To stop power generation of a fuel cell in a case of an occurrence of fuel gas leak in at least one compartment of either a tank compartment or a fuel cell compartment.SOLUTION: A fuel cell vessel includes: a fuel cell compartment where a fuel cell is installed; a tank compartment where a fuel tank is installed; fuel supply piping for supplying fuel from the fuel tank to the fuel cell; and a controller. The fuel supply piping includes at least two shutoff valves. Fuel gas detectors for detecting fuel gas which is fuel in a gas state are respectively installed in each compartment. The controller closes the shutoff valve in a compartment installed with the fuel gas detector which has detected the concentration of a standard value or more in the tank compartment and the fuel cell compartment when at least either one of the fuel gas detectors detects that the concentration of the fuel gas is the standard value or more.SELECTED DRAWING: Figure 3

    【課題】タンク区画および燃料電池区画の少なくともいずれかの区画内で、燃料ガス漏れが万が一発生した場合に、燃料電池の発電を停止させる。【解決手段】燃料電池船は、燃料電池が設置される燃料電池区画と、燃料タンクが設置されるタンク区画と、燃料タンクから燃料電池に燃料を供給する燃料供給配管と、制御部と、を備える。燃料供給配管は、少なくとも2つの遮断弁を有する。各区画内には、燃料の気体状態である燃料ガスを検知する燃料ガス検知器がそれぞれ設置される。制御部は、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、少なくともいずれかの燃料ガス検知器が検知したときに、タンク区画および燃料電池区画のうちで、規格値以上の濃度を検知した燃料ガス検知器が設置された区画内の遮断弁を閉塞させる。【選択図】図3
