Abstract:
The invention relates to a storage device (1) for storing a gas (20), in particular for storing gaseous hydrogen, comprising a first chamber (30) for receiving the gas (20) and a locking device (32) for closing and opening a flow path (33) connected to the first chamber (30). The storage device (1) according to the invention comprises an adjustment unit (40) for volume change of the first chamber (30). The invention further relates to a gas storage unit (100) comprising the storage device (1) according to the invention and to a method for the at least partial filling or emptying of the gas storage unit (100).
Abstract:
Described herein is a portable storage device that stores a hydrogen fuel source. The storage device includes a bladder that contains the hydrogen fuel source and conforms to the volume of the hydrogen fuel source. A housing provides mechanical protection for the bladder. The storage device also includes a connector that interfaces with a mating connector to permit transfer of the fuel source to a device such as a laptop computer. The refillable system comprises a hydrogen fuel source refiller that includes the mating connector and provides the hydrogen fuel source to the storage device. Hot swappable fuel storage systems described herein allow a portable hydrogen fuel source storage device to be removed from a fuel processor or electronics device it provides the hydrogen fuel source to, without shutting down the receiving device or without compromising hydrogen fuel source provision to the receiving device for a limited time.

Abstract:
A lightweight high pressure repairable piston composite tie-rod accumulator (10) that does not use a load bearing metallic liner. An exemplary accumulator (10) includes composite tie rods that sustain the axial stress induced by pressurization of the accumulator (10), while the shell (12) is designed such that it sustains the stress of pressurization in the hoop direction. The tie rods can be secured using a wedge-type tie rod retention mechanism. As a result, no pretension is applied to the tie rods and the composite shell (12) may be designed entirely for hoop stress.
Abstract:
PROBLEM TO BE SOLVED: To provide a method and an apparatus suitable for supplying a desorbed gas to reuse destination at stable gas pressure, while enhancing a recovery ratio of high purity hydrogen gas, in purifying hydrogen gas from a mixed gas containing hydrogen by using a pressure swing adsorption method.SOLUTION: A method for purifying hydrogen gas from a mixed gas containing hydrogen is provided in which a cycle including a hydrogen-enriched gas leading out step and a desorbed gas leading out step is repeated. In the hydrogen-enriched gas leading out step, by means of a pressure swing adsorption method using adsorption columns 10A-10D filled with an adsorbent, a mixed gas is introduced into the adsorption columns while the adsorption columns are in relatively high pressure, impurities in the mixed gas is adsorbed by the adsorbent and a hydrogen-enriched gas is led out from the adsorption columns. In the desorbed gas leading out step, the impurities are desorbed from the adsorbent by reducing pressure in the adsorption columns and the desorbed gas is led out from the adsorption columns. While the desorbed gas led out from the adsorption columns is introduced into a volume-changeable gas holder 2, the gas in the gas holder 2 is led out while keeping the pressure in the gas holder 2 substantially constant.
Abstract:
A pressure vessel includes: a barrel part disposed in a predefined square area and having a diameter corresponding to a length of one side of the square area; a first nozzle member disposed at one end of the barrel part; a second nozzle member disposed at an opposite end of the barrel part; and clamp rings disposed in the square area, positioned outside the barrel part, and configured to lock the first and second nozzle members to the barrel part, thereby improving spatial utilization and a degree of design freedom.
