To provide a hydrogen generating apparatus which can rapidly raise the temperature of a reforming catalyst and shortens the time required for restart.
When a hydrogen generating apparatus 10 is stopped, a first shutoff valve 26 and a second shutoff valve 28 are closed to form a closed space 32 in a reforming line 30. Hydrogen-based fuel is supplied to a reformer 18 in the closed space 32 and the hydrogen-based fuel causes reforming reaction by the residual heat of the reformer 18, whereby hydrogen becomes present in the closed space 32. When starting the hydrogen generating apparatus 10, the reformer 18 is heated to the combustion temperature of hydrogen or the combustion temperature of the hydrogen-based fuel. From this state, oxygen is made to flow therein by opening the first shutoff valve 26 and the second shutoff valve 28 to burn the hydrogen or hydrogen-based fuel. The reforming catalyst in the reformer 18 is rapidly heated to its activation temperature by heat generated by the combustion reaction of the hydrogen or hydrogen-based fuel.
