Abstract
In a fuel cell system which includes a fuel cell converter and a battery converter, noise generated in a high load region in particular is effectively inhibited, and silence is improved. A fuel cell system includes a fuel cell converter provided between a fuel cell and a load device, and a battery converter provided between a battery and the load device. The fuel cell system includes frequency setting means for setting a driving frequency band of the fuel cell converter and a driving frequency band of the battery converter so that these driving frequency bands do not overlap when a load of the load device is more than a predetermined threshold.
