Abstract: The present invention is directed to an apparatus for producing hydrogen peroxide, comprising one or more electrochemical cells, the apparatus further comprising at least one electrically conductive porous gas transport layer disposed next to a cathode gas diffusion layer, the gas transport layer being configured to deliver a flow of oxygen-containing gas towards the cathode gas diffusion layer and being configured to collect current, further including water which is configured to flow through the porous gas transport layer.

Abstract: The invention is directed to an electrochemical cell for production of chemicals from a gas-phase reactant in a liquid environment. The electrochemical cell has a membrane electrode assembly configuration and is comprised of an anode, an ion exchange membrane and a cathode. The membrane electrode assembly is in direct contact with a liquid solution to facilitate extraction and handling of the produced chemicals, and the gas reactant is delivered through the liquid to the membrane electrode assembly. The present invention relates to a process and electrochemical cell for use in the synthesis of chemicals. The present invention relates to the electrocatalysts used and their incorporation into a membrane electrode assembly, MEA. The present invention also relates to the electrodes used in a membrane electrode assembly, in particular the gas diffusion layer, and a method for transport of gas-phase reactants into a liquid-immersed membrane electrode assembly.
