Further, the front cover plate 321 forms a third side plate.

  The hydrogen cylinder unit 3 includes a plurality (four in FIG. 3) of hydrogen cylinders 33, 33,. The hydrogen cylinder 33 is, for example, an MH (Metal Hydride) cylinder using a hydrogen storage alloy. As shown in FIGS. 3 and 5, the hydrogen cylinder 33 has a bottomed cylindrical shape, one end has a tapered shape, and a valve 33 a is attached thereto. The hydrogen cylinder 33 is arranged so that the valve 33 a is positioned on the front side, and the other end is in contact with the rear side plate 311 of the container unit 31. Note that the other end of the hydrogen cylinder 33 may be disposed so as to face the rear plate 311 with a slight gap. Further, the hydrogen cylinders 33 are accommodated in the opposing direction of the left side plate 312 and the right side plate 313 of the container part 31. Adjacent hydrogen cylinders 33 are in contact with each other. Further, the hydrogen cylinders 33, 33,... Are sandwiched between the left side plate 312 and the right side plate 313 of the container part 31. A spacer may be provided between the hydrogen cylinders 33.

  The container portion 31 is provided with a first inner wall 34 so as to face the rear side plate 311. The first inner wall 34 has a plate shape extending in the left-right direction. The rear surface of the first inner wall 34 is in contact with the end surface of the valve 33a, and each hydrogen cylinder 33 is sandwiched in the length direction by the first inner wall 34 and the rear plate 311 of the container portion 31 together with the valve 33a.

  As shown in FIG. 4, the container portion 31 is provided with a second inner wall 35 between the first inner wall 34 and the front cover plate 321 of the cover portion 32. The second inner wall 35 has a plate shape extending in the left-right direction. As shown in FIG. 4, the second inner wall 35 faces the front cover plate 321 of the cover portion 32 with a predetermined distance X therebetween. The first inner wall 34 and the second inner wall 35 are connected by three beam members 36, 36, 36 arranged side by side in the left-right direction. The three beam members 36, 36, 36 are arranged between the right end portions of the first inner wall 34 and the second inner wall 35, between the two hydrogen cylinders 33, 33 on the right side, and between the two hydrogen cylinders 33, 33 on the left side. Yes.

  The beam member 36 is a plate-like member having a U-shaped cross section as shown in FIG. The beam member 36 is arranged so that the U-shaped opening side is located on the rear side. The beam member 36 has a U-shaped opening side portion fixed to the first inner wall 34, and an opposite side portion of the opening side portion is fixed to the second inner wall 35, thereby connecting the first inner wall 34 and the second inner wall 35. To do.

  The number of beam members is not limited to three, but may be two or less or four or more. Further, the beam member 36 may have any structure as long as the first inner wall 34 and the second inner wall 35 are connected to each other and can keep the distance when subjected to an impact. For example, the beam member 36 may be formed of a pair of two plates facing each other and disposed between the first inner wall 34 and the second inner wall 35 so as to connect the first inner wall 34 and the second inner wall 35. . The beam member 36 may be cylindrical.

  In the housing 30, a pipe 37 through which hydrogen passes is disposed between the first inner wall 34 and the second inner wall 35. The pipe 37 includes four valve connecting portions 370, 370,... And a flow path 371 connected to each valve connecting portion 370. As shown in FIG. 3, each valve connecting portion 370 is connected to each of the valves 33 a of the hydrogen cylinder 33 and protrudes forward from the first inner wall 34. The flow path 371 extends in the left-right direction, and is folded back on the U shape on the right side plate 313 side in the housing 30 as indicated by a broken line in FIG. 6. As shown in FIG. 3, on the left side plate 312 side in the housing 30, the flow path 371 has one end portion connected to the leftmost valve connecting portion 370 and the other end portion connected to the left side plate of the container portion 31. It is connected to a hydrogen delivery port 373 protruding from the housing 312 to the outside of the housing 30. The hydrogen delivery port 373 is connected to the supply pipeline 4 when the hydrogen cylinder unit 3 is assembled to a fuel cell.

  In the left side plate 312, a recessed portion 314 that is recessed inside the housing 30 is formed at a portion where the hydrogen delivery port 373 is provided, and the hydrogen delivery port 373 is located in the recessed portion 314. Thereby, even if the hydrogen cylinder unit 3 falls or falls from the left side plate 312 side, it is possible to prevent a force from being applied to the hydrogen delivery port 373 and to prevent the piping 37 from being damaged.

  The hydrogen in the hydrogen cylinder 33 passes through the flow path 371 after passing through the valve connecting portion 370 by opening the valve 33a. The hydrogen that has passed through the flow path 371 is sent out from the hydrogen outlet 373. Hydrogen delivered from the hydrogen delivery port 373 is supplied to the power generation unit 1 through the supply pipeline 4.

  According to the above configuration, since the movement of the hydrogen cylinder 33 in the length direction is restricted by the first inner wall 34, the pipe 37 can be prevented from being damaged. In addition, since there is no gap between the adjacent hydrogen cylinders 33, the hydrogen cylinder 33 is difficult to move when an impact is applied to the housing 30. Further, since the hydrogen cylinders 33, 33,... Are held between the left side plate 312 and the right side plate 313, each hydrogen cylinder 33 faces the left side plate 312 and the right side plate 313 when an impact is applied to the housing 30. It is difficult to move in the direction. Further, since each hydrogen cylinder 33 is sandwiched between the first inner wall 34 and the rear side plate 311, the hydrogen cylinder 33 is difficult to move in the length direction when an impact is applied to the housing 30. Thereby, damage to piping 37 can be prevented more effectively.

  Even when the hydrogen cylinder unit 3 falls or falls from the second inner wall 35 side, the force received by the second inner wall 35 is distributed to the beam members 36, 36, 36. Since the dispersed force is transmitted to the first inner wall 34 and the valve 33a and not to the pipe 37, the pipe 37 can be prevented from being damaged.

  Further, since the front cover plate 321 and the second inner wall 35 are separated from each other by a predetermined distance X, a space is formed. Therefore, even when an impact is received from the front cover plate 321 side, the space is added to the second inner wall 35. Impact, deformation, etc. can be reduced. Thereby, damage to piping 37 can be prevented more effectively.
