Abrégé

A configuration of electrolyzer enabling electrochemical hydrogen peroxide production is disclosed. This electrolyzer consists of an anode, a cation exchange membrane, a porous proton-conducting layer and a cathode, assembled into a dedicated housing. A voltage difference is induced between anode and cathode to drive electrochemical reactions. Oxygen-containing gas is fed to the cathode, while the anode generates protons (typically using water as a proton source). Protons generated at the anode cross a cation exchange membrane and a porous proton-conducting layer, and they combine with oxygen at the surface of the cathode electrode to generate hydrogen peroxide. Generated hydrogen peroxide is extracted through the porous proton-conducting layer, in a process that can be aided with a water flow through the proton-conducting layer, which allows for a high faradaic efficiency and throughput.
