Hydrogen supply device

A hydrogen supply device for producing and supplying hydrogen to a hydrogen consumption device, comprising:

• a low temperature fluid passage;
• a high temperature fluid passage;
• a first rotary thermal storage through which the low and high temperature passages pass, the first rotary thermal storage being driven to rotate;
• a reforming material supply section for supplying reforming material to the low temperature fluid passage on an upstream side of the first rotary thermal storage;
• and
• a combustion gas supply section for generating and supplying a combustion gas to the high temperature fluid passage on an upstream side of the first rotary thermal storage,
• wherein the first rotary thermal storage rotates to move alternately between the low and high temperature fluid passages so that the first rotary thermal storage constitutes a reforming section for catalytically reforming the reforming material flowing in the low temperature fluid passage to a reformed gas containing hydrogen upon receiving combustion heat of the combustion gas flowing in the high temperature fluid conduit.
