| 摘要 |
In the present invention, a method and apparatus for producing hydrogen by thermochemical water splitting are provided. The method for producing hydrogen of the present invention includes a reduction step of heating a high oxidation state redox material in an inert atmosphere to remove oxygen from the high oxidation state redox material, and thereby obtain a low oxidation state redox material and oxygen; and a hydrogen generation step of bringing water into contact with a low oxidation state redox material to oxidize the low oxidation state redox material and reduce the water, and thereby obtain a high oxidation state redox material and hydrogen. In the method for producing hydrogen of the present invention, the reduction step and the hydrogen generation step are performed switchingly in a same reaction vessel. Further, the apparatus for producing hydrogen of the present invention is used for performing the method for producing hydrogen of the present invention.
