HIGH-PRESSURE TANK, METHOD OF CONTROLLING TANK SYSTEM AND TANK SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a high-pressure tank capable of dramatically reducing a probability of leakage of a gas filling a tank. SOLUTION: The tank prevents hydrogen gas in the tank from being leaked out via clearance between a mouthpiece 20 and a bung part 16 of the high-pressure tank 10 to atmospheric air because space between the mouthpiece 20 and the high-pressure tank 10 is sealed with an inside O-ring 44 and an outside O-ring 42. The tank prevents the hydrogen gas in the tank from being leaked out to the atmospheric air even though either of them occurs fault. The probability which the fault occurs on both of the inside and outside O-rings 44, 42 is very small and thus a tank system is configured as system which is very high in reliability.
