- the fuel cells 20 may be arranged so as to fit in the space S.
- the configuration is adopted in which both the fuel cell 20 and the secondary battery 40 can be used as the drive sources of the wheels 11 and 12 (in terms of control, When the motors 11 and 12 are driven by both the fuel cell 20 and the secondary battery 40, the motors 11 and 12 are driven by only one of the fuel cell 20 and the secondary battery 40. It may include a configuration in which only one of the fuel cell 20 and the secondary battery 40 can be used as a drive source for the motors 11 and 12. Can be used as a drive source for the motors 11 and 12, and the other battery can be used as another device (for example, It may be configured so that it can be used as a power source for traps.
- a drive source for motors 11 and 12 may be provided in addition to the batteries 20 and 40, and one or both of the batteries 20 and 40 may serve to assist the drive source.
- the batteries 11 and 12 may be configured so that at least one of the fuel cell 20 and the secondary battery 40 can be used as a drive source.
- the left wheel motor 11 and the right wheel motor 12 are wheel wheels mounted on the left front wheel FLW and the right front wheel FRW.
- Motors for the left and right wheels 11 and 12 may be wheel-in motors attached to the left rear wheel and the right rear wheel.
- the fuel cell 20 can be arranged with a sufficient margin in this space.
- the present invention can be used in the automobile industry.
