1. A hydrogen generator into which a mixed gas is run and out of which a reformed gas including hydrogen is discharged, the mixed gas including a mixture of a compound containing hydrogen atoms and oxygen or air, the hydrogen generator comprising:
an upstream side oxidation unit, a downstream side decomposition unit, a first temperature sensor which detects a temperature of the mixed gas immediately after passing through the upstream side oxidation unit, the first temperature sensor being disposed in a space located between the upstream side oxidation unit and the downstream side decomposition unit, the space being a place where the upstream side oxidation unit and the downstream side decomposition unit do not exist, a flow rate controller, and an electronic control unit that controls the flow rate controller, wherein the oxygen of the mixed gas burns part of the compound in the mixed gas in the upstream side oxidation unit so as to generate heat of combustion, and the heat of combustion is used to break down another part of the compound in the mixed gas in the downstream side decomposition unit to generate hydrogen, and the electronic control unit, through controlling the flow rate controller, controls at least one of a flow rate of the compound contained in the mixed gas flowing into the hydrogen generator and a flow rate of the oxygen or the air contained in the mixed gas so that the temperature of the mixed gas detected by the first temperature sensor is maintained substantially constant at a set temperature, the set temperature being a temperature at which the hydrogen concentration of the reformed gas becoming a predetermined concentration, the set temperature being preset in the electronic control unit. |
