Abstract:
An aqueous electrolysis cell for generation of gas comprising an electrolysis container having an anode chamber and a cathode chamber separated from each other by a membrane, said cell being adapted to generate by electrolysis reaction of water oxygen and ozone in said anode chamber and hydrogen in said cathode chamber, said cell further comprising:an anode having permeability to gas and water and fitted on said membrane in such a manner that one surface of said anode is in contact with one surface of said membrane;a cathode having permeability to gas and water and fitted on said membrane in such a manner that one surface of said cathode is in contact with the other surface of said membrane;a first sealing element fitted on said anode and said membrane to surround and seal circumference of said anode, one surface of said first sealing element being in tight contact with said one surface of said membrane, said first sealing element having an opening communicating with said anode;an anode current collector plate having one surface in tight contact with the other surface of said first sealing element, said anode current collector plate having a through-hole communicating with said opening of said first sealing element;a second sealing element having one surface in tight contact with the other surface of said anode current collector plate, said second sealing element having an opening communicating with said through-hole of said anode current collector plate;said anode, said opening of said first sealing element, said through-hole of said anode current collector plate and said opening of said second sealing element defining in said anode chamber a flow passage for gas and liquid; a conduit connecting said flow passage to a separator for collecting gas generated in said anode chamber;a flange fastened to said conduit, said second sealing element, said anode current collector plate and said first sealing element for providing tight contact therebetween, said flange having means for fastening said conduit to the separator; anda casing for defining said anode chamber and said cathode chamber and having a bottom wall.
