Abstract
A process for the electrochemical preparation of hydrogen peroxide, in particular an aqueous hydrogen peroxide solution, by the electrochemical reaction of oxygen and hydrogen in a fuel cell. By increasing the thickness of the membrane layer in a membrane electrode unit (MEU) in the fuel cell, it is possible to substantially increase the concentration of H O in the aqueous hydrogen peroxide solution obtained at the cathode.
