  • Patent number: 8277623
    Abstract: The present invention relates to a conductive diamond electrode, comprising a substrate having a plurality of convex and concave part disposed over the entire surface of the conductive diamond electrode, and a diamond film coated on the surface of said substrate, wherein the width of each convex part of said convex and concave part is in a range from 0.2 mm to 1 mm. The present invention can provide a conductive diamond electrode, applying a thin film of conductive diamond and a thick substrate, being less expensive than a self-supported type conductive diamond electrode and also having mechanical strength enough to be used in the zero-gap electrolysis, functioning stably for a long time with smooth water supply or gas liberation, and an ozone generator using the conductive diamond electrode.

  • Publication number: 20100084259
    Abstract: The present invention offers an operation method of an ozonizer and an ozonizer apparatus to improve ozone gas purity and to achieve long and safety electrolysis operation in such manner that, during normal operation of the ozonizer, ozone gas is generated at the anode in the anode compartment and hydrogen gas is generated at the cathode in the cathode compartment; and only when the ozonizer is stopped and operation is switched to protective current operation during which minute electric current is supplied to protect said anode, oxygen-containing gas is supplied to said cathode compartment after electrolyte and hydrogen gas in said cathode compartment are all drained out, so that said cathode is made function as a gas electrode for oxygen reduction reaction, using said cathode as a reversible electrode with two functions as a gas generation electrode and a gas electrode, thereby during normal operation, ozone is generated efficiently, and during the protective current operation, when safety is a key issue, h
