Abstract

A cathode assembly for an electrolytic cell including a cathode block having a second surface and a first surface. The cathode block also including at least one sealing groove opening onto its first surface and a plurality of electrical contact plugs mounted in electrical contact with the first surface of the cathode block. The cathode assembly includes at least one current supply plate in electrical contact with at least one electrical contact plug, and is connected to at least one unit for connection to an electric current source. The cathode assembly includes at least one current supply bar having a coefficient of thermal expansion substantially identical to the coefficient of thermal expansion of the current supply plate and is sealed within the at least one sealing groove while being fastened to at least one current supply plate.

Abstract

The invention relates to a cathode assembly for an electrolytic cell comprising, firstly, a cathode block (10) having a second surface (11) and a first surface (12). The cathode block (10) also comprises at least one sealing groove (13) opening onto the first surface (12) thereof and a plurality of electric contact pins (50) mounted in electrical contact with the first surface (12) of the cathode block (10). The cathode assembly then comprises at least one first current-carrying plate (20) in electrical contact with at least one electric contact pin (50), and which is connected to at least one unit for connecting to a source of electric current. The cathode assembly finally comprises at least one current-carrying bar (30) having an expansion coefficient substantially identical to the expansion coefficient of the current-carrying plate (20), which is sealed in the at least one sealing groove (13) while being attached to at least one current-carrying plate (20).
