To suppress the freezing of a pressure sensor in a fuel cell system.SOLUTION: A control device for fuel cell vehicles in which a fuel cell stack is mounted comprises: a gas temperature acquisition unit that acquires a detected gas temperature from a temperature sensor which is located in a fuel gas supply path for supplying a fuel gas to the fuel cell stack between the fuel cell stack and an ejector connected in a circulation path for recirculating a fuel off-gas ejected from the fuel cell stack back to the fuel gas supply path, the temperature sensor detecting the gas temperature of the fuel gas supplied to the fuel cell stack; and an injector control unit that controls an injector which is located upstream of the ejector in the fuel gas supply path and supplies the fuel gas to the fuel cell stack, the injector control unit that, when the gas temperature is higher than a preset threshold, increases the supplied amount of the fuel gas by the injector, as compared with the case where the gas temperature is equal to or below the threshold.SELECTED DRAWING: Figure 1

    【課題】燃料電池システムにおいて、圧力センサの凍結を抑制する。【解決手段】燃料電池スタックが搭載された燃料電池車両の制御装置は、燃料ガスを燃料電池スタックに供給する燃料ガス供給路において、燃料電池スタックと、燃料電池スタックから排出された燃料オフガスを燃料ガス供給路に再循環させる循環路に接続されているエジェクタと、の間に配置された温度センサであって、燃料電池スタックに供給される燃料ガスのガス温度を検出する温度センサから、検出されたガス温度を取得するガス温度取得部と、燃料ガス供給路においてエジェクタの上流に配置されて燃料電池スタックに対して燃料ガスを供給するインジェクタを制御するインジェクタ制御部であって、ガス温度が予め設定された閾値よりも高い場合に、ガス温度が閾値以下である場合に比べて、インジェクタによる燃料ガスの供給量を増大させるインジェクタ制御部と、を備える。【選択図】図1
