Abstract: The present disclosure relates to a hydrogen tank support apparatus, and the hydrogen tank support apparatus according to the present disclosure includes: a hydrogen storage tank; a frame portion on which the hydrogen storage tank is seated; and a sliding block portion configured to fix a nozzle portion of the hydrogen storage tank to the frame portion, wherein the sliding block portion includes a lower block portion fixed to the frame portion, an upper block portion coupled to the lower block portion in a concave-convex manner so that movement of the hydrogen storage tank is limited in a longitudinal direction and a width direction of the hydrogen storage tank, and a slide ball portion configured to surround an outer side surface of the nozzle portion, interposed between the lower block portion and the upper block portion, and configured to rotatably support the nozzle portion.

Abstract: The present disclosure discloses a high-pressure gas storage and supply device. The disclosed high-pressure gas storage and supply device includes a plurality of gas storage tanks that store a high-pressure gas therein and selectively discharge the stored gas, and a gas transport pipe including tank inlet/outlet lines respectively connected to the plurality of gas storage tanks to fill the gas in the gas storage tanks or discharge the gas stored in the gas storage tanks. Thus, in the present disclosure, the gas may be filled in or discharged from the gas storage tanks by the same one tank inlet/outlet line, and thus a structure for filling or discharging the high-pressure gas can be simplified.

Abstract: Disclosed is a valve device for a high-pressure gas storage tank. A valve device for a high-pressure gas storage tank according to the present disclosure includes a plurality of gas storage tanks having nozzle parts through which a gas is discharged, a block fixing part that accommodates the plurality of nozzle parts and has a gas flow path part, through which the gas discharged from the nozzle parts flows, in an internal space thereof, and an opening/closing part that is connected to the block fixing part and adjusts external discharge of the gas discharged from the nozzle parts and flowing to the gas flow path part.
