Embodiment 1

[0046] The step of reducing the particle size of the functional material, the step of hydrogenating the functional material, the step of forming a film, and the step of disposing the functional material will be described below.

[0047] When the functional material is a hydrogen storage alloy, materials such as hydrogen storage alloys are generally known such as calcium (Ca), lanthanum (La), magnesium (Mg), nickel (Ni), titanium (Ti), and materials such as vanadium ( V) the third element. These materials are mixed together, and the mixture is melted to manufacture cast hydrogen storage alloys such as La-Ni-based alloys and Mg-Ti-based alloys. Hydrogen is occluded in these alloys, followed by initial pulverization (initial pulverization) or mechanical pulverization to produce fine powders of hydrogen storage materials. Another method for producing fine powders of functional materials is as follows. Metal or alloy particles or Mg particles that are functional materials are pla...

Abstract

This invention relates to a power generating apparatus including two systems. In one of the systems, a hydrogen gas is generated by hydrolysis, and a hydrogen demanding unit generates electric power. In the other system, electric power is generated based on an oxidation-reduction chemical reaction of an electrode and ions. The power generating apparatus includes a hydrogen release unit with a hydrogen generating container within which a functional material has been mounted. Alternatively, a construction may be adopted in which the functional material is mounted on negative and positive electrodes and a battery element including the negative and positive electrodes and an electrolyte is provided within the container. The power generating apparatus further includes a hydrogen generating unit including a liquid container which generates a hydrogen gas both by hydrolysis, in which the functional material is reacted with water or an aqueous solution (an electrolysis solution), and by binding of hydrogen atoms which settle among crystals due to a quality change of the functional material by the hydrolysis, a first electrogenic unit in which the battery element in the hydrogen generating container generates electricity, a second electrogenic unit in which the hydrogen demanding unit generates electricity by a hydrogen gas produced in the hydrogen generating container, a control unit which applies electric power generated by the first electrogenic unit to a load device and, based on the load current amount, controls the amount of the hydrogen gas generated by the hydrogen generating unit.
