A hydrogen system includes: a generator which generates hydrogen-containing gas; a storage which stores the hydrogen-containing gas generated by the generator; a first gas passage which connects the generator and the storage; a housing which houses the generator, the storage and the first gas passage; a second gas passage in which the hydrogen-containing gas discharged from the first gas passage to an outside of the housing flows; a first valve provided to the second gas passage; a third gas passage in which the hydrogen-containing gas discharged from the storage to the outside of the housing flows; a second valve provided to the third gas passage; and a controller which opens at least one of the first valve and the second valve.

Hydrogen system

A hydrogen system including: a hydrogen production apparatus that produces hydrogen; a hydrogen storage apparatus that stores produced hydrogen; a first flow path, wherein hydrogen discharged from the hydrogen production apparatus flows into the hydrogen storage apparatus through the first flow path; a second flow path, wherein hydrogen discharged from the hydrogen storage apparatus flows into a hydrogen-using apparatus through the second flow path; a casing that houses the hydrogen production apparatus, the hydrogen storage apparatus, the first flow path and at least part of the second flow path; a third flow path, wherein hydrogen discharged from at least one of the hydrogen production apparatus, the hydrogen storage apparatus, the first flow path and the at least part of the second flow path flows outside the casing through the third flow path; a first valve provided in the third flow path; and a controller that opens the first valve.

A hydrogen generating apparatus includes a reformer generating hydrogen-containing gas through a reforming reaction, a raw material supplier supplying a raw material to the reformer, a reaction gas supplier supplying reaction gas other than the raw material to the reformer, a hydro-desulfurizer removing a sulfur compound in the raw material supplied to the reformer, a recycle flow passage through which part of the hydrogen-containing gas generated by the reformer is supplied to the hydro-desulfurizer, a closing device that closes the recycle flow passage, and a controller that, when stopping operation, closes the closing device and controls the raw material supplier and the reaction gas supplier such that the raw material and the reaction gas are supplied to the reformer, before a temperature of the reformer drops down to a temperature at which deposition of carbon from the raw material on a reformation catalyst disposed inside the reformer is suppressed.

Hydrogen generating apparatus, fuel cell system, and methods of operating them

When a user sets water power using a water power adjustment switch in a remote control device, a controller controls the period of pressure fluctuations, the width of pressure fluctuations, and the central pressure of the discharge pressure of a pump on the basis of a signal transmitted by radio from the remote control device. When the user sets the divergent angle of washing water using a washing area adjustment switch in the remote control device, the controller controls the divergent angle of the washing water sprayed from a posterior nozzle on the basis of the signal transmitted by radio from the remote control device. Consequently, the washing water supplied to a side surface of a cylindrical swirl chamber from a first flow path in the posterior nozzle is sprayed from a spray hole as dispersed spiral flow, and the washing water supplied to a lower part of the cylindrical swirl chamber from a second flow path in the posterior nozzle is sprayed from the spray hole as linear flow.
