<p><P>PROBLEM TO BE SOLVED: To perform operation stop without exhausting an untreated carbon monoxide as it is, to prevent the reduction of the durability of a catalyst even if starting or stopping are repeated, to perform the operation stop without reducing the durability of a reforming part and to perform the operation stop without energy loss in an operation stopping method of a reforming device. <P>SOLUTION: In a controlling device of the reforming device, the purge of a remaining gas in the reforming device is started (time t0) by stopping the supply of a reforming fuel to a reforming part and also stopping the supply of the reforming water an evaporating part and by evaporating the reforming water remaining in the evaporating part by using the remaining heat of the reforming device, and an air for oxidation is circulated only a prescribed time T1 from the time of starting the purge. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
