HYDROGEN GENERATION APPARATUS, METHOD FOR DRIVING SAME, AND FUEL CELL SYSTEM

A hydrogen generation apparatus includes reformer (1) that reforms a raw material that contains hydrocarbon to generate a hydrogen-containing gas, a raw material supply device (2) and a water supply device (7) that supply the raw material and the water to reformer (1), a combustor (3) that combusts at least one of the raw material and the hydrogen-containing gas to heat reformer (1), and a reformer temperature detector (8). The hydrogen generation apparatus further includes independent activation power supply (5) which supplies power to at least raw material supply device (2) and water supply device (4), and controller (6). Controller (6) supplies power to auxiliary machinery including raw material supply device (2) and water supply device (7) from at least a first power supply other than independent activation power supply (5) during typical activation so as to activate the auxiliary machinery, and supplies power to the auxiliary machinery from only independent activation power supply (5) during special activation, in which power is not supplied from the first power supply, so as to activate the auxiliary machinery. The controller perform control of initiating water supply to the reformer.
