Title:
HYDROGEN GAS LEAKAGE PREVENTION DEVICE
Document Type and Number:
Japanese Patent JP2023140685
Kind Code:
A
Abstract:
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
