<p><P>PROBLEM TO BE SOLVED: To provide a hydrogen manufacturing apparatus using a thermochemical method and a method of using the same, in which a hydrogen yield can be increased, while maintaining nearly the same level of the scale of apparatus and heat efficiency required during hydrogen iodide decomposition. <P>SOLUTION: The hydrogen manufacturing apparatus using a thermochemical method includes: a hydrogen iodide generation vessel 3 which generates hydrogen iodide and sulfuric acid 25 by thermochemically decomposing iodine 23, sulfur dioxide 21 and water 22; a hydrogen iodide distillation vessel 4 which separates water 22 from the hydrogen iodide introduced from the vessel 3 where the hydrogen iodide 24 is generated and separated; a hydrogen iodide decomposition vessel 5 which decomposes separated the hydrogen iodide by a chemical reaction with germanium into hydrogen 26 and iodine 23; a hydrogen iodide-iodine recovering vessel 6 which recovers the decomposed iodine 23 and the undecomposed hydrogen iodine 24, a hydrogen purification vessel 7 which purifies the separated hydrogen 26; a sulfuric acid distillation vessel 1 which separates water 22 from sulfuric acid 25 introduced from the vessel 3 where the sulfuric acid 25 is generated and separated; and a sulfuric acid decomposition vessel 2 which decomposes the separated sulfuric acid 25 into sulfuric acid 21 and oxygen 27. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
