<P>PROBLEM TO BE SOLVED: To secure a sufficient amount of power generation even at a region, or the like at a high altitude by performing the appropriate correction of the air supply flow rate of a fuel cell unit to a change in atmospheric pressure by an inexpensive control configuration for detection, by estimating the atmospheric pressure without providing any exclusive pressure sensors, or the like for measuring the atmospheric pressure. <P>SOLUTION: The atmospheric pressure is estimated from the characteristic map of the atmospheric pressure of an estimation circuit 13 to the detected secondary pressure, by utilizing the detected secondary pressure of the pressure sensor 3 for detecting secondary pressure at the side of the fuel cell unit 8 of a regulator 1 changing with the atmospheric pressure, thus correcting the amount of air supply of the fuel cell unit 8 according to variations in the atmospheric pressure based on the estimated result. <P>COPYRIGHT: (C)2007,JPO&INPIT |
