Abstract:
1. A hydrogen generation apparatus comprising: a reformer that generates a hydrogen-containing gas by causing a reforming reaction of a raw material; a hydrodesulfurizer that removes a sulfur compound from the raw material; an adsorption desulfurizer that removes 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 that switches, 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 including a processor and a memory storing a program, wherein the program, when executed by the processor, causes the controller to perform operations including: when the reformer is generating the hydrogen-containing gas, setting the raw material flowing passage to the first raw material passage by the switch when an oxygen concentration in the raw material is in a first state, and setting the raw material flowing passage to the second raw material passage by the switch when the oxygen concentration in the raw material is in a second state, the oxygen concentration in the second state being higher than the oxygen concentration in the first state.
