SOLID OXIDE FUEL CELL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell device that feeds raw fuel gas into a reforming section without sending the raw fuel gas at high pressure.SOLUTION: A solid oxide fuel cell device (1) includes: a fuel supply device; a water supply device (28) that supplies water for steam reforming; an oxidant gas supply device (45); a fuel cell stack (14) that generates electric power; a combustion section (18) that burns fuel gas that is left without being used for electric power generation; a fuel gas supply passage (20) that is arranged so as to surround the fuel cell stack (14); a fuel gas introducing section (90a) that is provided in a lower portion of the fuel gas supply passage (20); a vaporization section (86) that is arranged above the fuel gas introducing section (90a) and that vaporizes water; and a reforming section (94) that is provided in the fuel gas supply passage (20) and that steam-reforms raw fuel gas by use of steam. The reforming section (94) is arranged above the vaporization section (86) so as to surround an upper portion of the fuel cell stack (14).
