<P>PROBLEM TO BE SOLVED: To provide a treatment device of exhaust hydrogen that discharges hydrogen to the atmosphere at the concentration of inflammable range or less with a simple structure without using a diluting chamber. <P>SOLUTION: When a control valve 50 is put in communicating state, the exhaust hydrogen gas on the fuel pole side 13 is introduced into the housing chamber 21 through an exhaust hydrogen gas inlet port 23. Then, the pressure in the first space of the housing chamber 21 increases temporarily. However, by a flow regulating part 31 of the partition wall 30, back flow of the exhaust hydrogen gas introduced into the housing chamber 21 to an exhaust air supply tube 45 is prevented. When the control valve 50 is put in a non-communicating state, the exhaust air introduced from an exhaust air inlet port 24 passes through the flow regulating part 31 of the partition wall 30 and moves the exhaust hydrogen gas to a discharge part 21b in order. Then, the exhaust hydrogen gas is discharged to the vicinity of the air open end of an air exhaust tube 41 from the discharge part 21b through an exhaust hydrogen gas exhaust tube 46, and after being diluted by the exhaust air flowing in the air exhaust tube 41, is discharged to the atmosphere. <P>COPYRIGHT: (C)2004,JPO |
