Vehicle structure of fuel cell vehicle

1. A vehicle structure of a fuel cell vehicle, comprising:

hydrogen tanks that are disposed at a roof side and an underfloor side of a vehicle cabin, and that are filled with hydrogen;

a set of cases that house the hydrogen tanks at the roof side and the underfloor side respectively, and that respectively have, in a vehicle longitudinal direction, mouthpieces of a connecting pipe that is connected to the hydrogen tanks;

a center module in which the set of cases is provided;

a front module that is joined to a vehicle front side of the center module;

a rear module that is joined to a vehicle rear side of the center module;

a fuel cell stack that is provided at the front module or the rear module, and to which the hydrogen is supplied from a pipe connected to the mouthpieces;

a control unit that is provided at the front module or the rear module, and that controls outputted electric power of the fuel cell stack; and

a driving unit that is provided at the front module or the rear module, and that drives driving wheels by outputted electric power of the control unit.

2. The vehicle structure of a fuel cell vehicle of claim 1 , wherein positions, in the vehicle longitudinal direction, of extended portions, which extend in a vehicle vertical direction, of the pipes are within a range between a front end and a rear end of a wheel.

3. The vehicle structure of a fuel cell vehicle of claim 1 , wherein:

high-voltage parts including the fuel cell stack, the control unit and the driving unit are provided at one of the from module or the rear module, and

the vehicle structure further comprises an autonomous driving unit that controls autonomous driving of the vehicle, at another of the front module or the rear module.

4. The vehicle structure of a fuel cell vehicle of claim 1 , wherein:

the hydrogen tanks are shaped as tubes whose lengths run in a vehicle transverse direction, and

a plurality of the hydrogen tanks are disposed along the vehicle longitudinal direction at interiors of the cases.

5. The vehicle structure of a fuel cell vehicle of claim 1 , wherein:

the fuel cell stack, the control unit and the driving unit are disposed at one of the front module or the rear module, and

an end portion entrance/exit through which passengers can enter and exit is disposed at a wall portion of another of the front module or the rear module.

6. The vehicle structure of a fuel cell vehicle of claim 1 , further comprising a filling port that is disposed at a same side as the fuel cell stack in the vehicle longitudinal direction, and that is for filling hydrogen.
