Therefore, the portable inverter device 35 can be loaded into the trunk room T / R and power can be supplied to an external AC device at an arbitrary place.

In this fuel cell vehicle 1, a hydrogen tank 9 having a spherical shape at its end is disposed between the left and right rear wheel houses 52, and the hydrogen tank 9 is located on the vehicle body front side from the bottom wall 51 of the trunk room T / R. A partition wall panel portion 13A of the rear floor panel 13 that protrudes upward is partitioned from the vehicle interior side, and a groove-shaped recess 41 that opens upward is provided between the raised portion of the partition wall panel portion 13A and one rear wheel house 52. Since the power contactor 34 is disposed in the concave portion 41, the dead space formed between the spherical end of the hydrogen tank 9 and the rear wheel house 52 is effectively used to connect the power contactor 34 to the vehicle. It can be arranged on the indoor side (above the rear floor panel 13).
Therefore, in this fuel cell vehicle 1, the power supply contactor 34 that handles high-voltage power and the hydrogen tank 9 that handles high-pressure gas can be reliably partitioned by the partition wall panel portion 13A of the rear floor panel 13, and the power supply contactor 34 has The inconvenience of pressing the space in the trunk room T / R and the cabin C can be eliminated.

Since it is arranged in a region overlapping in the longitudinal direction of the vehicle body, the periphery of the hydrogen tank 9 can be protected by the highly rigid rear subframe 12, and the front and rear of the power contactor 34 are also reliably protected by the same rear subframe 12. can do.

In the fuel cell vehicle 1, the power feeding connector 31 is disposed at a position separated from the rear side of the vehicle body of the power feeding contactor 34, and is connected to the power feeding contactor 34 by connection cables 44 a and 44 b. Therefore, even if a large load is input to the power supply connector 31 from the rear side of the vehicle body, the load from the power supply connector 31 toward the power supply contactor 34 can be transferred by the connection cables 44a and 44b. it can.
Therefore, in this fuel cell vehicle 1, the power contactor 34 can be more reliably protected against the impact load input from the rear of the vehicle body.

  Further, in this fuel cell vehicle 1, since the power feeding connector 31 is coupled to the bottom wall 40a of the recess 41 and the left and right side walls 52a, 40b via the bracket 43, the connector portion 38 of the inverter device 35 is provided. The power supply connector 31 on which a large load acts during insertion / extraction can be supported on the vehicle body side with high rigidity.

  Further, in the fuel cell vehicle 1 of this embodiment, the power supply contactor 34 is coupled to the upper portion of one rear side frame 61 via the rear floor panel 13, so that the rigidity of the support portion of the power supply contactor 34 is increased. The rear side frame 61 can reliably increase the height, and the one rear side frame 61 can also reliably protect the power feeding contactor 34 from external force.

By the way, although embodiment described above is the fuel cell vehicle 1 carrying the hydrogen tank 9, if it is an electric vehicle carrying a gas tank, it does not necessarily need to use a fuel cell.
However, in the above-described fuel cell vehicle 1 equipped with the fuel cell 2 using hydrogen gas as a fuel, a power supply contactor 34 that handles high-voltage power and a hydrogen tank 9 that handles hydrogen gas are separated by a partition panel portion 13A. Since it is reliably partitioned outside the passenger compartment, hydrogen gas can be reliably prevented from entering the passenger compartment.
