<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of keeping output performance in a high state by eliminating air flow shortage by limitation of torque-revolutions of a compressor driving motor without increasing the size of a motor. <P>SOLUTION: This fuel cell system includes: a fuel cell body 1 for generating power by supply of hydrogen (fuel gas) and air (oxidizer gas); a hydrogen system (fuel gas supply means) for supplying hydrogen to the fuel cell body 1; and an air system (oxidizer gas supply means) quipped with a compressor motor driven by power generated by the fuel cell body 1, and an air compressor 11 driven by the compressor motor, and used for supplying air to the fuel cell body 1. In the fuel cell system, the revolutions and torque of the compressor motor is estimated by a controller (control means) 43, and the operation pressure of the fuel cell system is set in response to the estimated revolutions and torque of the compressor motor. <P>COPYRIGHT: (C)2007,JPO&INPIT |
