Brennstoffzellenfahrzeug

摘要

The invention provides a fuel cell vehicle capable of efficiently cooling a fuel stack and supplying sufficient reactant gas to the fuel stack with only a single air supply means. Two bypass valves 73, 74 are provided in the blowing passage 71, and a scavenge gas supply passage 72 for introducing external air into the inside of the fuel cell box 42 as scavenge gas is branched from the upstream bypass valve 73. The downstream bypass valve 74 contains an electromagnetic three-way valve, and the blowing passage 71 branches into a reactant gas supply passage 75 and a cooling gas supply passage 79 at the downstream bypass valve 74. The reactant gas supply passage 75 supplies external that is supplied from the blowing passage 71 to the fuel cell stack 48 as reactant gas (oxygen). The cooling gas pipe 79 supplies external air supplied from the blowing passage 71 to the fuel cell stack 48 as cooling gas.
