  • Hydrogen generator
    Patent number: 9162203
    Abstract: A hydrogen generator into which a mixed gas is run and out of which a reformed gas including hydrogen is discharged, which can reliably control the hydrogen concentration in the reformed gas to a desired concentration. The hydrogen generator is provided with an upstream side oxidation unit and a downstream side decomposition unit, burns part of the compound in the mixed gas in the oxidation unit using the oxygen in the mixed gas so as to generate heat of combustion, and uses the heat of combustion to break down another part of the compound in the mixed gas in the decomposition unit so as to generate hydrogen. The hydrogen generator is provided with a first temperature sensor controller.

  • Hydrogen generator and internal combustion engine provided with hydrogen generator
    Patent number: 8561578
    Abstract: A hydrogen generator provided with a cracker which cracks a compound containing hydrogen atoms and nitrogen atoms to generate hydrogen, a compound feeder which feeds the compound to the cracker, and an oxygen feeder which feeds oxygen to the cracker. The cracker includes catalyst particles which promote the cracking of the compound and catalyst particles which promote the oxidation of the compound. The cracker is fed with the compound and oxygen, causes the compound to oxidize to generate heat of oxidation, and uses the generated heat of oxidation to crack the compound.
