METAL-OXIDE BASED APPARATUS FOR SOLAR HYDROGEN-GENERATION

摘要

A device for producing hydrogen by decomposing water is provided to need no separation film for separation of hydrogen because generated hydrogen is exhausted from a reactor at a state of being separated with other gas. A device for producing hydrogen by decomposing water comprises a reactive part and a light receiving part(600). The reactive part comprises the ceramic supporter, reaction bodies(510, 520, 530, 540), and a partition. The metal oxide is coated on the ceramic support. A reaction body contains gas inlets(511, 521, 531, 541) and gas exhaust ports(512, 522, 532, 542). The partition separates two or more reaction bodies. The reactive part is rotated or mobile. The light receiving part collects light and contains one or more light collecting surfaces at an upper part of the reaction body. The reactive part domain having the light collecting surface to the upper part of the reaction body forms a reducing zone by putting an inactive gas through the gas inlet. The reactive part domain having no light collecting surface to the upper part of the reaction body forms an oxidative region by putting steam through the gas inlet.
