The present invention provides a fuel cell-equipped vehicle which is capable of effectively discharging a reaction gas leaking from a stacked cell body outside of a vehicle. A fuel cell-equipped vehicle comprises: a fuel cell stack disposed in a front space of a vehicle body separated by a partition member and configured to accommodate a stacked cell body, in which a plurality of fuel cells are stacked, in a casing; and an air conditioner disposed in a rear space of the vehicle body separated by the partition member, wherein external air is introduced into the air conditioner through an external air intake port formed at a portion of the partition member located on a first side with respect to a center in a vehicle width direction of the vehicle body, an upstream end of an exhaust duct configured to discharge a reaction gas in the casing is connected to a communication port formed in the casing to allow communication between an inside and outside of the fuel cell stack, and a downstream end of the exhaust duct communicates with an outside of the vehicle body at a portion located on a second side with respect to the center in the vehicle width direction.
Description
technical field [0001] The present invention relates to a vehicle equipped with a fuel cell. Background technique [0002] In a fuel cell-equipped vehicle, a drive motor and a fuel cell stack are accommodated in a motor compartment (a front space) at the front of the vehicle body. [0003] The motor room is partitioned by a partition member (for example, a dash panel, a cover member, etc.). A fuel cell stack has a cell stack formed by stacking a plurality of unit cells, and a case that accommodates the cell stack. [0004] A fuel cell-equipped vehicle travels by driving a driving motor with electric energy generated by a fuel cell stack. [0005] However, in the fuel cell stack described above, the reactive gas (fuel gas, oxidant gas) flowing in the cell stack sometimes leaks into the motor chamber through gaps between the unit cells or the like. [0006] Therefore, for example, Japanese Patent Application Laid-Open No. 2004-40950 discloses a structure in which a ventilat...
