PROBLEM TO BE SOLVED: To provide structure reducing fuel consumption by enhancing efficiency while increasing transient responsiveness in a constitution including a fuel cell and a converter installed between a vehicle driving motor and an auxiliary machine motor in a fuel cell system.SOLUTION: The fuel cell system 10 includes: a converter 24 boosting the output voltage of a fuel cell stack 12 and then supplying it to a first inverter for a driving motor 14 and second inverter for an air compressor motor 20; a voltage acquisition means 54; and a converter control means 56. The voltage acquisition means 54 acquires the request voltage of the air compressor motor 20 according to a target air compressor motor torque based on the acceleration request of the air compressor motor 20. The converter control means 56 compares the request voltage of the air compressor motor 20 with that of the driving motor 14, sets a boosting ratio of the converter 24, and controls the converter 24. |
