Abstract
A fuel cell system configured to generate an electric power by supplying an anode gas and a cathode gas to a fuel cell includes: a connection line configured to connect the fuel cell to an electric load; a converter connected to the connection line and a battery, the converter being configured to adjust a voltage of the connection line; a target output current calculating unit configured to calculate a target output current of the fuel cell in accordance with a load of the electric load; a converter control unit configured to carry out a switching control for the converter in accordance with the target output current; and a flow rate control unit configured to control a flow rate of the cathode gas to be supplied to the fuel cell in accordance with the target output current. The target output current calculating unit sets up an upper limit to the target output current on the basis of a generated electric power of the fuel cell and a guaranteed minimum voltage of the connection line for ensuring performance of the fuel cell and the electric load.
