This hydrogen production apparatus is generally equipped with a reforming reactor for hydrocarbon raw materials and a reforming reactor. It consists of high-temperature and low-temperature shift reactors that convert CO in gas to H 2 . In this case, in order to avoid sulfur poisoning of the catalyst contained in the reforming reactor, it is usual to install a hydrodesulfurization reactor for hydrocarbon raw material on the upstream side of the reforming reactor. The hydrogen used in this hydrodesulfurization reactor can be covered by a part of the produced hydrogen if the above-mentioned hydrogen production device is in steady operation, but at the start of operation, a separate hydrogen source must be obtained. No, for example, a hydrogen cylinder must be used. However, considering the case where a fuel cell is installed in a remote area such as a remote island, it is not desirable to rely on a cylinder as a hydrogen source.

It is introduced into the desulfurization reactor 1. Part of the desulfurized hydrocarbon raw material is sent from the line 9 to the storage tank 6,
The rest is introduced into the reforming reaction tube 2 in the reforming furnace 3 through the line 10 and the steam supplied from the line 11 to be reformed. The reformed gas thus obtained is mixed with the steam from the line 11 to obtain the high temperature CO shift reactor 4 and the low temperature CO shift reactor 4.
