Cathode useful in an electrolytic cell comprises at least two cathode blocks with a cross section comprising upper or lower part in a rectangular shape and other part in a trapezoidal shape

摘要

Cathode (22) comprises at least two cathode blocks. Either the upper or the lower part of the cross section of at least two cathode block (34) is designed in a rectangular shape, and the other part of the cross section of the cathode block is designed in a trapezoidal shape. At least one of the cathode blocks of the trapezoidal shaped part of the cross-section adjoins with its base at the rectangular shaped part of the cross section. Cathode (22) comprises at least two cathode blocks. Either the upper or the lower part of the cross section of at least two cathode block (34) is designed in a rectangular shape, and the other part of the cross section of the cathode block is designed in a trapezoidal shape. At least one of the cathode blocks of the trapezoidal shaped part of the cross-section adjoins with its base at the rectangular shaped part of the cross section. At least one other adjacent cathode block of the trapezium-shaped designed part of the cross-section adjoins with its cover side at the rectangular designed part of the cross section.
