHOD AND CELL

摘要

The invention relates to an internal box (16) for an electrolytic manganese cell, of the type comprising: a plurality of anode frames (66); a plurality of cathode frames (64) placed between the anode frames (66); a plurality of diaphragms (68) disposed between each cathode frame (64) and each anode frame (66); and a clamping assembly (72) for holding the cathode frames (64), anode frames (66) and diaphragms (68) against one another, each anode frame (66) having an inner anode-receiving compartment (144) delimited at the bottom by a bottom cross-member (142). The anode frame (66) includes a plurality of disjoint supporting fingers (146) projecting upwards from the bottom cross-member (142), and the diaphragms (68) next to the anode frame (66) are applied laterally against the supporting fingers (146).
