PURPOSE: To utilize fuel, at very high percentage, used in a stack of a fuel cell without a voltage loss or without high parasitic power requirement, by supplying the fuel of a plurality of first fuel cells converting fuel into electricity and exhaust, and collecting exhaust or performing partial feedback. CONSTITUTION: A raw fuel supply 12 is connected to an inlet multi-branch pipe 20 via a first fuel converter 14 including a reformer and a shift reactor. The inlet multi-branch pipe branches in nine separation lines 22, to be connected to a fuel cell 25 in a main fuel stack 24. 1% exhaust of the fuel cell is extracted through a line 32 by a blower 36, for reuse in a system, to be returned to a line 16. The percentage of exhaust is advanced via a line 34 to a second converter 40 for converting unreaction methane and vapor into hydrogen, and a product of the converter is advanced to a ventilating stack 42. Further, exhaust of the ventilating stack is discharged from a system via a line 46. |
