Abstract
An electrochemical cell is provided with means for isolating and segregating the mercury droplets formed during the electrochemical consumption of amalgamated anodic materials. The segregating means comprises amalgamable metal sheet, preferably of expanded surface area as provided by grids of screening or expanded metal lath, in contact and adjacent to the inactive face of the anode. While zinc is the exemplified anode, the grid will protect other amalgamated anodes including cadmium and lead in aqueous systems, and lithium, sodium and calcium in non-aqueous systems.
