Abstract

Provided is an electrochemical cell for generating hydrogen peroxide (H2O2) directly from water, and an application thereof. The electrochemical cell includes: water-soluble electrolyte; an electrode structure A, in which hydrogen peroxide is generated by oxidizing water containing city water (CW) or electrolytes when voltage of time dependant polarity is applied; and an electrode structure B, in which hydrogen peroxide is generated by reducing water of the water-soluble electrolyte when the voltage of time dependant polarity is applied, wherein the polarity reversal of the voltage Ve is performed periodically or non-periodically according to the time between positive (+) voltage and negative (-) voltage.
