A hydrogen-producing device is provided which can start up without receiving an energy supply from the outside. This hydrogen-producing device 1 is provided with an input unit 11 which is connected to a hydrogen source 41, a reformer 12 which produces a hydrogen-containing gas, a hydrogen storage container 13, a fuel battery 15 which generates power using the hydrogen-containing gas, and a control unit 18. The hydrogen storage container 13 is connected to a fuel hydrogen supply path 16 for supplying hydrogen to the fuel battery 15, and to an external supply path 17 which supplies hydrogen to an external load 42. The control unit 18 stores a threshold value of the hydrogen-containing gas necessary for start-up of the fuel battery 15, and controls the amount stored in the hydrogen storage container 13 to be greater than or equal to the amount necessary for start-up of the fuel battery 15. Further, when starting up the hydrogen-producing device, the fuel battery 15 generates power by receiving a supply of the hydrogen-containing gas stored in the hydrogen storage container 13 and supplies power to the reformer 12 from a power supply path 30. The reformer 12 starts up and hydrogen is produced.

A plasma gate device comprises a housing, a gas inlet, first and second dielectrics, and first, second, and third electrodes. The housing includes an internal reactor chamber. The gas inlet receives a source gas that flows to the reactor chamber. The first and second dielectrics are spaced apart from one another, with each dielectric including an upper surface and a lower surface.

The first and second dielectrics form boundaries of the reactor chamber. The first electrode receives a first electric voltage. The second electrode receives a second electric voltage. The first and second electric voltages in combination generate an electric field in the reactor chamber through which the source gas flows creating a positive ion plasma and a cloud of electrons. The third electrode attracts the electrons.
