Embodiment approach

[0020] figure 1 It is a schematic side view showing the vehicle 10 in this embodiment. figure 1 Arrows indicating the X direction, the Y direction, and the Z direction that are perpendicular to each other are shown in the figure. The X direction corresponds to the width direction of the vehicle 10 , the Y direction corresponds to the front-rear direction of the vehicle 10 , and the Z direction corresponds to the height direction of the vehicle 10 . Arrows representing the X direction, the Y direction, and the Z direction are also referred to later in each figure with figure 1 The corresponding means are illustrated.

[0021] The vehicle 10 is a fuel cell vehicle including a fuel cell as a power source. In the present embodiment, a vehicle 10 includes a plurality of fuel cell units 100 . In this specification, a "fuel cell unit" refers to a unit composed of a fuel cell and a device integrated with a fuel cell body. The "device integrally connected to the fuel cell body" in...

Embodiment approach 1

[0059] In the support frame 20 included in the fuel cell assembly 200 of the above-mentioned embodiment, the first frame part 21 and the second frame part 22 may also be composed of plate-shaped members arranged in two layers above and below instead of linear ones. Frame members 31 to 34 constitute. In addition, the first fixing portion for fixing the first fuel cell unit 101 may be formed of one or a plurality of plate members stretched between the first frame members 31 instead of a plurality of second frame members 32 . The second fixing portion for fixing the second fuel cell unit 102 may be formed of one or a plurality of plate-shaped members stretched between the third frame members 33 instead of a plurality of fourth frame members 34 .

Embodiment approach 2

[0061] In the fuel cell assembly 200 of the above-described embodiment, the first fuel cell unit 101 and the second fuel cell unit 102 may not be disposed at positions deviated in the front-rear direction of the vehicle 10 . In addition, the first fuel cell unit 101 and the second fuel cell unit 102 may be arranged in a state where they do not overlap with each other when viewed in the height direction of the vehicle 10 .

Abstract

The invention relates to a fuel cell assembly and a vehicle including the same. A fuel cell assembly is mounted on a vehicle via a mounting portion. The fuel cell assembly includes a first fuel cell unit, a first frame portion on which the first fuel cell unit is mounted and fixed, a second fuel cell unit, a second frame portion on which the second fuel cell unit is mounted and fixed, and a connecting portion that connects the first frame portion and the second frame portion such that the second fuel cell unit is located above the first fuel cell unit.

Description

technical field [0001] The present disclosure relates to a fuel cell assembly and a vehicle including the fuel cell assembly. Background technique [0002] There are cases where a plurality of fuel cell units are mounted on a fuel cell vehicle. For example, the following Japanese Patent No. 4686362 discloses a fuel cell vehicle in which two fuel cell stacks corresponding to fuel cell units are arranged in a line in the width direction of the vehicle. [0003] In a fuel cell vehicle, the fuel cell unit is usually fixed to the frame of the fuel cell vehicle via a mount portion including an elastic buffer member that elastically deforms to absorb vibration and impact transmitted from the vehicle body. In this case, the fuel cell may be displaced due to elastic deformation of the elastic buffer member in the mounting portion. Therefore, in a fuel cell vehicle, in order to suppress interference between the fuel cell unit and surrounding structures, it is preferable to provide a...
