HYDROGEN SUPPLY SYSTEM FOR DEVICE USING HYDROGEN AS FUEL

摘要

PROBLEM TO BE SOLVED: To provide a hydrogen supply system which can avoid the situation such as shortage of occluded hydrogen in the first storage section by frequent transferring of hydrogen from the first storage section to the second storage section. SOLUTION: This hydrogen supply system 1 comprises a reformer 3 and a hydrogen storage system 43. The hydrogen storage system 43 comprises a first storage section 44 having a first hydrogen absorber MH1 easily absorbing hydrogen, and a second storage section 51 having a second hydrogen absorber MH2 easily releasing hydrogen. Hydrogen from the reformer 3 is absorbed in the first storage section 44, and the hydrogen obtained by releasing the absorbed hydrogen is transferred to the second storage section 51 and absorbed there. At the start-up of the fuel cell 2, the occluded hydrogen in the second storage section 51 is released and supplied to the fuel cell 2. Provided that the maximum amount of occluded hydrogen in the second storage section 51 is 'a', the above-mentioned hydrogen transfer is performed under the condition of b>a, where 'b' is the amount of occluded hydrogen in the first storage section 44.
