  • Hydrogen generation apparatus, laser reduction apparatus, energy conversion apparatus, hydrogen generation method and electric power generation system
    Patent number: 8137638
    Abstract: Object: To provide a hydrogen generation apparatus, a laser reduction apparatus, an energy conversion apparatus, a hydrogen generation method and an electric power generation system. Means for Solving the Problems: A hydrogen generation apparatus 10 according to the present invention includes: a reaction vessel 12 for retaining a metal element; a water reservoir 16 for supplying water into the reaction vessel 12; and a hydrogen recovery tube for recovering hydrogen gas and reaction energy generated by reaction of the metal element with the water. The present invention may further include a hydrogen storage device 26 for storing recovered hydrogen gas. Further, in the present invention, an oxide or a hydroxide of the metal element generated by reducing the hydrogen gas may be subjected to laser reduction to regenerate the metal element. A solar light pumped laser may be used for laser reduction.
