Abstract

A hydrogen generation device of the present invention comprises a first path (31) used to supply a raw material to a reformer (1) through at least a first desulfurization unit (2); a second path (32) used to supply the raw material to the reformer (1) through only the second desulfurization unit (3); a switch unit (6); a flow control unit (8) which selectively enables or inhibits a flow of the hydrogen-containing gas generated in the reformer 1 toward the second desulfurization unit (3); and a controller (12) configured to execute processing in such a manner that in at least either a time point before generation of the hydrogen-containing gas is stopped, or start-up, the switch unit 6 performs switching to select the first path (31), and the flow control unit (8) enables the flow of the hydrogen-containing gas, while the reformer 1 is generating the hydrogen-containing gas.
