摘要： The invention relates to an electrolysis cell of the single-element type design for chlor-alkali electrolysis plants, comprising an anode compartment and a cathode compartment, each of the two compartments containing an electrode connected to the rear wall of the respective compartment by means of parallel bars. The electrodes are thus subdivided into several sections. In accordance with the invention, at least one of two electrodes is provided with a curved shape in each section, this curved section protruding towards the opposite electrode and pressing a membrane area against the opposite electrode. According to a preferred embodiment, the curved shape of the various electrode sections is obtained by means of springs.

摘要： The invention relates to a method for producing electrically conducting nickel oxide surfaces made of nickel-containing material. According to said method, the nickel surface is first degreased and is then roughened for approximately ten minutes in a solution containing about one percent of hydrochloric acid, said process being accelerated by adding hydrogen peroxide solution, resulting in the electrolyte turning green. The nickel surface is briefly wetted, the nickel material is introduced into a solution of 3.5 molar lye to which about ten percent of hydrogen peroxide is added and is kept therein for ten minutes, and the resulting nickel hydroxide surface is dehydrated in a subsequent thermal process and is then further oxidized to obtain nickel oxide. The invention further relates to a conductive boundary layer that is produced according to said method, the electrodes therefrom, and the use thereof in chlorine-alkali electrolysis processes, in fuel cells and storage batteries.
