<P>PROBLEM TO BE SOLVED: To provide a technology of properly controlling a flow of fuel, for a fuel cell system equipped with a fuel cell and a combustion part. <P>SOLUTION: The fuel cell system is provided with a fuel cell, a fuel supply part supplying fuel to the fuel cell, a combustion part for combusting anode exhaust gas exhausted from an anode of the fuel cell, an oxygen concentration detecting part for detecting oxygen concentration in given gas, and a fuel flow control part for controlling a flow of fuel supplied from the fuel supply part to the fuel cell. The fuel flow control part controls the flow of fuel so that a swing amplitude of oxygen concentration in the fuel exhaust gas exhausted from the combustion part detected by the oxygen concentration detecting part lies between a first value and a second value larger than the first. <P>COPYRIGHT: (C)2010,JPO&INPIT |
