  • Patent number: 11845333
    Abstract: A container holding mechanism is applied to a fuel cell vehicle including a driving mechanism capable of driving rear wheels and disposed on a side of the rear wheels. The container holding mechanism includes a first hydrogen gas, a second hydrogen gas, a third hydrogen gas container, and a moving unit. The first hydrogen gas container is disposed behind a rear drive shaft. The second hydrogen gas container is disposed in front of the rear drive shaft. The third hydrogen gas container disposed in parallel with the second hydrogen gas container in front of the rear drive shaft. The moving unit is configured to move the driving mechanism pushed out by the first hydrogen gas container in collision in such a manner that the driving mechanism avoids the second hydrogen gas container and the third hydrogen gas container.
