To provide a self-dimming system including: a main body section which is configured by a pair of transparent substrates arranged to face each other and to be separated from each other, and a frame body holding the pair of transparent substrates and forming a gap together with the pair of transparent substrates; a dimming section which is arranged in the gap and provided with a dimming element whose optical properties are reversibly changed by hydrogenation and dehydrogenation of the dimming element; a power-generating equipment which is arranged in the main body section; a hydrogen suction and discharge section which, when receiving electric power generated in the power-generating equipment, generates hydrogen by performing electrolysis and supplies the hydrogen to the gap and which, when not receiving electric power generated in the power-generating equipment, generates electric power by using the hydrogen in the gap; and control means which controls whether or not electric power generated in the power-generating equipment is supplied to the hydrogen suction and discharge section.

Self-dimming system

A hydrogen storage method is provided which enables a hydrogen storage alloy to store hydrogen up to a maximum hydrogen storage amount thereof in excess of a generally known theoretical value. In a hydrogenation step, a hydrogen storage ratio calculated as an atomic weight ratio between hydrogen and the hydrogen storage alloy is obtained beforehand as a theoretical value, a pressure at which the hydrogen storage alloy stores hydrogen up to the theoretical value is set as a first pressure value, a pressure value ten or more times greater than the first pressure value is set as a second pressure value, and pressure is increased up to the second pressure value. In a dehydrogenation step, the pressure is decreased from the second pressure value to or below the first pressure value. The hydrogenation step and the dehydrogenation step are repeatedly executed.

Hydrogen storage method

A hydrogen storage alloy unit comprises a porous bodyhaving a large number of holes (spaces)allowing hydrogen atoms to pass through, and a hydrogen storage alloy covering a surface of the porous body, inclusive of surfaces of the holes thereof. The hydrogen storage alloy includes a hydrogen storage base formed of a hydrogen storage material, and a catalytic layer covering a surface of the hydrogen storage base. The porous bodyis formed of an assembly of hydrogen storage fibersformed by vapor-depositing the hydrogen storage alloy onto nanofibers.

A hydrogen sensor using a hydrogen-absorbing alloy containing an Mg&#x2014;Ni-based alloy and a Zr&#x2014;Ti-based alloy includes a substrate (), a hydrogen reaction layer () formed on the substrate () and containing the Mg&#x2014;Ni-based alloy and the Zr&#x2014;Ti-based alloy, and a first catalyst layer () formed on the hydrogen reaction layer () and capable of accelerating hydrogenation of the Mg&#x2014;Ni-based alloy.

Hydrogen-absorbing alloy and hydrogen sensor using the alloy

A hydrogen storage alloy comprises a hydrogen storage base formed of a mixture of magnesium and an alloy, such as a magnesium-nickel alloy, a magnesium-titanium alloy, a magnesium-niobium alloy, a magnesium-manganese alloy, or a magnesium-cobalt alloy, and a catalytic layer covering a surface of the base. A hydrogen storage alloy unit includes the hydrogen storage base and a porous body including an assembly of nanofibers. The alloy may be vapor-deposited onto the assembly of nanofibers. The nanofibers may be tangled to provide spaces between the fibers for the passage of hydrogen molecules. The nanofibers in one example are also porous. A catalytic layer of platinum may cover a surface of the hydrogen storage base.
