To provide a fuel battery ship that makes it possible, when fuel gas leakage occurs at a fuel battery, to inhibit leaked fuel gas from invading and residing in a cooling medium tank.SOLUTION: A fuel battery ship comprises a cooling system for cooling a fuel battery. The cooling system includes: a cooling medium tank that stores a cooling medium; a cooling medium circulation pipeline for making the cooling medium circulate between the fuel battery and the cooling medium tank; a cooling tank internal gas detector provided in the cooling medium tank; a cooling tank internal gas discharge pipeline connected to the cooling medium tank; and a cooling tank internal gas discharge valve provided on the cooling tank internal gas discharge pipeline. The fuel battery ship comprises a control unit for controlling opening/closing of the cooling tank internal gas discharge valve. The control unit opens the cooling tank internal gas discharge valve when the cooling tank internal gas detector detects a fuel gas concentration in the cooling medium tank being higher than a predetermined standard value.SELECTED DRAWING: Figure 2

    【課題】燃料電池において燃料ガス漏れが発生したときに、漏れた燃料ガスが冷却媒体タンクに侵入して滞留することを抑制することができる燃料電池船を提供する。【解決手段】燃料電池船は、燃料電池を冷却する冷却システムを備える。冷却システムは、冷却媒体を収容する冷却媒体タンクと、燃料電池と冷却媒体タンクとの間で冷却媒体を循環させる冷却媒体循環用配管と、冷却媒体タンク内に設置される冷却タンク内部ガス検知器と、冷却媒体タンクに接続される冷却タンク内部ガス放出配管と、冷却タンク内部ガス放出配管に設置される冷却タンク内部ガス放出バルブと、を有する。燃料電池船は、冷却タンク内部ガス放出バルブの開閉を制御する制御部を備える。制御部は、冷却媒体タンク内での燃料ガスの濃度が予め定められた規格値以上であることを冷却タンク内部ガス検知器が検知したときに、冷却タンク内部ガス放出バルブを開放する。【選択図】図2
