CARBON MONOXIDE TREATMENT APPARATUS

摘要

PROBLEM TO BE SOLVED: To make a stable carbon monoxide treatment capability exhibited even in the case where the use conditions are changed by forming a catalytic reaction part having a catalyst layer containing a platinum-group metal catalyst, a raw material gas supply part for supplying hydrogen containing carbon monoxide an auxiliary component, and a branched part joined to the catalytic reaction part. SOLUTION: A raw material gas generated in a raw material gas supply part 1 is supplied to a catalytic reaction part 3 through a raw material gas supply route 5. At that time, air from the oxidizing gas supply part 2 is supplied to the raw material gas through a joint 6. A part of the raw material gas is led to the upstream side of the catalyst body 3a in the catalytic reaction part 3 and the remaining is led to the downstream side of the catalyst body 3a through a branched route 8. The amounts of the raw material gas to led to the raw material gas supply route 5 and to the branched route 8 are controlled by a branching amount control part 7. The mixed gas is further led to another catalyst body 3b to remove carbon monoxide in the raw material gas by oxidation. After that, the raw material gas is supplied to a fuel cell main body from a raw material gas discharge route 9.
