    摘要： A fuel cell system including: a fuel cell; a fuel processor including a reformer and a selective oxidizer configured to cause a reaction between carbon monoxide contained in a reformed gas and oxygen in air, an air blower configured to send air for use in power generation to a cathode of the fuel cell and to send air for use in a selective oxidation reaction to the selective oxidizer; a cathode air passage, one end of which is connected to the cathode of the fuel cell and the other end of which is connected to the air blower; a selective oxidation air passage, one end of which is connected to a branching point, on the cathode air passage, at which the selective oxidation air passage branches off from the cathode air passage, and the other end of which is connected to the selective oxidizer; a selective oxidation air meter configured to measure the flow rate of air supplied to the selective oxidizer; and a controller configured to control the air blower. The cathode air passage and the selective oxidation air passage are formed such that the flow rate of the air sent to the selective oxidizer is less than the flow rate of the air sent to the cathode. While the fuel cell is generating power, the controller performs feedback control of controlling the supply performance of the air blower based on the air flow rate measured by the selective oxidation air meter, such that the flow rate of the air sent to the selective oxidizer becomes a target value.
