FUEL CELL SYSTEM AND CONTROL METHOD FOR FUEL CELL SYSTEM

During performance of low efficiency power generation, a control device controls the flow rate of feed of the oxidizing agent gas so that the amount of heat generation of the fuel cell accompanying power generation loss becomes a first amount of heat generation when the state of a mount on which the fuel cell system is mounted is a first mode and controls the flow rate of feed of the oxidizing agent gas so that the amount of heat generation becomes a second amount of heat generation smaller than the first amount of heat generation when the state of the mount is a second mode where the generated electric power of the fuel cell fluctuates more easily compared with the first mode.
