By the way, the biggest problem of the fuel cell is how to supply dangerous hydrogen gas to the fuel cell. Hydrogen is extremely volatile and easily explodes. Therefore, in order to handle the system as it is, the entire system must be 100% secure. Therefore, research on hydrogen storage alloys has been advanced. However, hydrogen storage alloys have many problems to be solved due to poor hydrogen absorption efficiency. The capacity remains at a level not exceeding 3% by volume, and it cannot be fueled as easily as the current gasoline. Further, since liquid hydrogen can be stored only at extremely low temperatures of less than minus 252.8 degrees Celsius, it becomes enormous even with a cooling device alone, and is not practical for use in homes and automobiles. In addition, fuel cells that use hydrocarbons as raw materials can be used as a by-product of hydrogen or methanol, when natural gas, a finite resource, is exhausted (around 2060).
This is a temporary device that needs to be switched to digestive gas.

In order to solve these problems, a method of repeatedly using water that can be circulated as a resource has been studied, and a method of extracting hydrogen gas therefrom has been demanded. Fuel for supplying hydrogen to the fuel cell includes gasoline,
Research on methanol, petroleum-based fuels, natural gas, biomass, digestive gas and the like has been performed for some time. However, although each has its own characteristics, gasoline production and sales infrastructure can be used at present, but the problems of recoverable reserves, greenhouse gas reduction and environmental pollution have not been solved. . Methanol can be chemically synthesized, and there is no fear of depletion of fossil fuels. However, there is a problem in that it requires an enormous amount of capital investment including production facilities, and thus has an economic burden.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of an energy supply system according to the present invention will be described with reference to the drawings. FIG. 1 is a system configuration diagram showing a basic configuration of a system of the present invention. In FIG. 1, reference numeral 1 denotes an electrolytic hydrogen generator, 2 denotes a gas storage, 3 denotes a fuel cell, and 4 denotes an inverter. Is shown. 5 is a junction box, 6 is various devices to which energy is supplied, 7 is a controller,
8 is a storage battery, 9 is a solar cell using renewable energy,
Shows various facilities such as wind power generation, evaporative pumping type hydroelectric power generation, and temperature difference convection power generation. As a result, an extremely clean integrated energy supply system can be constructed at the demand area.
The significance of long-distance power transmission and high-voltage power transmission will be diluted, and an independent and distributed integrated energy supply system that will also serve as more efficient disaster prevention equipment will be completed on a regional and household basis.

The energy supply system of the present invention comprises an electrolytic hydrogen generator, a gas storage for taking out hydrogen and oxygen from water by the electrolytic hydrogen generator and storing the hydrogen and oxygen, and a fuel cell receiving fuel supply from the gas storage. By using renewable energy as the primary energy of the configured system, heat and
It is intended to provide a combined power supply system. This is a cycle in which hydrogen and oxygen are extracted from water by combining a fuel cell and an electrolytic hydrogen generator, and this is used as a raw material for the fuel cell to generate electricity.A model that can use surplus generated gas as heat energy is also available. It is to be added to the world and to propose to the world as a new product. Fuel cells discharge pure water in the process of generating electricity, so the waste heat and wastewater contained in the fuel cells are also reused to create economical clean energy that is repeatedly circulated and economical, and widely available to the world What you want to do.

Various types of devices are known as the electrolytic hydrogen generator 1. For example, the Stuart water electrolysis hydrogen generator shown in FIG. 2 can be designed with a modular configuration according to needs, and the contents of the device include a gas generator, a compression device, a purification device, and a storage device according to the user's request included. The electrolyzer can be operated by a semi-automatic or fully automatic system with a minimum number of operating personnel, and the hydrogen generator can automatically generate a preset flow rate. In the system of the present invention, hydrogen and oxygen taken out by the electrolytic hydrogen generator are brown gas having a mixing ratio of 2: 1 and can be used without using a hydrogen storage alloy or a high-pressure cylinder for storing hydrogen. The fuel can be stored. Brown gas uses the above-mentioned electrolytic hydrogen generator using water as a resource, and it is generated by electrolysis.Therefore, there are few restrictions on the location conditions, and if it is limited to a direct combustion system such as a boiler, existing gas including electricity bills Compared to heavy oil and LNG, it has excellent economic characteristics of operating at less than half.

In addition, since brown gas is composed of atomic groups having a 2: 1 ratio between electrically extracted hydrogen and oxygen, it does not have the molecular structure of H ₂ found in ordinary electrolytic hydrogen, so that explosion occurs. It is commercially available without any danger and can be safely managed under normal temperature and normal pressure environment. In particular, Enaptech of South Korea has been studying generation efficiency, safety and stable supply for many years, and has succeeded in developing a large-scale generator that far surpasses other companies. Therefore, it is possible to omit the part called storage alloy or high-pressure tank for storing hydrogen, and by adopting a simple mechanism, it is advantageous to suppress the product price and promote the spread. System.

[0022] The gas generation condition is as follows.
It is placed in a generator and electrolyzed by a DC power supply to generate 2H + O single atom.
The gas has a calorific value of 8,350 kcal and a combustion temperature of 6,000 ° C. or higher. Moreover, about 3.2 m ³ of gas can be generated with 1 liter of water without generating CO and CO ₂ . In addition, since the gas itself has oxygen, it does not require external air and does not induce explosion, which is advantageous in terms of safety. By storing and storing the gas in the state of brown gas and separating and supplying hydrogen immediately before combustion to an internal combustion engine, which is a hydrogen engine, it is possible to apply the conventional technology.

Next, the brown gas generated by the electrolytic hydrogen generator 1 is supplied to the gas storage 2, and in the system of the present invention, when the electric energy is taken out and used, the energy is stored in the state of electricity. Instead of storing, store in gaseous form. A fuel cell 3 is further connected to the gas storage 2.
Converts DC power into AC power and supplies power to various devices / devices 6. Brown gas withstands compression up to 5 kg / cm ² and has the property of returning to water when pressurization is increased. Therefore, storage at a low pressure of 8 kg / cm ² or less enhances safety. The combined use of a hydrogen storage alloy can improve storage efficiency, but results in the loss of brown gas properties. Brown gas itself consists of a group of hydrogen atom 2 and oxygen atom 1, and metal hydrite (MH hydrogen storage alloy) stores only hydrogen and releases oxygen to the atmosphere without using it. However, this is because it is a loss component that does not contribute to power generation. Alkaline fuel cells have been used in outer space, and this brown gas contains hydrogen and oxygen, each of which is necessary for power generation, so it can be applied to the power demand of submarines and submarine cities. Can be. It can be applied to deep underground development, etc., and it is necessary to provide primary energy separately. There is such as collecting geothermal and claiming it depending on the situation
The method of reducing the overall efficiency can be combined by using the method of reducing with steam described in 11 and the energy of the vortex due to the temperature difference convection described in 12 above.

It is known that there are currently five types of fuel cells 3: solid polymer type (proton exchange membrane type-PEM), solid electrolyte type, phosphoric acid type, molten carbonate type and alkaline type. ing. As fuel cells for use in automobiles, research and development of mainly small and light polymer electrolytes are in progress, and ion-exchange membranes made of fluororesin are used as electrolytes.
A catalyst is applied to both sides of the membrane, and hydrogen ionized on the hydrogen electrode (fuel electrode) side is combined with oxygen on the air electrode (electric electrode) side to generate power. In such a case, the fuel stored in the tank is sent to the reformer like a current gasoline-powered vehicle, and the separated hydrogen is supplied to the fuel cell to generate electricity.
Conventionally, the form of rotating the motor has been researched and developed.However, in the apparatus of the present invention, since the brown gas is stored in the gas storage in the state of the brown gas, also on the fuel cell side,
A catalytic reformer for extracting hydrogen from conventional gas can be omitted, and gas can be directly introduced or only oxygen can be adsorbed, so that simplification can be realized and the stability of the device is improved. It is effective. However, research is needed to make it compatible with molten carbonate fuel cells (MCFC). In the application to other fuel cells, there are no technical elements that are difficult to commercialize, so it can be dealt with by changing the degree of improvement of the electrolyte.

Next, as in the third aspect of the present invention, a drainage circulation system for reusing wastewater discharged in the process of generating electricity by the fuel cell is provided connected to the fuel cell. In this case, as shown in FIG. 1, from the fuel cell 3, a drainage circulation system is connected to the electrolytic hydrogen generator 1, and water is resupplied to the electrolytic hydrogen generator 1. The conversion efficiency of the fuel cell is about 40%, which means that 60% is discarded as water.
Maintaining the link in the new manner of the present invention allows the entire water to be recovered and reused as a gas resource.

In order to start the electrolytic hydrogen generator 1, electric power from an external power supply is required, and when the fuel cell 3 is started in the same manner, external electric power needs to be supplemented. When both devices are activated, the electrolytic hydrogen generator 1 and the fuel cell 3 generate both gas and water flows, generate electric power, and maintain a state in which power can be continuously generated after the activation. As shown in FIG. 1, of the generated electric power, the electric power is supplied to the electrolytic hydrogen generator 1 through the inverter 4 and the controller 7, so that the operation is performed in a state where the electric power is supplied at this stage. In the energy supply system further combining the storage battery 8, the solar cell 9, and the like, the shortage is extracted from the renewable energy to realize self-sufficiency. When there is no load, it is taken out as electric power, and when there is no load, it can be stored in gas or the output can be adjusted to eliminate unnecessary cycles. Further, if the evaporative pumping type hydroelectric power generation system is added, it is possible to convert energy from heat energy to potential energy during a time when there is no demand for electric power.

Or, a circulating system for reusing waste heat or surplus brown gas is provided. For example, in FIG. 3, hot waste water is supplied to each living room and the like, and electric power generated from a fuel cell is supplied to a home via a controller and an inverter. And so on. The hot waste water can be used for heating or other purposes, and after use, is recycled by being recycled to the electrolytic hydrogen generator 1. Further, by connecting the solar battery 9 and the storage battery 8 to the controller, it is possible to adjust the stored power, and to supply and sell power to the outside of a home or a business. In addition, a combination with a normal commercial power supply and switching can be performed. When using solar cells or other renewable energy,
Electric energy can be extracted from the fuel cell through the electrolytic hydrogen generator, which is a gas generator, and solar power can be used without waste as long as there is sunlight. Other renewable energies, alone or in combination, constitute the system. Further, as in the invention according to claim 9, an external power supply means for supplying power from the fuel cell to the outside of the energy supply system of the present invention via an inverter, and the power supplied to the outside is provided.

This is a configuration for realizing a vehicle equipped with a fuel cell 3 having a capacity to cover the power for moving the vehicle and the power for moving the electrolytic hydrogen generator 1.
Normally, the fuel cell 3 performs rated operation, but when the vehicle is stopped, the output is reduced to adjust. Electric energy required for traveling is supplied from a storage battery. In addition, since no electric power is supplied from the storage battery while the vehicle is parked, surplus electric power is generated. Similarly to the above, the surplus electric power is collected in substation facilities provided in a home or a toll parking lot, and can be distributed to a neighborhood (grid link, reverse power flow is possible). If the parking lot collects and sells the surplus power generated by the fuel cell vehicle, the parking fee will be paid to the user, which may become a new type of parking lot service. In addition, this fuel cell vehicle saves energy with gas and a storage battery, and if there is no load, operation of the fuel cell can be suppressed and gas can be stored, and surplus gas can be released and assimilated to the atmosphere.

With such a configuration, it can be added to an existing gas station, and surplus electric power can be sold. When the electrolytic hydrogen generator 1 is used, the hydrogen fuel supply base which has been a concern can be set up in a short time.
It is also possible to use a resource such as commercial power or city gas as a backup, but this is an emergency measure and not a necessary condition. A state in which power can be exchanged with the commercial power source is maintained, and when there is another power selling company, a method of selecting one of them can be adopted. The hydrogen station operator is a power sales business,
Produced electricity and gas can also be sold.
