Process for operating a dual compartment anode structure

Patent ·
OSTI ID:6875804

A process is described for molten carbonate electrolyte fuel cell operation comprising: supplying hydrogen containing fuel to a fuel compartment, the fuel compartment separated from an anode reaction gas compartment by a hydrogen ion porous and molecular hydrogen and electrolyte non-porous metallic foil; dissociating the hydrogen to ionic hydrogen; passing the ionic hydrogen through the metallic foil to the anode reaction gas compartment which comprises a porous metallic anode structure adjacent the molten carbonate electrolyte; reacting in the porous anode structure the ionic hydrogen with carbonate ion producing water, carbon dioxide, and electrons; passing the produced water, carbon dioxide and two electrons to a porous metallic cathode structure on the opposite side of the molten carbonate electrolyte; supplying oxygen to an oxidant compartment which comprises the porous cathode structure; reacting in the porous cathode structure the carbon dioxide, oxygen and electrons to producing carbonate ions for passage to the cathode; and removing water from the oxidant compartment.
