摘要： In a fuel cell system, when an electric current drawn from fuel cells is controlled based on a target power generation value, an upper limit of the electric current is optimally set to make suspensions of operation caused by voltage drops to be as infrequent as possible. The upper limit of the electric current is set by adding a predetermined offset value (e.g., 2 A) to an average value of the electric current before a predetermined delay time (e.g., 10 seconds). Moreover, when the electric current drawn from the fuel cells is controlled based on a target power generation value, the value of the electric current is compared with the upper limit of the electric current, to control the electric current.
