The generation of oxygen, hydrogen, and ozone from water with innovative proton exchange membrane water electrolysis  and their application is addressed. The integration of oxygen, hydrogen, and ozone on specific disease cure and prevention, fishery farming, agricultural irrigation and food preservation are proved to more efficiently than individually . Our invention will be the best green invention in this century.

Traditionally, IrO2 and PbO2 are utilized as anode materials for producing H2/O2 and H2/O2(O3) only at low and high voltages, respectively. In this study, it is found that even small amount of IrO2 addition, anode with PbO2 is capable to produce hydrogen at low voltage. Additionally, PbO2 anode catalyst with IrO2 possess better resistivity after switching off of the power and restarted.

Unlike companies with 2-in-1 or 3-in-1 PEMWE applied to in energy storage and disinfection, respectively, the application of high purity hydrogen, high pressure oxygen (w/o medical grade ozone) from with innovative proton exchange membrane water electrolysis on fishery farming, agricultural irrigation, specific disease cure and prevention, and food preservation has been addressed and patented.
