Abstract

Una celda de diseño avanzado para la producción de aluminio mediante la electrolisis de un componente de aluminio disuelto en un electrolito fundido, tiene un cátodo (30) de configuración de drenado, y al menos un ánodo que no es de carbono (10) enfrentado al cátodo ambos cubiertos por el electrolito (54). La parte superior de la celda contiene una cubierta de aislamiento térmica que se puede mover (60) colocado justo sobre el nivel del electrolito (54). Preferiblemente, el cátodo (30) contiene una masa de cátodo (32) soportada por un portador de cátodo (31) fabricados de material conductivo eléctricamente que sirve también para la distribución uniforme de corriente eléctrica a la masa del cátodo (32) de los alimentadores de corriente (42) que conecta el portador de cátodo (31) al barra colectora negativa.
