ABSTRACT:
A fuel cell system includes: a fuel cell; a fuel generator for generating a fuel gas from a feedstock; a fuel supplying conduit for supplying the fuel gas produced by the fuel generator to the fuel cell; a fuel exhausting conduit for introducing a remaining fuel gas, which has not been consumed by the fuel cell, to a combustion chamber of the fuel generator; a first bypass conduit for connecting the fuel supplying conduit with the fuel exhausting conduit; a second bypass conduit for supplying the feedstock to the fuel exhausting conduit. The fuel cell system further comprises: either one of (1) a gas pathway switching device A installed at a junction of the fuel supplying conduit and the first bypass conduit; and (2) a gas pathway switching device B installed at a junction of the fuel exhausting conduit and the first bypass conduit. The second bypass conduit is connected to the fuel exhausting conduit at an upper stream side of the flow of the remaining fuel gas than the junction with the first bypass conduit.
