Abstract

Способ и усовершенствования, относящиеся к электролизеру, где указанный электролизер содержит, по существу, горизонтальный катод из материала с электронной проводимостью, имеющий далее токовые выводы, например горизонтальные стержни коллектора, встроенные в катод. В электролизере можно создать улучшенное распределение электрического тока, когда указанная система шин передает ток по меньшей мере из одной промежуточной точки указанного катода. Настоящее изобретение можно применить к электролизерам, расположенным как торец к торцу, так и бок о бок.A method and improvements relating to an electrolytic cell, wherein said electrolytic cell comprises a substantially horizontal cathode of an electronically conductive material, further having current leads, for example, horizontal collector rods embedded in the cathode. An improved electrical current distribution can be created in the electrolyzer when said bus system transmits current from at least one intermediate point of said cathode. The present invention can be applied to electrolyzers, located both end to end, and side by side.
