Electrochemical production of hydrogen peroxide

This invention relates to a process and reactor for the electrochemical production of hydrogen peroxide. The process comprises producing protons at an anode, transporting produced protons through a cation exchange membrane into catholyte, producing peroxide anions in a cathode membrane assembly comprising a gas diffusion electrode and an anion exchange membrane adjoined to said gas diffusion electrode and in contact with said catholyte, which produced peroxide anions migrate at least in part into said catholyte, and combining protons and peroxide anions in said catholyte to form hydrogen peroxide
