Abstract:
1. An exhaust gas processing device for a fuel cell, in which hydrogen gas intermittently 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 the cathode exhaust gas from the fuel cell; 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; and an exhaust gas pipe adapted to carry the cathode exhaust gas discharged from the fuel cell, wherein said exhaust gas pipe extends through a lower part of the reservoir and includes at least one hole positioned within the reservoir; wherein a pressure of the cathode exhaust gas flowing through the exhaust gas pipe is lower at the reservoir than a pressure in the reservoir.
