Abstract

Электролизер и способ управления электролизером, содержащим горизонтальный катод (4) из электропроводного материала и заделанные в катод в качестве токоотводов горизонтальные катодные стержни. Электролизер также содержит ошиновку. Когда указанный катод содержит по меньшей мере один вертикальный токоотвод (6), распространение электрического тока становится более равномерным, что улучшает работу электролизера.
