Abstract
An exhaust gas processing device for a fuel cell is disclosed. In the exhaust gas processing device, hydrogen gas purged from the fuel cell is mixed with cathode exhaust gas from the fuel cell and diluted prior to being discharged to an atmosphere. The exhaust gas processing device includes a reservoir in which purged hydrogen gas from the fuel cell is retained and mixed with cathode exhaust gas from the fuel cell, and an agitating gas introduction inlet provided at an upper part of the reservoir. The purged hydrogen gas is mixed with and diluted by agitating gas introduced from the agitating gas introduction inlet.

An exhaust gas processing device for a fuel cell, in which hydrogen gas purged from the fuel cell is mixed with cathode exhaust gas from the fuel cell and diluted prior to being discharged to an atmosphere, the exhaust gas processing device comprising:
- a reservoir in which purged hydrogen gas from the fuel cell is retained and mixed with cathode exhaust gas from the fuel cell;
- and
- an agitating gas introduction inlet provided at an upper part of the reservoir;
- wherein the purged hydrogen gas is mixed with and diluted by agitating gas introduced from the agitating gas introduction inlet.
An exhaust gas processing device for a fuel cell, in which hydrogen gas purged from the fuel cell is mixed with cathode exhaust gas from the fuel cell and diluted prior to being discharged to an atmosphere, the exhaust gas processing device comprising:
- a reservoir having an inlet through which purged hydrogen gas from the fuel cell is introduced into the reservoir and then mixed with cathode exhaust gas from the fuel cell;
- and
- an agitating gas introduction inlet provided at an upper part of the reservoir;
- wherein cathode exhaust gas to be supplied to the fuel cell is branched off and then supplied to the agitating gas introduction inlet.
An exhaust gas processing device for a fuel cell comprising:
- an exhaust fuel diluter having a reservoir in which hydrogen gas purged from the fuel cell is retained and then mixed with cathode exhaust gas from the fuel cell and diluted prior to being discharged to an atmosphere;
- an agitating gas pipe for introducing agitating gas which agitates the hydrogen gas retained in the reservoir;
- an adjustment valve for adjusting an amount of agitating gas;
- a hydrogen concentration detector for detecting a hydrogen concentration of emission gas discharged to the atmosphere;
- and
- a controller for adjusting the adjustment valve based on a detection signal from the hydrogen concentration detector.
An exhaust gas processing device for a fuel cell comprising:
- an exhaust fuel diluter having a reservoir in which hydrogen gas purged from the fuel cell is retained and then mixed with cathode exhaust gas from the fuel cell and diluted prior to being discharged to an atmosphere;
- an agitating gas pipe for introducing agitating gas which agitates the hydrogen gas retained in the reservoir;
- and
- an adjustment valve for adjusting an amount of agitating gas;
- wherein an introduction of agitating gas is controlled in response to an execution of purging from the fuel cell.
