Vehicle with fuel cell mounted therein

摘要

A vehicle includes a fuel cell having a cell stack and an end plate provided to receive pressing force, the end plate having such a strength as to resist the pressing force; and a vehicle-side stack frame on which the fuel cell is mounted in a vehicle underfloor region in such a mounting posture that fuel-cell unit cells are stacked horizontally. The vehicle-side stack frame is built over a range from an end plate side to the other end side of the cell stack in the stacking direction of the fuel-cell unit cells in an occupation area occupied by the fuel cell in the mounting posture in the vehicle underfloor region. In a region where it is assumed that external force can reach the occupation area in the vicinity of the end plate, the vehicle-side stack frame has a shortest distance to the end plate that is smaller than a shortest distance to any other members in the vicinity of the end plate.

1. A vehicle comprising:
a fuel cell having a cell stack in which a plurality of fuel-cell unit cells are stacked in layers, and an end plate provided at one end portion of the cell stack to receive pressing force that is a force fixing the cell stack in a direction of the stacking of the fuel-cell unit cells, the end plate having such a strength as to resist the pressing force; and a vehicle-side stack frame on which the fuel cell is mounted in a vehicle underfloor region in such a mounting posture that the fuel-cell unit cells are stacked horizontally, wherein the vehicle-side stack frame is built over a range from an end plate side to the other end side of the cell stack along the stacking direction of the fuel-cell unit cells, wherein the fuel cell is housed in a fuel cell casing including a lower cover, and is fixed to the vehicle-side stack frame while the fuel cell is maintained above the vehicle-side stack frame, and wherein a shortest distance from the vehicle-side stack frame to a lower end of the end plate is smaller than a shortest distance from the vehicle-side stack frame to a lower end of an auxiliary machinery equipped on the fuel cell.
