Electrolytic Ozone Generator with Membrane Electrode

Abstract

An electrolytic ozone generator with membrane electrode includes a proton exchange membrane ( 2 ), an anode electrocatalyst layer ( 3 ), an anode diffusion layer ( 4 ), a flow field plate ( 5 ), a cathode structure ( 1 ) and a frame body ( 6 ). The frame boy ( 6 ) has a frame sealing groove ( 11 ) therein. A seal ( 7 ) is provided in the frame sealing groove ( 11 ). The frame body ( 6 ) is tightly connected with the cathode structure ( 1 ) through screws ( 9 ) so that the seal ( 7 ) is to seal the proton exchange membrane ( 2 ), the anode electrocatalyst layer ( 3 ) and the frame body ( 6 ) completely and tightly. The present invention has a simple structure, is cost-effective and provides a better seal effect to achieve mass production. After a period of operation, the electrolytic ozone generator still keeps an excellent seal, so that the electrolytic ozone generator can generate ozone steadily.
