1. A metal inert anode for producing aluminium by the electrolysis of a melt which has multiple electrochemically active anode elements, current distributors and a current conductor, wherein:
the anode contains no less than two vertical or inclined fins protruding from the bath,
the anode is designed to be positioned horizontally, and
the anode is made in a form of a perforated structure with through-openings distributed across the anode, the degree of anode perforation being 15-35% such that an area of a through-opening is 10-100 cm2.
