Embodiment approach 1

[0066] Embodiment 1 of the present invention relates to a fuel cell vehicle in which a related device, that is, a DC-DC converter, is arranged at a position closer to the front surface of the vehicle (one aspect of the outer surface) than the fuel cell unit. Hereinafter, the configuration of the fuel cell unit will be described first, and then the details of each component device will be described.

[0067] (System Components)

[0068] figure 1 It is a configuration diagram of a fuel cell system to which the present invention is applied.

[0069] figure 1 The fuel cell system 10 in this has the following configurations: a fuel gas supply system 4; an oxidizing gas supply system 7; a coolant supply system 3; and an electric power system 9. The fuel gas supply system 4 is a system for supplying fuel gas (hydrogen gas) to the fuel cell 20. The oxidizing gas supply system 7 is a system for supplying oxidizing gas (air) to the fuel cell 20. The cooling liquid supply system 3 is a syste...

Embodiment approach 2

[0147] The second embodiment of the present invention relates to an example in which the FC converter 90 as a related device is arranged on an inclined surface.

[0148] In the first embodiment described above, the FC converter 90 is arranged on the vehicle front side of the fuel cell unit 201, and the inclined portion 256 is provided on the vehicle front side of the FC converter 90. The second embodiment is the same as the first embodiment described above in that the FC converter 90 is arranged on the front side of the vehicle of the fuel cell unit 201, but is different in that the FC converter 90 is arranged on the inclined surface.

[0149] In the second embodiment, the fuel cell system 10 (refer to figure 1 ), the structure of the vehicle 100 (see figure 2 as well as image 3 ) Same as the above-mentioned first embodiment. Therefore, the same reference numerals as in the first embodiment described above are assigned, and the description thereof is omitted.

Embodiment approach 3

[0159] The third embodiment relates to a modification of the form of the fuel cell unit.

[0160] in Picture 10 In the figure, a plan view of a vehicle explaining the arrangement of the fuel cell system in the third embodiment is shown. Such as Picture 10 As shown, the fuel cell unit 201b in the third embodiment has a shape that branches downward in two strands in a plan view. The fuel cell 20 housed in the fuel cell unit 201b is separated into a first fuel cell stack 20-1 and a second fuel cell stack 20-2, and is housed in each branch-shaped case of the fuel cell unit 201b. The pipes 291 are connected so as to be able to supply oxidizing gas, fuel gas, and coolant to the first fuel cell stack 20-1 and the second fuel cell stack 20-2. Fuel cell unit 201b, such as Picture 10 As shown, for example, the openings 293 branched into two strands are provided at the lower parts of the front seats 103L and 103R so that they face the front of the vehicle.

[0161] The FC converter 90 is...

Abstract

The present invention provides a mounting structure of a fuel cell system capable of suppressing an increase in vehicle weight and suppressing a collision between an associated device and a fuel cell. A fuel cell system mounted on a vehicle (100) includes: a fuel cell unit containing a fuel cell (20); and an associated device (90) electrically connected to the fuel cell (20) and connected to the fuel cell unit. Neighborhood settings. The associated device (90) is arranged closer to the outer surface of the vehicle than the fuel cell unit.

Description

Technical field [0001] The present invention relates to a vehicle equipped with a fuel cell system, and more particularly to a structure for mounting fuel cell related devices such as a fuel cell and a DC / DC converter (converter). Background technique [0002] Development of a vehicle (hereinafter also referred to as a "fuel cell vehicle") that is configured to be driven by a motor for driving the vehicle by supplying electricity from a fuel cell system. In a fuel cell vehicle, the components of the fuel cell system are arranged under the floor in the center of the vehicle to ensure safety during a collision. [0003] For example, International Publication No. 2003-104010 discloses a fuel cell vehicle (Patent Document 1). The fuel cell vehicle is equipped with a fuel cell in the area below the front seat (frontseat). ) A part of the auxiliary equipment of the fuel cell is housed inside. [0004] Japanese Patent Application Laid-Open No. 2007-15616 discloses a fuel cell vehicle (Pat...
