Patent ID: 8303917

Claim:
A hydrogen producing system, comprising: a seawater activating apparatus for activating seawater present within a sealed space at a high temperature and a high pressure using energy provided from high-temperature, high-pressure steam injected into the sealed space and for draining activated high-temperature, high-pressure seawater from said activating apparatus, said seawater activating apparatus having: a sealed tank having sealed space for admitting seawater therein, an inlet port for introducing seawater into the sealed space, a drain port for draining the activated high-temperature, high-pressure seawater, and steam injection means for injection of high-temperature, high-pressure steam into said sealed space; a pressure feed means for feeding the activated high-temperature, high-pressure seawater drained from the drain port; a duct apparatus for producing hydrogen from the activated high-temperature, high-pressure seawater fed by the pressure feed means by receiving and passing the activated high-temperature, high-pressure seawater fed by the pressure feed means, said duct apparatus including at least one seawater pipe, each seawater pipe of said at least one seawater pipe having a section of any of the shapes of triangle, pentagon, hexagon, and octagon; and a separating apparatus that is structured and arranged to separate hydrogen produced in the duct apparatus from seawater introduced into the separating apparatus through the interior of the at least one seawater pipe.
