摘要： A liquid-permeable gas-diffusion cathode adapted for caustic soda electrolysis in contact with an ion-exchange membrane partitioning an electrolytic cell into an anode chamber and a cathode gas chamber. Plural horizontal concave grooves and/or convex portions are provided in an interval with one another on the surface of the gas-diffusion cathode facing the gas chamber. Plural vertical concave grooves may also be provided in an interval on the surface of the cathode crossing the horizontal grooves and/or convex portions. Aqueous caustic soda solution thus formed flows downward along the grooves, etc., without covering other portions of the cathode surface, and is easily released therefrom without clogging perforations in the gas-diffusion layer of the cathode.

摘要： A gas-diffusion cathode disposed in contact with an ion-exchange membrane partitioning an electrolytic cell into an anode chamber and a cathode chamber, wherein at least one guide piece is disposed in the gas-diffusion cathode and a salt water electrolytic cell using the above-described gas-diffusion cathode. By using the above-described gas-diffusion cathode for salt water electrolysis, an aqueous caustic alkali solution formed descending in the direction of gravity in the cathode changes direction of movement by contact with a guide piece, whereby the decreased electrode performance resulting from the hindrance of the supply of raw material gas and the discharge of the gas formed caused by the retention of the descending caustic alkali solution is prevented and a large-sized electrolytic cell can be used without problems generally encountered in conventional electrolytic systems.

摘要： An electrolytic cell for producing a brine containing hydrogen peroxide is disclosed. Units for hydrogen peroxide production 3 and units for water electrolysis 2 are alternately arranged in the same electrolytic cell 1. Electrolysis is conducted while supplying hydrogen gas and oxygen gas generating in the respective water electrolysis units to a gas diffusion anode 11 and a gas diffusion cathode 13 of each unit for hydrogen peroxide production, to thereby obtain a brine containing hydrogen peroxide in a high concentration. Furthermore, because the anode of the hydrogen peroxide production units is a hydrogen gas diffusion anode having a reduced oxidizing ability, halogen ions contained in the seawater do not yield harmful halogenated organic substances.

摘要： The electrolytic cell 1 for producing alkali hydroxide or hydrogen peroxide is divided into the anode compartment 3 and the cathode compartment 4 by the cation exchange membrane 2. The cathode compartment 4 is further divided by the anion exchange membrane 6 into the solution compartment 7 containing a concentrated aqueous solution of alkali hydroxide and the gas compartment accommodating the gas cathode 8. The anion exchange membrane 6 prevents the gas cathode 8 from coming into direct or indirect contact with the aqueous solution of alkali hydroxide. This leads to the extended life of the gas cathode. The above-mentioned arrangement is effective in large-sized electrolytic cells. Thus, the present invention can be applied to industrial electrolysis which has never been achieved with the conventional gas electrode.
