- the shape of the tank 1 1 2 can be reduced. Therefore, when the hydrogen storage device is used as, for example, a fuel tank of a fuel cell vehicle, it is advantageous in mounting.
- FIG. 7A shows a perspective view of the hydrogen storage device according to the fifth embodiment of the present invention
- FIG. 7B shows a cross-sectional view taken along the line CC in FIG. 7A.
- the hydrogen adsorption member 1 4 0 and the liquid hydrogen storage unit 1 5 0 are arranged in the horizontal direction.
- the liquid hydrogen storage unit 150 is provided with a cylindrical liquid hydrogen receiving tray 180.
- the bottom of the liquid hydrogen pan 1 80 is in contact with the tank 1 1 2.
- the liquid hydrogen tray 1 80 can be formed of a SUS-based material or aluminum.
- the liquid hydrogen supplied through the liquid hydrogen inlet pipe 120 is first stored in the liquid hydrogen receiving tray 180.
- the liquid hydrogen tray 1 80 has a lower heat capacity than the tank 1 1 2, so that liquid hydrogen bumping can be suppressed. Further, since the bottom of the liquid hydrogen receiving tray 1800 is in contact with the tank 1 1 2, the liquid hydrogen receiving tray 1 80 can promote heat transfer from the liquid hydrogen to the tank 1 1 2.
- hydrogen gas may be taken out from the hydrogen gas discharge pipe 1 30, or a hydrogen extraction pipe having a smaller diameter than the hydrogen gas discharge pipe 1 3 0 may be provided to supply liquid hydrogen (large amount Hydrogen gas is discharged from the hydrogen gas discharge pipe 1 30 and is used when hydrogen gas is used (when a small amount of hydrogen gas needs to be released). You may make it take out hydrogen gas from a take-out pipe o
- the ratio between the volume occupied by the hydrogen adsorbing member 140 and the volume occupied by the liquid hydrogen storage unit 150 in the heat insulating container 110 is appropriately determined in consideration of the purpose of use of the hydrogen storage device. There is no particular limitation. In the present invention, the flow path connecting the internal space (liquid hydrogen reservoir) and the outside
- Liquid hydrogen introduction pipe Z hydrogen gas discharge pipe is preferably arranged so as to surround the outside of the tank.
- the hydrogen gas discharge pipe 1 3 0 in FIG. 7B may be disposed so as to be wound around the tank 1 1 2.
- the hydrogen storage device of the present invention can store hydrogen for a long period of time, it can be suitably used for a hydrogen storage device for a fuel cell vehicle using hydrogen gas as a fuel.
