<p>An apparatus is provided for dissociating carbon and oxygen from carbon dioxide molecules. The apparatus includes a thin plate made of a solid permeable ion-conducting membrane having a partial coating of platinum on a first side and ruthenium oxide on a second. An electric potential is applied between two surfaces of the membrane and the membrane is heated by a heating element. Carbon dioxide gas is brought into contact only with the negatively charged first side of the membrane. The oxygen atoms are put under an electric field, separate from the carbon atoms and enter the membrane, and become oxygen ions. The ions are transported across the membrane to the positively charged side, where they lose their negative charge and exit the membrane as pure oxygen. The carbon does not pass through the membrane and is left behind. The carbon is detached from the membrane and collected as powder for use or disposal.</p> |
