摘要:
A high pressure tank has a cylindrical liner and a fiber reinforced plastic layer which covers the outer surface of the liner. At least one end of the liner is separable. The liner includes a cylindrical liner body and a lid. An O-ring is located between the contact surfaces of the liner body and the lid in the circumferential direction. Each contact surface has a seal surface which contacts the O-ring. One of the liner body and the lid has a deformable portion which deforms toward the seal surfaces. The structure can securely seal the separated portions of the liner when the high pressure tank is in a high pressure state.

A pressure tank includes a liner separated into a cap and a main body. A shell covers the outer surface of the liner. The shell is formed of a fiber reinforced plastic. A heat exchanger is arranged in the liner. A header is connected to the heat exchanger. The heat exchanger is supported on the liner by fastening the header to the cap or the main body.

An object-to-be-soldered (92) is accommodated in a sealable chamber (17). An internal pressure (P) of the chamber (17) is raised to a normal pressure (Po) or higher by feeding a reducing gas to the chamber (17). A soldering of a semiconductor element (12) with respect to a circuit board (11) is carried out in the pressurized state. The pressurized state indicating a set pressure (P1) (for example, 0.13 MPa) is maintained in a solder melting period (t3 to t7) until the molten solder (33) is solidified (t7) after the solder (33) starts melting (t3). Accordingly, voids are inhibited from being generated in the solder after being solidified.

In a hydrogen storing tank (solid filling tank) in which a hydrogen absorbing alloy (solid) is filled, a heat exchanger for executing heat exchange with the hydrogen absorbing alloy is constructed by laminating alternately first heat-transferring fins formed in corrugated plate shape and second heat-transferring fins formed in flat plate shape. Partitioned portions that are partitioned by the first heat-transferring fins and the second heat-transferring fins restrict movement of hydrogen absorbing alloy powders (MH powders) in a subsiding direction. Therefore, movement of the MH powders can surely be prevented by not using members that has no concern with the heat exchange and reduces an amount of filled MH powders and a volume in which the heat exchanger is provided.

In a fuel cell system 10, a refrigerant channel 70 that circulates refrigerant is configured to exchange heat between the refrigerant and each of a fuel cell 30, a hydrogen storage tank 20 having a hydrogen storage alloy, and a radiator 50. The hydrogen storage alloy has a higher absorption temperature at which absorption and release become equilibrium under the predetermined hydrogen pressure than the temperature of the fuel cell 30 in a steady-state operation. The refrigerant after cooling the fuel cell carries the heat generated by hydrogen absorption to the hydrogen storage alloy during storing from the tank 20 and facilitates absorption of hydrogen.

A hydrogen-storage container which demonstrates a high hydrogen-storage capacity, which is reduced in mass, and which is suited to be installed in an automobile is provided. In a hydrogen-storage container holding a hydrogen-occlusion alloy in which hydrogen is occluded, an air gap portion formed in the container is filled with hydrogen gas whose pressure is above a plateau equilibrium pressure of hydrogen gas contained in the hydrogen-occlusion alloy at a temperature of a location where the hydrogen-storage container is installed. This hydrogen-storage container has a liner made of metal or resin, and a fiber-reinforced resin layer provided outside the liner.
摘要:
A hydrogen storage apparatus that includes multiple gas storage tanks that each house a storing/adsorbing material and through the interior of which a fluid travels is provided. The gas storage apparatus 10 includes roughly cylindrical gas storage tanks 20 that house hydrogen-storing alloy. The multiple gas storage tanks 20 are disposed longitudinally parallel to each other in an ordered fashion such that roughly triangular prism-shaped empty spaces are formed between multiple adjacent hydrogen storage tanks 20. Coolant paths through which coolant flows are formed in these roughly triangular prism-shaped empty spaces. These coolant paths are thermally connected to the hydrogen-storing alloy in the gas storage tanks 20 via constituent members of the gas storage tanks 20 and via heat transfer plates 28 disposed on the gas storage tanks 20.
