Abstract
An electrolysis apparatus for electrolysis of water comprises a series of cells, each cell including a substantially open porous anode plate and a substantially open porous cathode plate with a solid electrolyte membrane therebetween. First and second flow passages extend through the cells, with the first flow passage comprising bores extending through the centers of the cathode plates, the anode plates, and the membranes; the bores in the cathode plates being fitted with annular sealing gaskets. The second flow passage also comprises bores extending through the cathode plates, the anode plates, and the membranes, with the bores in the anode plates being fitted with annular sealing gaskets. A seal is provided at the outside perimeter of the cathode plate, to prevent the escape of fluid, containing hydrogen, therefrom. During operation, water is driven into the first flow passage. The water diffuses through the anode plate from the central bore, and partial electrolysis occurs. Water which reaches an outer perimeter of the anode plate, without electrolysis, drains from the assembly, providing a means for cooling. Ions formed can migrate to the cathode plate, whereat hydrogen gas is …
