Patent ID: 6919055

Claim:
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 heat exchange section having a rotary thermal storage through which the low and high temperature passages pass, the rotary thermal storage being driven to rotate; a reforming material supply section for supplying at least a part of reforming material to the low temperature fluid passage on an upstream side of the heat exchange section; a reforming section in which the reforming material is reformed to a reformed gas containing hydrogen after passing through the low temperature fluid passage; and a combustion gas supply section for generating and supplying a combustion gas to the high temperature fluid passage, wherein the rotary thermal storage rotates to move alternately between the low and high temperature fluid passages so that combustion heat of the combustion gas flowing in the high temperature fluid passage is transferred to the reforming material flowing in the low temperature fluid passage; and wherein the hydrogen supply device further comprises: a communicating passage through which the low temperature fluid passage communicates with the high temperature fluid passage; and pressurizing means located at any one position among the low temperature fluid passage on a downstream side of the heat exchange section, the communicating passage and the high temperature fluid passage on an upstream side of the heat exchange section, to increase pressure of gas flowing in the temperature fluid passage.
