Abstract
The power generation system includes a reformer and two fuel cell stacks. The reformer and the fuel cell stacks are provided in series. Fuel gas produced by the reformer is introduced to a first anode of the first fuel cell stack. Gases discharged from the first anode are directly introduced to a second anode of the second fuel cell stack. Air is introduced to a first cathode of the first fuel cell stack. Gases discharged from the first cathode are cooled by a cooling device and then introduced to a second cathode of the second fuel cell stack. Gases discharged from the second anode and gases discharged from the second cathode are introduced to a heating chamber of the reformer. Gases discharged from the heating chamber are introduced to a steam generator to produce steam used for reformation and then recirculated to the first cathode.
