摘要： Disclosed is an energy efficient electrolyzer for the production of hydrogen. The electrolyzer consists of an inner container, a plurality of electrolytic cells within the container and means for passing electric current in series through the electrolytic cells. Each cell consists of the anode half of one inert impervious conducting bipolar plate, in contact with an inert conductive anode bed of large surface area separated from the facing cathode half of another inert impervious conducting bipolar plate by a porous insulating separator. The anode is impregnated with an anolyte of about 10 to about 60% aqueous sulfuric acid saturated with sulfur dioxide and the cathode is bathed in a catholyte of about 10 to about 60% aqueous sulfuric acid. The anode is preferably carbon pellets which have been obtained from vegetable matter and which contain about 1 to about 5% platinum.

摘要： A dense, electronically conductive interconnection layer 26 is bonded on a porous, tubular, electronically conductive air electrode structure 16, optionally supported by a ceramic support 22, by (A) forming a layer of oxide particles of at least one of the metals Ca, Sr, Co, Ba or Mg on a part 24 of a first surface of the air electrode 16, (B) heating the electrode structure, (C) applying a halide vapor containing at least lanthanum halide and chromium halide to the first surface and applying a source of oxygen to a second opposite surface of the air electrode so that they contact at said first surface, to cause a reaction of the oxygen and halide and cause a dense lanthanum-chromium oxide structure to grow, from the first electrode surface, between and around the oxide particles, where the metal oxide particles get incoporated into the lanthanum-chromium oxide structure as it grows thicker with time, and the metal ions in the oxide particles diffuse into the bulk of the lanthamum-chromium oxide structure, to provide a dense, top, interconnection layer 26 on top of the air electrode 16. A solid electrolyte layer 18 can be applied to the uncovered portion of the air electrode, and a fuel electrode 20 can be applied to the solid electrolyte, to provide an electrochemical cell 10.
