The present invention provides a fuel cell vehicle that can be used.

In order to solve the above problems, the invention described in claim 1, subframe (e.g., subframe 40 in the embodiment) fuel cell systems (e.g., the fuel cell stack 12 in the embodiment) are fixed to the floor When the panel (for example, the floor panel 1 in the embodiment) and the sub frame move differently in the vehicle width direction, the fuel cell system is configured to be slidable in the vehicle width direction together with the sub frame, and the fuel cell A reinforcing member (for example, the reinforcing member 57 in the embodiment) that slidably penetrates the system in the vehicle width direction is provided, and both ends of the reinforcing member are connected to the center console side wall (for example, the side wall 25 in the embodiment). When an impact force is applied from the side, the seat (for example, the front seat 20 in the embodiment) is used. The impact force is reached, characterized by being communicably configured via the reinforcing member from the collision side to the non-collision side.

  According to a second aspect of the present invention, the reinforcing member includes a rod (for example, the rod 61 in the embodiment) having engagement pieces (for example, the engagement pieces 56 in the embodiment) at both ends thereof, and the center console side wall. It is characterized by being engaged with a hook provided inside (for example, the hook 55 in the embodiment).

  According to a third aspect of the present invention, a fuel cell system is fixed to a subframe (for example, the subframe 40 in the embodiment), and a frame-like frame (for example, a frame body in the embodiment) surrounding the fuel cell system in the subframe. 66), and the frame-like frame is provided with a rod (for example, the rod 67 in the embodiment) provided with an engagement piece (for example, the engagement piece 69 in the embodiment) at a position corresponding to the left and right seats, When the engagement piece is engaged with a hook provided on the inner side wall of the center console and an impact force acts from the side of the vehicle, the impact force transmitted through the seat is transmitted via the frame-like frame. Thus, transmission from the collision side to the non-collision side is possible.

  According to the first aspect of the invention, by providing the reinforcing member, the impact force transmitted through the seat is reliably transmitted from the collision side to the non-collision side when the impact force acts from the side surface direction of the vehicle. Therefore, the impact on the fuel cell system can be reduced, and the impact force can be shared between the collision side and the non-collision side, so that the vehicle weight is not increased and the passenger space is narrowed. There is an effect that the safety of collision can be ensured without.

  According to the second aspect of the present invention, since the reinforcing member can be engaged with the center console with a simple structure, it can be realized without complicating the manufacturing process, and the reinforcing member can be stably supported with certainty. There is an effect that can.

  According to the invention described in claim 3, by providing the frame-shaped reinforcing member, when the impact force is applied from the side of the vehicle, the impact force transmitted through the seat is transferred from the collision side to the non-collision side. Since it can be transmitted reliably, the impact on the fuel cell system can be reduced, and the impact force can be shared between the collision side and the non-collision side, so the vehicle weight is not increased and the occupant There is an effect that it is possible to ensure collision safety without narrowing the space. In addition, since the structure of the fuel cell system is not affected, the fuel cell system can be realized without complicating the structure of the fuel cell system and without complicating the manufacturing process of the vehicle body.
