To reduce thermal load on a fuel cell.SOLUTION: A fuel cell cooling system mounted on a vehicle is provided, having a cooling medium flow channel. The fuel cell cooling system further has: a cooler that cools cooling medium in a cooler flow channel; a fuel cell that is cooled by heat exchange with the cooling medium in a fuel cell flow channel; a heat-generating body that generates heat when being actuated and that is cooled by heat exchange with the cooling medium in a heat-generating body flow channel; a first pump delivering the cooling medium in the fuel cell flow channel toward the downstream side; a second pump delivering the cooling medium in the heat-generating body flow channel toward the downstream side; and a control circuit. When the vehicle is actuated, the control circuit carries out: a first step of actuating the first pump while the second pump is stopped; and a second step of actuating the second pump in addition to the first pump when a temperature of the cooling medium in the fuel cell flow channel or the cooler flow channel becomes higher than a first reference value during the first step.SELECTED DRAWING: Figure 2

    【課題】 燃料電池に加わる熱的な負荷を低減する。【解決手段】 車両に搭載された燃料電池冷却システムであって、冷媒の流路を有する。冷却器流路内の前記冷媒を冷却する冷却器と、燃料電池流路内の前記冷媒との熱交換によって冷却される燃料電池と、作動時に発熱するとともに発熱体流路内の前記冷媒との熱交換によって冷却される発熱体と、前記燃料電池流路内の前記冷媒を下流側へ送り出す第1ポンプと、前記発熱体流路内の前記冷媒を下流側へ送り出す第2ポンプと、制御回路と、をさらに有する。前記車両の起動時に前記制御回路が、前記第2ポンプが停止している状態で前記第1ポンプを作動させる第1工程と、前記第1工程中に前記燃料電池流路または前記冷却器流路内の前記冷媒の温度が第1基準値を超えると前記第1ポンプに加えて前記第2ポンプを作動させる第2工程を実施する。【選択図】図2
