Abstract: With the help of a method for production of a gaseous diffusion electrode from a silver catalyst on PTFE-substrate, it is endeavored to achieve results which can be reproduced, by avoiding the disadvantages of the state-of-the-art technology, whereby this is achieved in that the porous system of the silver catalyst is filled with a wetted fluid; a dimension-stable solid body with a grain size above that of the silver catalyst is mixed below the silver catalyst; the thus compression-stable mass is shaped into a homogenous catalyst band in a calender; and in a second calender step, an electrically conductive conductor material is imprinted into the catalyst band.

Abstract: The invention relates to a method for producing electrically conducting nickel oxide surfaces made of nickel-containing material. According to the 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, the 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 the method, the electrodes therefrom, and the use thereof in chlorine-alkali electrolysis processes, in fuel cells and storage batteries.

Abstract: The invention relates to a method for the production of a gas diffusion electrode from a silver catalyst on a PTFE-substrate. The pore system of the silver catalyst is filled with a moistening filling agent. A dimensionally stable solid body having a particle size greater than the particle size of the silver catalyst is mixed with the silver catalyst. Said compression-stable mass is formed in a first calendar in order to form a homogenous catalyst band. In a second calendar, an electroconductive discharge material is embossed in the catalyst band, and heating takes places between the first and the second calendar by means of a heating device, wherein at least parts of the moistened filling agent are eliminated. The invention also relates to a gas diffusion electrode which is produced according to said method.
