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： An electrode comprising a substrate of a conducting metal, a coat of an electrode active substrate, and a layer interposed between the substrate and the coat to serve as a protective barrier for the substrate acquires improved durability by using, as the intermediate layer, a layer having platinum dispersed in a mixed oxide consisting of an oxide of at least one metal selected from the group consisting of titanium and tin, each having a valence of 4, and an oxide of at least one metal selected from the group consisting of tantalum and niobium, each having a valence of 5. The electrode of improved durability is produced by a process which comprises the steps of preparing a substrate of a conducting metal, depositing a solution containing salts of Ti and/or Sn, Ta and/or Nb, and Pt on the substrate, heating the resultant coated substrate under the blanket of an oxidizing gas thereby forming an intermediate layer on the substrate, and subsequently coating the intermediate layer with a layer of an electrode active substance.
