Provided is a vehicle with a fuel cell unit, specifically, a vehicle with a configuration in which a fuel cell unit is arranged anterior to a dashboard as well as a toe board located below the dashboard, where the fuel cell unit is arranged to be prevented from colliding with the toe board upon occurrence of unforeseen impact on the fuel cell unit. The fuel cell unit includes at least a fuel cell group, a stack manifold provided on the fuel cell group on the vehicle rear side, and an air valve device fixed to the stack manifold. The stack manifold has a recess portion formed in a part thereof. The air valve device is fixed to the stack manifold with at least a part of the air valve device received within the recess portion.

A fuel cell vehicle includes a fuel cell stack, a stack case containing the fuel cell stack, and an interruption control unit for electrically interrupting an output line of the fuel cell stack at the time of vehicle collision. The interruption control unit is arranged on an upper surface of the stack case, and a front end of the interruption control unit is positioned on the vehicle rear side as compared with a front end of the stack case.

A support frame includes a first member, a second member, and a third member each having a surface. The first member is connected to the second member by fitting, and the first member is connected to the third member by fitting. In each of connecting portions, one of members connected to each other is defined as a first connecting member and the other one of the members is defined as a second connecting member. A side end portion of the first connecting member on a side facing the second connecting member is provided with an extending portion. The extending portion has a flat shape, and the extending portion is provided with a fitted portion constituted by a recessed portion. A side end portion of the second connecting member on a side facing the first connecting member is provided with a fitting portion configured to fit in the fitted portion.

A vehicle includes: a front room disposed at a front part of the vehicle in a longitudinal direction of the vehicle; a fuel cell stack disposed in the front room, the fuel cell stack including multiple cells stacked in the longitudinal direction; a bumper reinforcement disposed at a front part of the front room in the longitudinal direction; and a buffer member disposed between the fuel cell stack and the bumper reinforcement in the longitudinal direction. At least a part of the buffer member overlaps with the bumper reinforcement, as viewed from a direction along the longitudinal direction.
