Zusammenfassung:A fuel cell for the electrolytic production of hydrogen chloride and the generation of electric energy from hydrogen and chlorine gas is disclosed. In typical application, the fuel cell operates from the hydrogen and chlorine gas generated by a chlorine electrolysis generator. The hydrogen chloride output is used to maintain acidity in the anode compartment of the electrolysis cells, and the electric energy provided from the fuel cell is used to power a portion of the electrolysis cells in the chlorine generator or for other chlorine generator electric demands. The fuel cell itself is typically formed by a passage for the flow of hydrogen chloride or hydrogen chloride and sodium chloride electrolyte between anode and cathode gas diffusion electrodes, the HCl increasing in concentration in the flow direction. Hydrogen and chlorine gases are supplied respectively through the anode and cathode gas diffusion electrodes to the electrolyte of hydrogen chloride in the region between the electrodes. The disruptive effect of chloride ions on the hydrogen gas to hydrogen ion reaction is inhibited.
