PROBLEM TO BE SOLVED: To provide a fuel cell system capable of reducing a load on a battery and an auxiliary machine, while preventing a decrease in performance by regulating variation in electric power generation by a fuel cell, and capable of preventing deterioration in fuel economy of the vehicle.SOLUTION: A control part of a fuel cell system constituting a portion of a fuel cell system of a vehicle is configured to feedback road environments or the like to voltage control of a fuel cell. The control part determines whether or not it is an electric potential variation suppression mode of the fuel cell in accordance with the road environments affecting a travel state (step S34) after calculating a target voltage α of the fuel cell on the basis of an accelerator opening Wt of the vehicle (step S13). When the electric potential variation suppression mode is determined, the control part further determines the details of the road environments (step S35), and controls the fuel cell with a voltage value obtained by multiplying a regulation rate R corresponding to each of the road environments by the target voltage α. |
