A cathode structure of length x and width y (with x > y) for an electrolytic cell comprising a plurality of parallel cathode blocks of length a and width b (with a > b) extending over substantially the whole length x of said cell (with y ~ a), said cathode structure comprising a majority of so-called standard cathodes of height cS and a minority of so-called tall cathodes of height cT, the flat upper surface of said standard cathodes forming at least one so-called high portion at a height cS, and the flat upper surface of said tall cathodes forming at least one so-called high portion at a height cT, wherein cT > cS, and wherein each high portion has a width yH ~ y, and each low portion has a width yL ~ y, and wherein each low portion extends over at least two adjacent standard cathode blocks such xL ≥ 2 b(xL being the length of the low portion). |
