<P>PROBLEM TO BE SOLVED: To provide a hydrogen production method by which the production of hydrogen can be carried out stably and efficiently. <P>SOLUTION: The hydrogen production method includes: a fuel reforming step of generating a hydrogen-containing reformed gas by an endothermic reaction from an elemental hydrogen-containing fuel; a step of generating heat for power generation and the endothermic reaction using the reformed gas and an oxidizing agent; a shift reaction step of converting carbon monoxide and steam in the reformed gas to hydrogen and carbon dioxide; a hydrogen separation step of separating hydrogen from a gas containing the hydrogen and the carbon dioxide by the shift reaction step; a hydrogen storage step of storing the hydrogen separated in the hydrogen separation step; a hydrogen storage quantity detection step of detecting the storage quantity of the hydrogen stored; and a step of monitoring a detected value by the hydrogen storage quantity detection step, wherein when the detected value decreases below a predetermined value, the supply quantity of the oxidizing agent is decreased and the supply quantity of the fuel is increased, and when the detected value of the hydrogen storage quantity detection means increases to the predetermined value, the supply quantity of the oxidizing agent is increased and the supply quantity of the fuel is decreased. <P>COPYRIGHT: (C)2009,JPO&INPIT |
