Abstract:
1. A method for operating a fuel cell system, comprising: removing, by a deodorizing device, an odor component contained in a raw material gas; generating, by a reformer, a hydrogen-containing gas through a reforming reaction using the raw material gas that has passed through the deodorizing device; generating power, by a fuel cell, using the hydrogen-containing gas that is discharged from the reformer; performing a stuck-state check on at least one on-off valve provided on a combustible gas passage which is downstream from the deodorizing device and which extends through the reformer, by supplying the raw material gas to the combustible gas passage; ventilating the inside of a casing when performing the stuck-state check, the casing accommodating at least the deodorizing device, the fuel cell, the reformer and the combustible gas passage; and prohibiting a pressure compensation operation, which is an operation to supply the raw material gas into the reformer in association with a temperature decrease in the reformer, from being performed on the reformer if an abnormality is detected in at least one of the stuck-state check and a leak check performed on the combustible gas passage after the stuck-state check is performed.
