摘要:
The technique of the invention manufactures a gas storage tank, which includes a gas absorbent/adsorbent and is capable of storing a high-pressure gas. The manufacturing process of a hydrogen storage tank first assembles a heat exchanger unit and packs the particles of hydrogen storage alloy into the heat exchanger unit. The manufacturing process then blocks hydrogen storage alloy filling holes used for packing the hydrogen storage alloy in the heat exchanger unit and attaches a detachable cover member to a hydrogen inlet. The manufacturing process subsequently locates the heat exchange unit filled with the hydrogen storage alloy in a cylindrical tank and narrows both ends of the tank to form joint openings. The manufacturing process then heat-treating the tank under water cooling and detaches the cover member. The manufacturing process attaches joint assemblies to the joint openings and forms a reinforcement layer around the outer circumference of the tank to complete the hydrogen storage tank.

An apparatus and method purify hydrogen from a mixed fluid containing gaseous hydrogen, gaseous oxygen, and liquid water. The apparatus has a mixed fluid channel through which the mixed fluid flows; a first gas channel through which a mixed gas containing gaseous hydrogen and gaseous oxygen flows; a second gas channel through which gaseous hydrogen or oxygen flows; a gas-liquid separating membrane forming a wall between the mixed fluid channel and the first gas channel, separating the mixed gas from the mixed fluid of the mixed fluid channel, and providing the separated mixed gas to the first gas channel; and a hydrogen or oxygen separating membrane forming a wall between the first gas channel and the second gas channel, separating gaseous hydrogen or oxygen from the mixed gas of the first gas channel, and providing the separated gaseous hydrogen or oxygen to the second gas channel.

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.

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.

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.
