FUEL CELL VEHICLE WITH SINGLE AIR SUPPLY

摘要

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