  "textContent": "A solid oxide fuel cell stack (57) generates power by an electrochemical reaction of oxygen with hydrogen or hydrogen and carbon monoxide in a reformed gas (27) which is produced from a natural gas (1) by a reformer (3), and supplies waste heat and an anode exhaust gas (61) containing steam to the reformer (3). The reformed gas (27) produced by the reformer (3) is reduced its CO concentration through a CO shift converter (4) and a CO selective oxidizer (5). A polymer electrolyte fuel cell stack (9) generates power by an electrochemical reaction of oxygen with hydrogen contained in a reformed gas (38) which is emitted through the CO selective oxidizer (5) with reduced CO concentration and with condensed moisture by a condenser (39).",
