摘要:
A hydrogen storage tank has an outer cylinder and a cylindrical hydrogen storage module within the outer cylinder spaced apart from an inner peripheral surface of the outer cylinder to provide a hydrogen passage therebetween. The cylindrical hydrogen storage module includes a lamination having a plurality of hydrogen storage units filled with powdery hydrogen absorption material and a hydrogen absorption and desorption surface on an entire outer peripheral surface, while interposing a heating/cooling element between ones of adjacent units. First and second main passages penetrate the lamination in a lamination direction of the units, and permit heating fluid and cooling fluid to flow therethrough. Sub passages branch from the main passages and extend over within each of the heating/cooling elements.
摘要:
A mixed powder of AlH3 and MgH2 is ball-milled in a hydrogen atmosphere while applying force of 5 G through 30 G (in which G is gravitational acceleration), and the thus-obtained milled product is dehydrogenated to produce a hydrogen storage material. The hydrogen storage material comprises an amorphous phase containing an Al—Mg alloy as a mother phase, and a crystalline Al phase having a maximum length of 100 nm or less, the crystalline Al phase being distributed as a dispersed phase in the mother phase.
摘要:
A hydrogen storage tank comprises a hydrogen adsorbent accommodated in a pressure-resistant container. The hydrogen adsorbent is capable of adsorbing and retaining hydrogen gas of a volume exceeding an occupation volume occupied by the hydrogen adsorbent itself. As for the hydrogen adsorbent, the amount of endothermic heat, which is generated when the adsorbed hydrogen gas is released, is not more than 16 kJ per mol of hydrogen molecules. The hydrogen adsorbent is prevented from leaking outside of the pressure-resistant container by a filter.
摘要:
To produce a hydrogen absorbing alloy powder which is an aggregate of alloy particles each including a metal matrix and added-components, an aggregate of metal matrix particles and an aggregate of added-component particles are used, and mechanical alloying is carried out. In this case, the relationship between the particle size D of the metal matrix particles and the particle size d of the added-component particles is set at d≦D/6. Thus, the milling time can be shortened remarkably.

A crystalline Al phase and a crystalline TiH2 phase each having a maximum length of 200 nm or less are dispersed in an amorphous phase containing an Al—Mg alloy to obtain a hydrogen storage material capable of reversibly storing and releasing hydrogen.
摘要:
An organometallic complex [Cu2(pyridine-3,5-dicarboxylate)2]n is provided by bonding a plurality of Cu2(pyridine-3,5-dicarboxylate)2 repeating units to each other. The organometallic complex can be obtained by the steps of dissolving copper acetate monohydrate or anhydrate and pyridine-3,5-dicarboxylic acid in a solvent, heating the solution at 50° C. to 140° C. for 24 to 168 hours to generate a reaction product, and then removing a guest molecule from the reaction product.
摘要:
An hydrogen tank filling apparatus includes a first hydrogen supply pipe for supplying hydrogen substantially at an atmospheric temperature from a high-pressure hydrogen storage tank to a hydrogen tank, a second hydrogen supply pipe for supplying cooled hydrogen from the high-pressure hydrogen storage tank to the hydrogen tank, and an internal tank temperature measuring unit for measuring the temperature inside the hydrogen tank. The first hydrogen supply pipe and the second hydrogen supply pipe are selectively switched by a control unit, depending on changes in the temperature inside the hydrogen tank.

摘要:
A fuel cell power system practical for use in a vehicle includes a fuel cell, a first hydrogen storage vessel having a first hydrogen absorbing material storing and releasing hydrogen, a catalytic combustor that heats the first hydrogen storage vessel so as to release hydrogen in order to supply hydrogen to the fuel cell, and a second hydrogen storage vessel having a second hydrogen absorbing material storing and releasing hydrogen and has a hydrogen release temperature that is lower than that of the first hydrogen absorbing material, the second hydrogen storage vessel releasing hydrogen as a fuel for the catalytic combustor under heating by waste heat from the fuel cell. Since the catalytic combustor can generate high temperature heat, a hydrogen absorbing material having a high hydrogen release temperature and a high hydrogen storage capacity per unit weight can be used as the first hydrogen absorbing material.
