  • Fuel cell power generating system with two fuel cells of different types and method of controlling the same
    Patent number: 7749626
    Abstract: A solid oxide fuel cell stack generates power by an electrochemical reaction of oxygen with hydrogen or hydrogen and carbon monoxide in a reformed gas which is produced from a natural gas by a reformer, and supplies waste heat and an anode exhaust gas containing steam to the reformer. The reformed gas produced by the reformer is reduced its CO concentration through a CO shift converter and a CO selective oxidizer. A polymer electrolyte fuel cell stack generates power by an electrochemical reaction of oxygen with hydrogen contained in a reformed gas which is emitted through the CO selective oxidizer with reduced CO concentration and with condensed moisture by a condenser.
