Abstract

A method and apparatus for carrying out an electrolytic process produces clean gases, such as oxygen and hydrogen. For this purpose, a porous diaphragm is arranged between the cathode and the anode of an electrolyzer, and a liquid electrolyte is fixed in the pores of the cathode and anode. A first gas chamber adjoins the cathode, while a second gas chamber adjoins the anode, and an educt chamber is separated from the first gas chamber by a membrane. An aqueous, non-corrosive solution of salts of inorganic and organic acids or mixtures of water with organic additives is used as an educt, which, compared with the electrolyte, has a higher partial water vapor pressure.
