To suppress fuel cell stack deterioration and stabilize fuel cell stack power generation.SOLUTION: A control unit (96) of a vehicle fuel cell system (10) makes a first determination to determine whether a vehicle is stopped, estimates the amount of water collected at the bottom of the fuel cell stack on the basis of the amount of power generated by the fuel cell stack (12), makes a second determination to determine whether the water volume is greater or less than a water volume threshold, and controls the opening and closing of a valve (58) on the basis of the results of the first determination and the second determination.SELECTED DRAWING: Figure 1

    【課題】燃料電池スタックの劣化を抑制し、燃料電池スタックの発電を安定させる。【解決手段】車両用の燃料電池システム(10)の制御部(96)は、車両が停車しているか否かを判定する第1判定を行い、燃料電池スタック(12)の発電量に基づいて燃料電池スタックの下部に溜まった水量を推定し、水量が水量閾値より多いか少ないかを判定する第2判定を行い、第1判定の結果と第2判定の結果とに基づいて弁(58)の開閉を制御する。【選択図】図1
