Abstract:
An electrochemically active hydrogen diffusion barrier which comprises an anode layer, a cathode layer, and an intermediate electrolyte layer, which is conductive to protons and substantially impermeable to hydrogen. A catalytic metal present in or adjacent to the anode layer catalyzes an electrochemical reaction that converts any hydrogen that diffuses through the electrolyte layer to protons and electrons. The protons and electrons are transported to the cathode layer and reacted to form hydrogen. The hydrogen diffusion barrier is applied to a polymeric substrate used in a storage tank to store hydrogen under high pressure. A storage tank equipped with the electrochemically active hydrogen diffusion barrier, a method of fabricating the storage tank, and a method of preventing hydrogen from diffusing out of a storage tank are also disclosed.
Abstract:
The tank is made up of a plurality of elementary tanks such as tubes (20) connected in parallel to at least one manifold device (30, 32), and it includes closure valves enabling any one of the elementary tanks to be isolated in response to a drop in the pressure contained therein.

PROBLEM TO BE SOLVED: To configure a fuel tank to prevent a problem caused by aggressive properties of liquid stored within the tank and a problem caused by cracks of a diaphragm when the diaphragm is used in the fuel tank.SOLUTION: The diaphragm (3) comprises a polymer material and is sealed and held as a counter bearing within a recess (4) of an outer wall (1) of the tank by an elastic ring (2) having an approximately C-shaped cross section.
Abstract:
PROBLEM TO BE SOLVED: To create an assembly having outlet holes therein through which a fluid flows out while preventing leakage thereof, the fluid being allowed to be dispensed with by way of both a valve shaft and a valve shaft adapter fixed thereon. SOLUTION: A valve assembly 22 is for dispensing a fluid, equipped with a valve body 24 and a valve shaft 28 slidably disposed within the interior thereof, while the valve shaft 28 has an outlet hole 32 disposed at the tip end thereof. A valve shaft adapter 38 is attached to the tip end of the valve shaft. The valve shaft adapter 38 comprises at least one adapter outlet hole 52 so as cause the fluid to be allowed to be dispensed from the valve assembly 22 to be discharged. A dispenser for a fluid is equipped with a container 12, an inner bag to keep a dispensable fluid disposed in the container 12, and a valve assembly including a valve shaft adapter attached to the tip end of the valve shaft. The valve shaft adapter has adapter outlet holes therein through which dispensing from the valve assembly can be performed. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a storage tank for liquefied fuel which further reduces the amount of evaporated gas of stored low-temperature liquefied fuel while suppressing increase of volume and weight of a storage tank.SOLUTION: A storage tank 10A has a heat insulation material layer 14 formed on the outside of a barrier wall 12 of a container shape. The interior of the storage tank 10A is partitioned into two storage spaces V, Vby a parting plate 16, liquefied hydrogen LHis stored in a storage space Vand slush hydrogen SHis stored in a storage space V. A number of fins 18 are disposed on the parting plate 16, facilitate heat exchange between liquefied hydrogen LHand slush hydrogen SH, and reduce the amount of evaporated gas of liquefied hydrogen LH. A vent pipe 20 is connected to the storage space Vand fuel supply pipes 24a, 24b are respectively connected to the storage spaces V, V. Fuel supply pipes 24a, 24b are connected to a combustor 26 via a fuel main pipe 24.
