Abstract
A hydrogen generation apparatus and a fuel cell system including: a reformer () configured to generate a hydrogen-containing gas by causing a reforming reaction of a raw material; a hydrodesulfurizer () configured to remove a sulfur compound from the raw material; an adsorption desulfurizer () configured to remove a sulfur compound from the raw material; a first raw material passage () through which the raw material that is supplied to the reformer not through the adsorption desulfurizer but through the hydrodesulfurizer flows; a second raw material passage () through which the raw material that is supplied to the reformer through the adsorption desulfurizer flows; a switch () configured to switch, between the first raw material passage and the second raw material passage, a raw material flowing passage through which the raw material flows; and a controller () configured such that when the reformer is generating the hydrogen-containing gas, the controller sets the raw material flowing passage to the first raw material passage by means of the switch if an oxygen concentration in the raw material is in a first state where the oxygen concentration is relatively low, and the controller sets the raw material flowing passage to the second raw material passage by means of the switch if the oxygen concentration in the raw material is in a second state where the oxygen concentration is relatively high.
