<Hydrogen gas analysis kit>
The hydrogen gas analysis kit according to one aspect of the present invention includes a solid collection sampler containing a solid collection agent. The solid collection sampler has been conventionally used for the analysis of the general atmosphere with humidity, but the use for the hydrogen gas having a low water content such as the hydrogen gas supplied to the fuel cell etc. is the subject of analysis. We were concerned that the components could not be collected. However, it has been found that impurities in hydrogen gas can be suitably collected by a solid collection sampler. The solid collection sampler is smaller and lighter than the high-pressure gas cylinder and liquid collection sampler. Therefore, according to the hydrogen gas analysis kit according to one aspect of the present invention, it is easy to carry and sampling can be performed in a small space. For example, it is easy to carry it to a place where hydrogen gas to be measured is present, such as a hydrogen station, and sampling can be easily performed on site. Moreover, since sampling can be performed by the pressure of the hydrogen gas itself to be analyzed, an external power source is not required. Therefore, it can be suitably used in places where it is difficult to secure a power source, such as outdoors such as hydrogen stations, and places where fire is strictly prohibited.

In addition, as an aspect of the method of providing the hydrogen gas analysis kit according to the present invention, the one assembled in the hydrogen gas analyzer 10 may be provided, and the parts for assembling are provided so that the user can assemble the kit. You may.

As shown in FIG. 1, the hydrogen gas analyzer 10 has a frame 26, a solid collection sampler 28 for an acid component, a solid collection sampler 30 for a base component, a solid collection sampler 32 for an aldehyde component, a dew point meter 18, and oxygen. It is formed by connecting the densitometer 20. The solid collection sampler 28 for the acid component, the solid collection sampler 30 for the base component, the solid collection sampler 32 for the aldehyde component, the dew point meter 18 and the oxygen concentration meter 20 are each one of the above-mentioned solid collection samplers and the like. be. In the description of the hydrogen gas analyzer 10, the "solid collection sampler, etc." includes a solid collection sampler 28 for an acid component, a solid collection sampler 30 for a base component, a solid collection sampler 32 for an aldehyde component, a dew point meter 18, and an oxygen concentration. Refers to a total of 20.

Further, a pressure regulator 14, a pressure gauge 15, and a flow meter 16 are connected to the frame 26. The pressure regulator 14, the pressure gauge 15, and the flow meter 16 may be provided with the hydrogen gas analysis kit according to one aspect of the present invention, or may be connected to those separately prepared by the user. Further, the frame 26 is provided with an injection port 12 and an exhaust port 24.

The injection port 12 is a connection port between the inside and the outside of the hydrogen gas analyzer 10 and is a receiving port for hydrogen gas to be analyzed. The hydrogen gas to be analyzed is introduced into the hydrogen gas analyzer 10 via the injection port 12. When the shape of the spout from the hydrogen gas to be analyzed is fixed, the shape of the spout 12 may be determined based on the shape of the spout.

The pressure regulator 14 is introduced into the hydrogen gas analyzer 10 to adjust the pressure of hydrogen gas before being introduced into a solid collection sampler or the like. The pressure of hydrogen gas is adjusted as appropriate according to the specifications of the solid collection sampler and the like.

The pressure gauge 15 is for measuring the value of the pressure adjusted by the pressure regulator 14. The pressure gauge 15 is connected to five flow meters 16 via pipes (some pipes are not shown).

The flow meter 16 measures the flow rate of hydrogen gas introduced into a solid collection sampler or the like. Five flow meters 16 are provided in the same number as the number of solid collection samplers and the like, and each of the five flow meters is connected to the solid collection sampler and the like via a pipe. Specific examples of the flow meter 16 are not particularly limited, and various conventionally known flow meters can be adopted, and for example, an area flow meter, an orifice flow meter, and the like can be used.

The exhaust port 24 is a connection port between the inside and the outside of the hydrogen gas analyzer 10 and is an opening for discharging the hydrogen gas that has passed through the inside of the hydrogen gas analyzer 10 to the outside. A pipe through which hydrogen gas passing through a solid collection sampler or the like passes joins one pipe and is connected to an exhaust port 24.

As described above, the hydrogen gas analyzer 10 does not require a high-pressure gas cylinder and a power source. Therefore, it can be constructed in a small size and light weight, can be easily carried, and can be sampled in a small space.

(Operation of hydrogen gas analyzer 10)
Next, the operation of the hydrogen gas analyzer 10 will be described.

First, as shown in FIG. 2, the hydrogen gas to be analyzed is introduced from the injection port 12. For example, the spout of the container in which hydrogen gas is stored is connected to the injection port 12, and hydrogen gas is injected into the hydrogen gas analyzer 10. The spout of the container in which the hydrogen gas is stored is, for example, the nozzle tip of a dispenser installed in a hydrogen station. When the hydrogen gas containment vessel is a high-pressure tank or the like, the pressure is appropriately reduced and the hydrogen gas is connected to the injection port 12. For example, a hydrogen station for a fuel cell vehicle supplies hydrogen gas having a high pressure of 70 MPa to a fuel cell vehicle or the like. It is more preferable to reduce the pressure of such a high-pressure gas to less than 1 MPa. This is because the handling of hydrogen gas becomes easier. The method for adjusting the pressure may be appropriately selected according to the desired pressure, and for example, the method described in JP-A-2016-114463 or an ultrahigh pressure pressure regulator can be used. Further, the flow rate may be appropriately adjusted so as to be a desired flow rate according to the type of the solid collection sampler or the like, and the flow rate may be different for each solid collection sampler or the like. Further, before introducing the hydrogen gas to be measured for the purpose of sampling, the gas in the hydrogen gas analyzer 10 may be introduced for the purpose of replacing the gas with the hydrogen gas. Regarding the solid collection sampler 28 for acid components, the solid collection sampler 30 for base components, and the solid collection sampler 32 for aldehyde components, each solid collection sampler is used to clean the pipes connected to each. It is more preferable to appropriately purge the hydrogen gas to be measured without aerating the sample. This is because if the inside of the solid collection sampler is ventilated, impurities in the hydrogen gas may be collected. For example, a bypass line may be used to provide a branch immediately before the upstream side of each solid collection sampler, and the bypass line may be connected to the exhaust line across the solid collection sampler.

The hydrogen gas injected into the hydrogen gas analyzer 10 from the injection port 12 flows through the flow meter 16 to each solid sampler or the like. During this time, the pressure of the hydrogen gas is appropriately adjusted by the pressure regulator 14 while being appropriately confirmed by the pressure gauge 15. Then, the flow rate of the hydrogen gas flowing into each solid collection sampler or the like is confirmed by the flow meter 16.

Next, the water concentration and the oxygen concentration in the hydrogen gas are measured by the dew point meter 18 and the oxygen concentration meter 20, respectively. In addition, the acid component, the base component, and the aldehyde component in the hydrogen gas are collected in the solid collection sampler 28 for the acid component, the solid collection sampler 30 for the base component, and the solid collection sampler 32 for the aldehyde component, respectively. ..

The hydrogen gas that has passed through each solid collection sampler or the like is discharged to the outside of the hydrogen gas analyzer 10 from the exhaust port 24.

As shown in FIG. 3, the hydrogen gas analyzer 10 in this modification has a branching point S that branches to introduce hydrogen gas injected from the hydrogen gas injection port 12 into each solid collection sampler or the like, and each solid. An orifice plate 40 is further provided between the collecting sampler and the like. The orifice plate 40 can control the gas flow rate by the orifice. Since the orifice plate 40 is provided, the gas can be introduced into each solid collection sampler or the like after controlling the flow rate of the gas injected into the hydrogen gas analyzer 10 within a desired range. Further, when the orifice plate 40 is provided, hydrogen gas having an appropriate flow rate can be supplied to each solid collection sampler or the like even if the flow meter 16 is omitted as in this modification. Therefore, the hydrogen gas analyzer 10 can be miniaturized. As a result, the hydrogen gas analyzer 10 can be easily carried.

In this modification, the embodiment in which the orifice plate is used as the flow rate controller has been described, but the flow rate controller in one aspect of the present invention may be any as long as it can adjust the flow rate of the gas to be introduced into the solid collection sampler. You can select it. For example, in addition to the above-mentioned orifice plate, a flow rate control valve, a mass flow controller, and the like can be mentioned. Further, as the flow meter 16, a flow meter with a valve may be used as a flow controller. Further, a flow meter with a valve is more preferable from the viewpoint of suitably adjusting pressure, flow rate and the like. An orifice plate is more preferable from the viewpoint of miniaturization of the hydrogen gas analyzer. The shape and size of the orifice plate are not particularly limited, and may be appropriately set according to the shape and size of the connecting pipe. Further, the pore diameter and the number of holes of the orifice plate are not particularly limited, and may be appropriately set in consideration of the pressure, flow rate, etc. of the gas to be introduced into each solid collection sampler or the like. Depending on the type of solid collection sampler or the like, different types of orifice plates may be provided for each solid collection sampler or the like. Further, in the present modification, the embodiment in which the orifice plate 40 is provided in front of the dew point meter 18, the oxygen concentration meter 30, and all the solid collection samplers has been described. However, in one aspect of the present invention, the flow rate controller is at least It suffices if it is provided between one of the above-mentioned branch points and one solid collection sampler.
