FUEL CELL POWER GENERATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a fuel cell power generation device in which while avoiding reduction of energy efficiency and reduction of durability, operation can be stabilized by rapidly eliminating combustion failure in a combustion part.SOLUTION: In the fuel cell power generation device, a reformer 4, a fuel cell part G, and the combustion part 6 in which combustible components in exhaust reforming gas are combusted are installed in a housing container 10. The reformer 4 carries out reforming treatment of a raw fuel by using a combustion heat generated by combustion at the combustion part 6. The fuel cell power generation device includes: a combustion failure detecting means 24 to detect combustion failure of the combustion part 6; a power generation output adjusting means 8 to freely adjust power generation output of the fuel cell part G; and a control means 9 to control operation of the power generation output adjusting means 8 so that a power generation output of the fuel cell part G is changed and adjusted to a reduction side in such a state that a raw fuel supply amount and a steam supply amount to the reformer 4 and an oxygen containing gas supply amount to the fuel cell part G are not changed in the case combustion failure is detected by the combustion failure detecting means 24.
