METHOD FOR ELECTROCHEMICALLY REMOVING HYDROGEN FROM A REACTION MIXTURE

摘要

The invention relates to a method for electrochemically removing hydrogen from a hydrogen-containing reaction mixture R by means of a gas-tight membrane electrode assembly which comprises at least one selectively proton-conducting membrane and at least one electrode catalyst on each side of the membrane, at least part of the hydrogen contained in the reaction mixture R being oxidized on the anode catalyst to protons on the retentate side of the membrane and the protons, after passing the membrane and on the permeate side on the cathode catalyst, I being reduced to hydrogen and/or II being reacted with oxygen to water, the oxygen coming from an oxygen-containing flow O which is being contacted with the permeate side of the membrane. The invention further relates to a reactor which is equipped with at least one membrane electrode assembly.
