<P>PROBLEM TO BE SOLVED: To provide a vehicle driving power supply that can be miniaturized and made light while satisfying given conditions required for a vehicle. <P>SOLUTION: According to the vehicle driving power supply 20, the electrostatic capacity of a capacitor 25 connected parallel to a fuel cell 21 is equal to or larger than 4 F and equal to or smaller than 30 F. The capacitor 25 has a larger weight-increase rate for its electrostatic capacity than the fuel cell 21 so that the use of the capacitor 25 of excessively large electrostatic capacity brings about the increase of the total weight of the vehicle. By setting the electrostatic capacity of the capacitor 25 to the range from 4 F to 30 F, upsizing that is caused by the excessive capacity increase of the capacitor 25 can be restrained. Thus, the miniaturization and light weight can be achieved while meeting the given conditions required for the vehicle. <P>COPYRIGHT: (C)2003,JPO |
