The present invention provides a system for a fuel cell vehicle, capable of preventing an unnecessary error in calculating high potential avoidance power to calculate power for high potential avoidance with high accuracy. A fuel cell system 100 includes: a fuel cell 20 that receives the supply of reactant gas to generate power; a secondary battery 50 for storing part of the power generated by the fuel cell 20; calculation means 60 which, when surplus power for high potential avoidance is added to the output voltage of the fuel cell 20 to avoid a high potential, calculates high potential avoidance voltage to avoid the high potential by feedback control based on a deviation between power generation voltage of the fuel cell 20 and high potential avoidance target voltage; determination means 70 for determining whether the operating state of the fuel cell 20 corresponds to a prohibition condition A to prohibit updating of an integral term of the feedback control or a permission condition; and feedback control condition deciding means 80 for stopping the updating of the integral term when the operating state corresponds to the prohibition condition A or updating the integral term when the operating state corresponds to the permission condition.
