Abstract:
There are disclosed a tank having a structure which achieves both a burst strength and a fatigue strength, and a manufacturing method of the tank. In order to realize this, in a tank comprising a liner (20), and an FRP layer (21) including a hoop layer (70P) and a helical layer (70H) formed by winding fibers (70) around the outer periphery of the liner (20), at least an innermost helical layer (70H) is formed as a smooth helical layer. When the smooth helical layer, i.e., a helical layer which does not have any unevenness or which has only little unevenness is formed, the unevenness can be prevented from being transferred to the hoop layer (70P) adjacent to the helical layer (70H). When structural bends (undulations) of the fibers (70) of the hoop layer (70P) are suppressed, a fatigue strength of the fibers (70) themselves can be enhanced.
Abstract:
The present invention relates to a container such as a container having non-cylindrical geometry, for uptaking, or storing, or releasing, or uptaking and storing, or uptaking and releasing, or storing and releasing, or uptaking, storing and releasing at least one gas, comprising at least one opening for allowing the at least one gas to enter and exit or at least one opening for allowing the at least one gas to enter and at least one opening for allowing the at least one gas to exit said container, and a gas-tight mechanism capable of storing the at least one gas under a pressure of from 1 to 750 bar, especially preferably from 50 to 80 bar, inside the container, said container further comprising a metallo-organic framework material comprising pores and at least one metal ion and at least one at least bidentate organic compound which is bound to said metal ion, as well as to a storage system and a fuel cell comprising said container, and to a method of using said container or said fuel cell for supplying power to power plants, cars, trucks, busses, cell phones, and laptops.
Abstract:
Safe storage of volatile compounds or elements is provided by utilizing storage configurations that take advantage of the diffusibility and release characteristics of cell-based materials, such as foam materials. Such configurations may provide storage of hazardous, liquefied gases in closed-cell foam material. Release of gas/liquid from the foam is restricted by the need for the gas to diffuse through the closed cells. Because rapid release is prevented, storage safety is greatly improved.
Abstract:
A fuel cell valve assembly for a fuel cell for combustion powered hand tools, said valve assembly (22) comprising a valve body, a valve stem (28) movcably disposed in the valve body and movable between a closed position in which, in use, fuel is prevented from flowing from the fuel cell and an open position in which fuel can flow from the fuel cell into a first fuel receiving passage that is defined by the valve stem and a valve stem cap (38) disposed on said valve stem, said valve stem cap having a second fuel receiving passage (46) that is in flow communication with said first fuel receiving passage and is provided with a plurality of exit holes (52) that each extend transversely of said second fuel receiving passage.
Abstract:
A filing device for use to manually or automatically refill a fuel cartridge using a separate fuel container or a second fuel cartridge is disclosed. The filing device provides for the sharing or fuel among numerous fuel containers and fuel cartridges in various consumer electronic values. Fuel cartridges can be filled in-situ using an adapter for connecting the fuel container to the fuel cartridge. The adapter includes an input connector and an output connector arranged to adapt various fuel containers and fuel cartridges together. The adapter can be arranged as a passive device or as an active device and can include pumps, valves, power sources and control units as desired.
