To reduce hydrogen gas leakage while reducing cutoff of unnecessary hydrogen gas at collision in a fuel-cell vehicle in which a tank is arranged outside a side member in a longitudinal direction of the fuel-cell vehicle.SOLUTION: A hydrogen gas leakage prevention device 1 comprises a pair of side members 3 arranged apart from each other in a longitudinal direction of a fuel cell vehicle 100 while extending in a cross direction of the vehicle 100, and a hydrogen gas storage tank 10 arranged outside the side member 3 in a longitudinal direction of the vehicle 100. In this device, the hydrogen gas circulation from the tank 10 to a pipeline 20 is cut off by a cutoff valve 50 when collision of the vehicle 100 is detected by a collision detection sensor 40 arranged outside the pipeline 20, through which the hydrogen gas in the tank 10 circulates, in the longitudinal direction of the vehicle 100. Thereby, leakage of hydrogen gas can be reduced at the time of collision while reducing cutoff of unnecessary hydrogen gas.SELECTED DRAWING: Figure 3

    【課題】サイドメンバよりも燃料電池自動車の左右方向の外側にタンクが配置されている燃料電池自動車で、衝突時に不要な水素ガスの遮断を低減しつつ水素ガスの漏洩を低減する。【解決手段】燃料電池自動車100の前後方向に延在しつつ燃料電池自動車100の左右方向に互いに離間して配置された一対のサイドメンバ3と、サイドメンバ3よりも燃料電池自動車100の左右方向の外側に配置され、水素ガスを貯蔵するタンク10とを備えた水素ガス漏洩防止装置1で、タンク10の水素ガスが流通する配管20よりも燃料電池自動車100の左右方向の外側に配置された衝突検知センサ40によって燃料電池自動車100の衝突が検知されたときに、遮断弁50によりタンク10から配管20への水素ガスの流通が遮断されるため、衝突時に不要な水素ガスの遮断を低減しつつ水素ガスの漏洩を低減できる。【選択図】図3
