In a fuel cell vehicle 10 of the invention, fuel cells 20 are integrally placed in a lower space 15 of a front seat 14, while a secondary battery 40 is integrally placed in a lower space 18 of a rear seat 17. The integral arrangements of the fuel cells 20 and the secondary battery 40 separately in the lower space 15 of the front seat 14 and in the lower space 18 of the rear seat 17 ensure high-performance operations of both the fuel cells 20 and the secondary battery 40 having different working environments. This arrangement also attains the effective use of the generally-dead, lower spaces 15 and 18 of the front and rear seats 14 and 17 to receive the fuel cells 20, the secondary battery 40, and their peripheral equipment.
