Abstract
The present invention generally relates to cathodes used to produce chlorine gas from gaseous hydrogen chloride. The cathode comprises a cathode electrolyte comprising Fe(II) compounds and Fe(III) compounds in contact with an electron conductor. A reactor comprises a reactor solution comprising an oxidant in fluid contact with the cathode electrolyte. The fluid contact of the reactor solution with the cathode electrolyte allows the cathode electrolyte rich in Fe(II) compounds to be transferred to the reactor and combined with the reactor solution and the reactor solution rich in Fe(III) compounds to be transferred from the reactor to the cathode electrolyte after the oxidant of the reactor solution reacts with the electrolyte rich in Fe(II) compounds to form the reactor solution rich in Fe(III) compounds.
