By removing the contained oil vapor and water vapor, pure hydrogen gas is supplied at a predetermined pressure to demanding places such as automobiles, ships, small, medium and large hydrogen power plants, as well as recycling aluminum hydroxide and waste water undiluted solution to avoid polluting the natural environment and environment. It relates to a metal fuel manufacturing system for hydrogen gas production that enables the production of natural fuel.

Recently, the environmental problem that has become a global issue is one of the biggest problems that mankind needs to solve. In particular, the problem of global warming is a very urgent task to solve, and, Carbon dioxide emissions from the use of fossil fuels.

As a solution to this, research on a fuel cell that produces electric energy using hydrogen gas and research on using hydrogen gas as a fuel for an internal combustion engine are being actively conducted.

In particular, in the case of a fuel cell, since energy is generated without a combustion reaction of the fuel, there is no emission of toxic and successful pollutants generated in the combustion process of fossil fuels, and there is an advantage that the emission of carbon dioxide can be drastically reduced.

Despite these advantages, the use of hydrogen gas energy has not yet entered the commercialization stage, as derivative studies such as economical hydrogen gas production and development of a stable hydrogen storage medium are required. For example, hydrogen, which is generally stored in a high-pressure liquid state, has a very small ignition energy, and thus has a problem in stability, such as being easily ignited even by very fine static electricity.

As a prior document for solving the above problems, 'a device and method for generating hydrogen using a metal fuel' of Korean Patent Application Laid-Open No. 2018-0069290 (published on June 25, 2018) is supplied with a metal fuel and a liquid material to conduct a chemical reaction. a reactor for generating hydrogen through; a cylinder connected to the reactor and accommodated for a predetermined time before the metal fuel and the liquid material are supplied to the reactor; a metal fuel storage tank connected to the cylinder and supplying the metal fuel into the cylinder; a liquid material storage tank connected to the cylinder and supplying the liquid material into the cylinder; a first valve device installed in a passage between the cylinder and the liquid material storage tank, the opening and closing of which is adjustable; a second valve device installed in a passage between the cylinder and the metal fuel storage tank and adjustable in opening and closing; and a third valve device installed in the passage between the cylinder and the reactor, the opening and closing of which is adjustable.

The prior literature configured as described above includes the steps of supplying a liquid material into the cylinder by opening the first valve device; supplying metal fuel into the cylinder by closing the first valve device and opening the second valve device; supplying the metal fuel and the liquid material in the cylinder into the reactor by closing the second valve device and opening the third valve device; and generating hydrogen through a chemical reaction using the metal fuel and the liquid material in the reactor.

However, since the above-mentioned prior literature generates hydrogen by metal fuel and liquid material, it is easy to use on land, but there is a problem in that it is difficult to supply metal fuel for long voyages in the sea. In addition, in the case of a ship operating for a long time, there is a problem in that it is not easy to fill the metal fuel and liquid material.
