<P>PROBLEM TO BE SOLVED: To appropriately treat hydrogen offgas without releasing it into the atmosphere as it is and without adding any new special treatment device, by making a fuel cell body absorb the hydrogen offgas purged from the body together with the air. <P>SOLUTION: The hydrogen offgas treatment system is provided with: a fuel cell body 13 generating power with reaction of hydrogen and oxygen in the air; an air suction line 14 supplying air to the fuel cell body 13; a hydrogen supply line 15 supplying hydrogen to the fuel cell body 13; an exhaust line 16 draining exhaust air from the fuel cell body 13; and a hydrogen purge line 17 for draining hydrogen offgas purged when the hydrogen gas inside the fuel cell body 13 is purged. The hydrogen purge line 17 is connected to a middle part of the air suction line 14, and the hydrogen offgas purged from the fuel cell body 13 is made suctioned by the fuel cell body 13 through the air suction line 14 together with air. <P>COPYRIGHT: (C)2011,JPO&INPIT |
