Abstract: The present invention provides an arrangement structure of component parts for a fuel cell vehicle that efficiently arranges various component parts of a fuel cell system, a hydrogen supply system and an electric driving system to make the best use of interior space, improve weight distribution of the vehicle, reduce noise, and provide security against a rear-end collision. The arrangement structure of the present invention includes an engine room, in which a motor 11 and an air blower 12 are mounted on an upper portion of a frame 10, and component parts of an electrical system and a fuel cell system are arranged on an upper portion of the motor 11; an under-floor 20, on which a humidifier 21, a stack 22, a fuel processing system (FPS) box 23, and a hydrogen tank 40 are mounted; seats 29, beneath which electronic parts are arranged on the under-floor 20; and a trunk room, in which a super-capacitor and an initial charging device are mounted.

Abstract: The present invention provides an engine room frame structure of a fuel cell vehicle that improves assembly process by a module operation and reduces the number of assembly processes, thus improving productivity. The engine room frame structure of a fuel cell vehicle includes: a sub-frame on which a motor 11, an air blower 12, and component parts 13 of an electrical system and a fuel cell system are mounted in the form of a module; and a main frame 20 on which the sub-frame 10 is mounted.
