  • Hydrogen supply device and hydrogen supplying method
    Publication number: 20060204799
    Abstract: A hydrogen supply device which generates hydrogen from hydrogen storing material which chemically stores hydrogen by a catalyst, wherein said device comprises valves on the fuel supply port and the exhaust port, and a valve controller which controls timing to opening and close the valves Fuel supply pressure is 2 to 20 atm. Hydrogen generation pressure is 5 to 300 atm. Exhaust pressure is atmospheric pressure to 0.01 atm.

  • Method of offering wall-thickness thinning prediction information, and computer-readable recording medium storing wall-thickness thinning prediction program, and method of planning piping work plan
    Patent number: 7089165
    Abstract: A wall-thickness thinning rate at a not-measured position is estimated using information having a small number of measured points. Simulation of behavior of fluid flowing inside a pipe line is performed based on wall-thickness data of pips and three-dimensional layout data of the pipe line including the pips using a computer, and simulated wall-thickness thinned data of the pipes composing the pipe line is calculated from change of the simulated behavior of fluid.

  • Hydrogen fuel manufacturing method and system with control program for use therein
    Publication number: 20050276749
    Abstract: A hydrogen fuel manufacturing system capable of efficiently producing each hydrogen fuel in accordance with a demanded quantity is disclosed. The system includes a hydrogen manufacturing apparatus for manufacturing hydrogen, more than two hydrogen fuel manufacturing apparatuses for manufacturing hydrogen fuels by letting the hydrogen produced by the hydrogen manufacturing apparatus change into a fuel-use form, wherein the fuel form to be manufactured by the hydrogen fuel manufacturing apparatuses is set to have more than two kinds. Additionally the system has a hydrogen fuel production volume receiver device for receipt of the information as to a hydrogen fuel production volume, thereby controlling the production volume of the hydrogen fuel being manufactured by the hydrogen fuel manufacturing apparatus, based on the hydrogen fuel production volume information as received by the hydrogen fuel production volume receiver device.
