Claim:
1. A method of operating a hydrogen generator, comprising: removing a sulfur compound from a raw material by a hydrodesulfurizer which is heated by heat transferred from a hydrogen generation unit; generating a hydrogen-containing gas by the hydrogen generation unit by using the raw material including at least hydrogen and carbon; stopping the generating of the hydrogen-containing gas by stopping supplying the raw material to the hydrogen generation unit; detecting a temperature of the hydrodesulfurizer with a first detector; and thereafter, enabling an operation of re-supplying the raw material to the hydrogen generation unit via the hydrodesulfurizer if the temperature of the hydrodesulfurizer detected by the first detector is equal to or less than a first predetermined temperature, the first predetermined temperature corresponding to such a temperature of the hydrodesulfurizer at which carbon deposition from the raw material onto a hydrodesulfurization catalyst is suppressed.
