<p>This invention relates to a filter press type electrolyzer for water comprising pressure-resistant decomposing cells, each of which contains an electrolyte chamber, which is divided by a diaphragm into two electrode compartments. The decomposing cells are enclosed on the outside by cell frames, which are electrically insulated from each other by an interposed sealing ring. On the sides, each cell is separated from the adjacent cells by metallic cell-separating partitions. At least three ducts extend through the cells and respectively serve to supply electrolyte and to discharge hydrogen and oxygen. Each duct is composed of sections. The sections of the ducts consist of sleeves, which are resistant to the operating conditions and insulated from each other and extend through openings in the cell-separating partitions. These openings are lined with metal rings. In accordance with the invention, the metal rings are secured to the cell-separating partitions by a gas- and liquid-tight welded joint and the sleeves are slidably fitted in the metal rings.</p> |
