Document Type and Number:
Japanese Patent JP5443262
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel gas filling and supply system capable of preventing backflow without use of a check valve for each of a plurality of fuel gas tanks.SOLUTION: The hydrogen gas filling and supply system 10 includes: a hydrogen tank 50 with a large heat flux and a hydrogen tank 52 with a small heat flux; a hydrogen filling pipe 30 which connects the hydrogen tanks 50 and 52 in parallel; a hydrogen supply pipe 32, the one end of which is a merging portion of the hydrogen tanks 50 and 52 and the other end of which is connected to a fuel battery 34; and the check valve 60 which is provided in the merging portion of the hydrogen supply pipe 32. The check valve 60 blocks a flow from the hydrogen tank 50 to the hydrogen tank 52 when the pressure of the hydrogen tank 52 is lower than that of the hydrogen tank 50, and blocks a flow from the hydrogen tank 52 to the hydrogen tank 50 while the pressure of the hydrogen tank 52 is higher than that of the hydrogen tank 50 and lower than predetermined cracking pressure.
