(57) Abstract:
(EN): Provided is a hydrogen generator capable of generating hydrogen using an inexpensive material. This hydrogen generator 1 is equipped with a water flow path portion 11 for inflow and outflow of a solution S from outside, a hydrogen generation portion 12 comprising a metal M that generates hydrogen H by reacting with the inflowing solution S, and a hydrogen recovery portion 13 for recovering the generated hydrogen H. The hydrogen generation portion 12 is arranged so that a surface coating of the metal M is detached by friction with the inflowing solution S to expose an active surface.
(FR): L'invention concerne un générateur d'hydrogène capable de générer de l'hydrogène à l'aide d'un matériau peu coûteux. Ce générateur d'hydrogène (1) est équipé d'une partie de trajet d'écoulement d'eau (11) pour l'entrée et la sortie d'une solution S depuis l'extérieur, d'une partie de génération d'hydrogène (12) comprenant un métal M qui génère de l'hydrogène H par réaction avec la solution d'entrée S, et d'une partie de récupération d'hydrogène (13) pour récupérer l'hydrogène H généré. La partie de génération d'hydrogène (12) est agencée de telle sorte qu'un revêtement de surface du métal M est détaché par frottement avec la solution d'entrée S pour exposer une surface active.
(JA): 安価な材料を用いて水素発生可能な水素発生装置を提供する。水素発生装置1は、外部から溶液Sを流入して流出する水流経路部11と、流入する溶液Sとの反応により水素Hを発生させる金属Mから成る水素発生部12と、発生させた水素Hを回収するための水素回収部13と、を備え、水素発生部12は、流入する溶液Sとの摩擦により自体である金属Mの表面被膜を剥離して活性面を露出させるように配置される。
