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.

摘要： A system for pumping electrolyte through an electrolysis cell where the pressure of at least a portion of the gas generated by the electrolysis cell is used as driving force for the pumping. The system may include an electrolyte reservoir and a pumping chamber connected via an inlet conduit to receive electrolyte from the electrolysis cell and connected via an outlet conduit to flow electrolyte to the electrolysis cell. The pumping chamber is connected to the electrolysis cell to receive at least a portion of the gas generated by the electrolysis cell to elevate the pressure of the electrolyte therein and force it into the electrolysis cell.

摘要： An electrochemical gas sensor has a first gas diffusion electrode for a first reaction gas, which is inactive with respect to a second reaction gas at least in a first potential window, and a second gas diffusion electrode for the second reaction gas, which is active with respect to the second reaction gas at least in a second potential window for measuring two different gases in gas mixtures in a casing. The two gas diffusion electrodes are electronically isolated from one another, but electrically connected electrolytically to a reversibly loadable electrode and have contacts for connecting external closing circuits for adjusting the cell currents. The gas mixture is fed to the gas diffusion electrodes in series or parallel. The casing containing the electrodes is, in particular, in the form of a button cell. The reversibly loadable electrode is a Cu/CuO, Zn/ZnO or hydrogen electrode. The gas diffusion electrodes have a porous structure based on carbon or have a porous silver structure.

摘要： 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.
