Claims (1)
- <div class="application article clearfix printTableText" id="claims"> <p lang="en"> Claims<br><br> 1. A method for operating an electrolysis cell, where electrical current is lead into the cell via an anode arrangement arranged in the upper part of the cell, through an electrical conducting electrolyte and further through a substantially horizontal cathode characterised in that electric current is lead out of the cell by at least one substantial vertically arranged current outlet that has a downwardly tapered section and that electric current is collected in the cathode by one inner, horizontally extending part of the said current outlet where said extending part is embedded in the cathode.<br><br> 2. A method in accordance with claim 1, where the cathode comprises at least one collector bar integrated therein, where current is conducted out of the cathode by at least one horizontal end of said collector bar,<br><br> characterised in that the amount of current conducted out of the cathode at the at least one vertical outlet is a pre-calculated proportion of that of the horizontal end of the collector bar.<br><br> 3. A method in accordance with any one of claims 1 -2,<br><br> characterised in that the amount of current conducted out of the vertical outlet is in the range of 20-100 % of the total current, where 100 % represent a design with only vertical outlets.<br><br> 4. Electrolysis cell comprising a substantially horizontal cathode structure of an electronic conducting material and further having integrated current leads such as horizontal collector bars embedded therein, the cell further comprising a bus bar system,<br><br> characterised in that said cathode structure comprises at least one substantial vertical electrical current outlet connected to the bus bar system where said current outlet has a downwardly tapered section and where the outlet is provided with at least one horizontal current lead portion that is embedded in the cathode material and in electrical contact with same.<br><br> 9<br><br> Received at IPONZ 23 December 2010<br><br> 5.
