<P>PROBLEM TO BE SOLVED: To provide an air control method capable of supplying air without delay to a fuel cell. <P>SOLUTION: A delay computing means 46 is incorporated in a control part 4, and calculates a feedback value from: an air flow rate GAIR detected with an air flow rate sensor 7; and the shortage amount STAIRDLY of air flow rate inside a stack of a fuel cell. A rotational speed F/B value calculating means 43 calculates a rotational speed F/B value NCMDFB based on the feedback value calculated with the delay calculating means 46, added to an air pump rotational speed base value NCMDBS calculated with a rotational speed command value calculating means 42 to calculate an air pump rotational speed command value NCMD. <P>COPYRIGHT: (C)2009,JPO&INPIT |
