Description

[Detailed Description of the Invention] The present invention relates to a mobile production vehicle capable of producing hydrogen and oxygen gas using a water electrolysis device powered by solar cells and capable of high current efficiency electrolysis.

As equipment for producing hydrogen and oxygen gas,
It is already known to produce both gases by electrolyzing water in a water electrolyzer.

Conventionally, when using the above water electrolysis method, hydrogen and oxygen gas were produced in a factory using commercial power.
This was then filled into cylinders or the like and transported to the demand destination.

However, in the case of the above conventional example, when an emergency is required such as during a disaster, it takes a long time to move the cylinder from the factory to a specific location such as a disaster area, making it impossible to meet the urgent demand. In addition, energy costs are high due to the use of commercial power sources, and when relatively small amounts of hydrogen or oxygen gas are required in remote areas, costs including transportation costs may increase. There was a problem.

Therefore, in view of the above-mentioned conventional difficulties, the present invention uses solar cells as a power source to generate hydrogen even at the demand site or while driving.
The aim is to obtain a mobile production vehicle capable of producing oxygen gas and thereby meeting urgent demands and providing these gases at low cost.

The present invention will be described in detail below with reference to the illustrated embodiment. In FIG. is solar cell module 2,
2. Multi-stage module mechanism 3 that combines a large number of...
In addition, a water electrolyzer 4 powered by the solar cells of the modules 2, 2, etc. is installed inside the mobile body 1, and 5 and 6 in the figure are used to open and close the mobile body 1. Showing the door.

The multi-stage module mechanism 3 is normally in a folded state as shown in FIG. 1, but as shown in FIG. 3, all the solar cell modules 2, 2, . . . It is possible to freely deploy and support in multiple stages (three stages in the illustrated example) in an inclined deployed state.

On the other hand, the water electrolysis device 4 is constructed as shown in FIG.

That is, a water electrolyzer 7 consisting of a solid polymer electrolyte (SPE) type electrolytic cell is supplied with pure water 9 from a pure water tank 8, and at the same time, purified water 9 is supplied from a pure water production apparatus 10 to the pure water tank 8. The purified water from the water tank 11 is supplied with pure water, and a DC power is applied to the electrodes of the water electrolyzer 7 and the pure water production device 10 from the power supply section 12 formed by the solar cell modules 2, 2... There is.

In the illustrated example, this power supply section 12 is
2 is composed of only the solar cell modules 2, 2..., but when the modules 2, 2... are receiving sunlight during the day, the output of the solar cells is controlled by the controller. Even if some of the battery is consumed and the remaining output is used to charge the battery, and at night when there is no sunlight, electrolysis by the water electrolyzer is continued using the output from the charged battery. good.

The water electrolyzer 7 is connected to a hydrogen pipe 13 and an oxygen pipe 14 for discharging the generated hydrogen gas and oxygen gas, and the hydrogen gas flowing out from the hydrogen pipe 13 is supplied to a dryer 5 and a filling pump. 16
After drying and increasing the pressure (pressure 150 to 200 Kg/cm ² G), it is possible to fill the cylinders 17, 17...
Hydrogen gas can be supplied to external customers via a pressure regulator 18 and an on-off valve 19 from a hydrogen gas supply port 20 at the tip of the hydrogen pipe 13.

On the other hand, the oxygen gas containing water vapor discharged from the oxygen pipe 14 is returned to the pure water tank 8, where the water vapor is removed, and then led out from the pure water tank 8 through the pipe 21 to the dryer 22. , is dried and pressurized (approximately 150 kg/cm ² G) by the filling pump 23 so that it can be filled into the cylinders 24, 24, etc., and the oxygen at the tip of the piping 21 is Oxygen gas can be supplied to required locations outside through the gas supply port 27.

The filling pumps 16 and 23 are driven by a power source 12 using a solar cell.

In order to operate the mobile production vehicle with the above configuration, the mobile body 1 is towed by an indicator vehicle or the like and moved to the demand area, and the solar cell modules 2, 2, etc. are set to be capable of receiving light as shown in FIG. The pure water 9 is supplied from the pure water tank 8 to the water electrolyzer 7, and a DC voltage is applied to the electrode from the power supply section 12 using a solar cell. As a result, hydrogen gas and oxygen gas generated by electrolysis of pure water are transferred to the hydrogen pipe 13, the oxygen pipe 14, and the dryer 1, respectively.
5, 22, the cylinders 17, 24 are filled with filling pumps 16, 23, and if necessary, pressure regulators 18, 25 and on/off valves 19,
26, hydrogen gas and oxygen gas are supplied from the hydrogen gas supply port 20 and the oxygen gas supply port 27 to required locations of demand destinations.

Note that the hydrogen gas dryer 15 also serves as a gas reservoir.

Further, in the above description, the movable body 1 is of a towed type without a prime mover, but the movable body 1 may of course be of a self-propelled type such as a truck.

As explained above, the hydrogen and oxygen gas mobile manufacturing vehicle according to the present invention consists of a mobile body with wheels that can move freely, and a multi-stage contracting and deploying type in which a plurality of solar cell modules are stacked so as to be able to slide freely. It is equipped with a module mechanism and a water electrolysis device for filling a storage container with hydrogen gas and oxygen gas generated by water electrolysis treatment, and in order to contract the multistage module mechanism on the upper surface of the moving body, and
In order to deploy the multi-stage module mechanism obliquely from the top surface to one side of the moving body, the multi-stage module mechanism is supported via a plurality of telescoping support arms pivotally attached to the top surface and one side of the moving body, respectively. The present invention is characterized in that a water electrolysis device is installed inside a moving body, and the solar cell module of the multi-stage module mechanism and the water electrolysis device are electrically connected.

In the case of the mobile production vehicle of the present invention characterized by such a configuration, the following effects can be obtained.

One of them is that the mobile body can be moved to the required location at the appropriate time, and the produced hydrogen gas and oxygen gas can be filled into storage containers and supplied to the demand destination.
It can immediately respond to the supply of hydrogen gas and oxygen gas in emergencies and disaster situations, and requires almost no running costs due to the use of natural energy using solar cells as the DC power source for electrolysis.

The other method uses a contracting/expanding type multi-module mechanism in which a plurality of solar cell modules are slidably stacked on top of each other, and the multi-stage module mechanism is contracted on the top surface of a moving body, and Since it can be deployed at an angle from the top surface of the moving object to one side, the multi-stage module mechanism can be folded onto the moving object when not in use or when the moving object is running, and can be kept in a safe and bulky state. When using a multi-stage module mechanism, it can be expanded as described above to efficiently absorb solar energy, making it easy to use and practical.
