Patent 7431818 was granted and assigned to United Technologies on October, 2008 by the United States Patent and Trademark Office.
A fuel system for an energy conversion device includes a deoxygenator system with an electrochemical conversion system to remove oxygen from fuel through conversion of the oxygen to water. The electrochemical conversion system is located within a fuel flow. On the fuel side ½O2+2H++2e−=>H2O while on the reverse side the opposite reaction occurs. From the electrochemical conversion system the water is then collected and/or expelled from the system.
