- the fuel gas supply system such as the hydrogen tank ⁇ 70a, hydrogen supply pipe 1 7 1a, and regulator evening 1 72 is integrated into one place, the hydrogen supply pipe 1 71 can be shortened and hydrogen gas can be retained. Can also be suppressed.
- Such an advantage can be obtained by arranging the two fuel cell stacks 150 L b and 150 R b behind the rear panel 230, and thus the above-mentioned inclination is not an essential element.
- this tilt provides the advantages of space efficiency and reduced fluid stagnation in the manifolds (not shown) inside the two fuel cell stacks 150 b and 150 Rb. Is.
- two fuel cell stacks 150 and b, 150 Rb and secondary battery 700 are placed above the floor panel 2 1 0 a, so even if the chassis 1 0 is submerged.
- the submergence of the two fuel cell stacks 150 Lb, 150 Rb and the secondary battery 700 can be suppressed.
- FIG. 13 is an explanatory view showing the equipment arrangement of the fuel cell system in the first modification of the second embodiment.
- This first modification is the second modification in that a single fuel cell stack 150b is installed at the center in the vehicle width direction instead of the two fuel cell stacks 50Lb and 150Rb.
- the fluid distributor 14 O b is not used, and a fluid such as fuel gas or oxidant gas from the end (one or both) of the fuel cell stack 5 O b in the stacking direction. Will be supplied.
- the rearward arrangement of the rear panel 230 in the second embodiment is not limited to an equipment arrangement in which a plurality of fuel cell stacks are arranged on both of the fluid distributors 140 b. It can also be applied to the equipment of one fuel cell stack.
- FIGS. 14 and 15 are explanatory diagrams showing the equipment layout of the fuel cell system in the second modification of the second embodiment. It is.
- This second modified example is that the fuel cell stack 1 5 0 c is installed along the inclination of the rear panel 2 30 at the rear of the rear panel 2 30. (Including the first variation)
- the second embodiment is that the stacking direction of a single fuel cell stack 1 5 0 c is closer to the vertical direction than the left and right direction of the chassis 10. Is different.
- the cooling water supply port 1 4 1 in, the cooling water discharge port 1 4 1 0 ut, the oxidant gas supply port 1 4 2 in, the power sword off gas discharge port 1 4 2 0 ut, hydrogen gas supply port 1 4 3 in, and vandalized fugas 1 4 3 out are intensively arranged at the bottom stack end of the fuel cell stack 1 5 0 c.
- the high voltage component 1 2 9 c is arranged at the upper stacking end of the fuel cell stack 1 5 0 c. Therefore, even if the chassis 10 is submerged, the high voltage component 1 2 9 c is submerged. This is similar to the first embodiment in that it has the advantage that it can be avoided.
- the number of stacked fuel cell stacks 1 5 0 c is further increased and decreased to maintain the output capacity of the fuel cell stack 1 5 0 c while maintaining the output capacity of the fuel cell stack 1 5 0 c. Since it is possible to adjust the thickness W s, there is an advantage that the design of the fuel cell stack 15 50 c corresponding to the space behind the rear panel 2 30 can be easily made using this design freedom. Furthermore, since a large space in the vertical direction is obtained behind the rear panel 230, it is possible to reduce the thickness W s and increase the size of the cabin.
- the fuel cell stack 150 is stacked in a direction closer to the vertical direction than the front-rear direction and the vehicle width direction of the chassis 10, so the fuel cell stack 15 5 c is stacked inside the fuel cell stack 15 50 c. Since the manifold (not shown) formed in the direction does not become horizontal regardless of the inclination of the vehicle, there is an advantage that the generated water is difficult to stay. In addition, since the power sword off-gas outlet 1 4 2 0 ut is equipped at the lower end of the fuel cell stack 1 5 0 c, the generated water generated on the power sword pole side (not shown) There is also an advantage that it can be smoothly discharged at the lower end of the fuel cell stack.
- FIG. 16 is an explanatory view showing the equipment arrangement of the fuel cell system in a third modification of the second embodiment.
- This third variation is equipped with a stacking direction of the fuel cell stack 15 50 d closer to the vertical direction than the horizontal direction of the chassis 10 at the rear of the rear panel 2 30. It is the same as the second variation in that it is equipped with an inclination along the inclination of 2 3 0, but the secondary battery 7 0 0 a is equipped on the right side of the fuel cell stack 1 5 0 d. This is different from the second modification.
- the fuel cell stack 150 e and the secondary battery 70 a may be symmetrically arranged on the left and right sides so that the left and right weight balance is equal.
- the hydrogen tank can be placed under the rear seat.
- the secondary battery 70 0 a may be a capacitor or other power storage device, and this is the same for the other secondary batteries 16 0 and 70 0.
