Abstract
A process and apparatuses for producing hydrogen peroxide which provides good current density and production efficiency from an electrolytic liquid having an exceedingly low conductivity, such as ultrapure water. An electrolytic cell main body containing an anode,and a cathode,which are electrically connected to each other via ion-exchange resin particles,is used to conduct electrolysis while maintaining the electrical connection. High-purity, high-concentration hydrogen peroxide is produced at a high current efficiency even when the electrolytic liquid has an exceedingly low conductivity.
