SOLID OXIDE FUEL CELL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell device that rapidly raises the temperature of a reforming section while suppressing the unevenness of temperature.SOLUTION: A solid oxide fuel cell device (1) includes: a fuel supply device (38); a water supply device (28) that supplies water for steam reforming; a fuel cell stack (14); 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 a fuel cell stack (14); a heating section (64a) that is configured so as to conduct heat to the fuel gas supply passage (20); a reforming section (94) that is provided in the fuel gas supply passage (20); a combustion burner (84) that heats the heating section (64a); and an exhaust gas emission passage (21) that is arranged so as to exchange heat with the fuel gas supply passage (20) and through which exhaust gas as heated is emitted. The reforming section (94) is heated by heat that is conducted from the heating section (64a), and is heated from therearound by the heat of exhaust gas flowing through the exhaust gas emission passage (21).
