| Zusammenfassung: | The invention discloses a hydrogen fuel cell waste gas utilization system which comprises a hydrogen supply subsystem, a fuel cell stack, a fuel cell water/heat management subsystem, a filter, an air compressor, an air humidification device and a steam-water separation device, the device is characterized in that waste gas discharged by the steam-water separation device is directly introduced into an inlet of the air compressor driving motor cooling flow channel or is introduced into an inlet of the air compressor driving motor cooling flow channel after being cooled, air cooling is conducted on the air compressor driving motor, and finally the waste gas is discharged through an outlet of the air compressor driving motor cooling flow channel. A waste gas utilization flow channel for guiding the stack waste gas subjected to steam-water separation to the inlet of the air compressor driving motor cooling flow channel is arranged between the steam-water separation device and the inlet of the air compressor driving |
