Title:
METHOD AND APPARATUS FOR SUPPLYING HYDROGEN AND PORTABLE CASSETTE FOR SUPPLYING HYDROGEN
Document Type and Number:
WIPO Patent Application WO/2001/096233
Kind Code:
A1
Abstract:
A method for supplying hydrogen which comprises producing a hydrogen gas from a methane gas using a catalyst (7) without generating carbon dioxide, reducing a metal oxide (10) utilizing the hydrogen gas, taking out a cassette (2) containing a reduced product from the metal oxide and attaching the cassette to a system requiring hydrogen, and reacting the reduced product with steam to produce hydrogen; and an apparatus for practicing the method. The method allows the construction of a system wherein hydrogen is produced without generation of carbon dioxide, a metal oxide is reduced with the hydrogen, and hydrogen can be supplied by the reaction of the resultant reduced product from the metal oxide, and thus the repeated production of hydrogen by the use of a cassette containing a metal oxide.
