Description

Container assembly for hydrogen system

The embodiment of the present invention relates to a container assembly for a hydrogen system.

Generally, when a power failure occurs due to a disaster, power is supplied to the disaster area where the power failure occurred using a small emergency power source. As the small power source, for example, a generator using a small diesel engine, a storage battery, or the like can be used.

Of these, generators using diesel engines generate power by supplying fuel from the outside. As a result, when the fuel is not well stocked or when the transportation network is interrupted due to a disaster and the fuel cannot be procured, the fuel is exhausted and power generation cannot be performed. For this reason, power cannot be continuously supplied to the disaster area.

A storage battery has a problem in that the time during which charged power can be supplied (discharged) is short. In addition, since the storage battery is easily discharged, it may be difficult to maintain the normally charged power.

It is conceivable to use a fuel cell as an emergency power source as an alternative to the diesel engine or storage battery described above. However, a fuel cell uses a fuel such as hydrogen to generate power. For this reason, when the fuel such as hydrogen is not sufficiently stocked or cannot be procured, there is a problem that hydrogen is lost, and power cannot be continuously supplied to the disaster area.

Also, it usually takes time to install fuel cells in disaster areas. This can make it difficult to quickly supply power to the disaster area. Furthermore, rubble and the like are often scattered in a disaster area. In such a case, it may be difficult to secure a space where a system including a fuel cell and a device attached thereto can be installed.

The water electrolysis apparatus 401 supplies electricity to water from which impurities have been removed (pure water), and electrolyzes the water into hydrogen and oxygen. In this way, hydrogen is produced. The produced hydrogen is supplied to the hydrogen storage device 50 and stored. On the other hand, oxygen generated in the water electrolysis apparatus 401 is released to the atmosphere. The water electrolysis apparatus 401 can be, for example, a solid polymer type (PEM) water electrolysis apparatus.

Among these, the fuel cell 601 is supplied with hydrogen from the hydrogen storage device 50, and the fuel cell 601 generates power using the supplied hydrogen. The fuel cell 601 can be, for example, a polymer electrolyte fuel cell (PEFC). The inverter 602 converts the electric power generated by the fuel cell 601 into electric power that can be used by the load unit 3.

The hot water storage tank 603 stores hot water generated using the heat generated by the power generation of the fuel cell 601 and supplies the stored hot water to the load unit 3. The radiator 604 is configured to dissipate heat generated by the power generation of the fuel cell 601. More specifically, the radiator 604 generates power from the fuel cell 601 when the amount of hot water supplied from the storage tank 603 to the load unit 3 is larger than the amount of hot water used in the load unit 3. Dissipate the heat generated in.

The fuel cell power generator 60 further includes measuring devices such as a gas sensor, a pressure gauge, and a flow meter. Data measured by these measuring devices is output to the control device 70 as a data signal.

As shown in FIG. 1, the control device 70 is configured to control each device constituting the hydrogen system 1. The control device 70 includes an arithmetic unit and a memory (not shown), and the arithmetic unit performs arithmetic processing using a program stored in the memory, thereby controlling each device.

The data measured by the measuring device of each device is input to the control device 70 as a data signal. Further, the amount of power used in the load unit 3 is input to the control device 70 as a data signal. For example, a data signal of the amount of power used by the load unit 3 during a predetermined time (30 minutes) is input to the control device 70. Further, the control device 70 includes a supply amount of power supplied from the power system 2, a use amount of hot water used in the load unit 3, an output amount of power output from the natural energy power generation device 10, and a power conditioner device. 20, the storage amount of the storage battery 202, the output amount of power output from the fuel cell power generator 60, the storage amount of water stored in the water storage device 30, the storage amount of hydrogen stored in the hydrogen storage device 50 Data such as the amount of hot water stored in the fuel cell power generator 60 is input as a data signal. Then, the control device 70 performs an operation based on the input data signal and outputs a control signal to each device of the hydrogen system 1. In this way, the control device 70 controls the operation of each device of the hydrogen system 1 and performs control so as to achieve optimum operation.

For example, the control device 70 performs control so that power is supplied from the hydrogen system 1 to the load unit 3 when the amount of power used by the load unit 3 is larger than a predetermined value in a normal state. I do. Here, the normal state means a state in which power is supplied from the power system 2 to the load unit 3. In this case, based on the output amount of power output from the natural energy power generation device 10, the output amount of power output from the fuel cell power generation device 60, the storage amount of the storage battery 202, and the like, power is appropriately collected from each device and loaded. Supply to part 3. Further, the control device 70 supplies hot water from the fuel cell power generator 60 to the load unit 3 based on the amount of hot water used in the load unit 3.

On the other hand, there is a case where power is not supplied from the power system 2 to the load unit 3 in the event of a power failure due to a disaster. When such an abnormality occurs, the control device 70 performs control to supply power from the hydrogen system 1 to the load unit 3. In this case, the control device 70 performs control so that the hydrogen generator 40 produces hydrogen using the power generated by the natural energy power generator 10 and the fuel cell power generator 60 generates power. Then, the control device 70 receives power from each device based on the output amount of power output from the natural energy power generation device 10, the output amount of power output from the fuel cell power generation device 60, the storage amount of the storage battery 202, and the like. Collected appropriately and supplied to the load section 3. In addition, the control device 70 supplies hot water from the fuel cell power generation device 60 to the load unit 3 even during an abnormality.

Incidentally, the control device 70 determines whether it is normal or abnormal. That is, the control device 70 determines whether it is normal or abnormal by monitoring the amount of power supplied from the power system 2. More specifically, when power is supplied from the power system 2, it is determined as normal, and the connection between the power system 2 and the hydrogen system 1 is maintained. On the other hand, when the power supply is not supplied from the power system 2 and the power supply is stopped, it is determined that there is an abnormality such as a disaster, and the connection between the power system 2 and the hydrogen system 1 is cut off. .

In addition, the control device 70 also determines the time zone. That is, the control device 70 determines whether the time zone is daytime or night based on the time, and controls each device based on the determined time zone.

Furthermore, the control device 70 also determines the weather. That is, the control device 70 determines the weather based on the output amount of power output from the natural energy power generation device 10. More specifically, when the time zone is daytime, the control device 70 determines that the weather is clear when the output amount of power output from the natural energy power generation device 10 is greater than a predetermined amount. If it is less than the predetermined amount, it is determined that the weather is cloudy or rainy. And the control apparatus 70 controls each apparatus based on the judged weather.

In addition to the above, the control device 70 controls the operation of the hydrogen generator 40 so as to produce hydrogen based on the amount of hydrogen stored in the hydrogen storage device 50.

In addition, the control device 70 determines that the total supply amount of the power output from the fuel cell power generation device 60 and the power supplied from the power system 2 is greater than the total power consumption used in the hydrogen system 1 and the load unit 3. In many cases, the electric power generated by the fuel cell power generation device 60 is stored in the storage battery 202 of the power conditioner device 20. More specifically, the control device 70 determines whether or not the total supply amount is larger than the total use amount. When the control device 70 determines that the total supply amount is larger than the total use amount, the power generated by the fuel cell power generation device 60 is output to the storage battery 202 and stored without being output to the load unit 3. Let Thus, in this Embodiment, the electric power generated with the hydrogen system 1 is used effectively.

Further, when the supply amount of hot water supplied from the fuel cell power generation device 60 to the load unit 3 is larger than the usage amount of hot water used in the load unit 3, the control device 70 is generated by the fuel cell power generation device 60. The warm water is returned to the water storage device 30. More specifically, the control device 70 determines whether or not the amount of hot water supplied is larger than the amount of hot water used. When the control device 70 determines that the supply amount is larger than the usage amount, the hot water stored in the fuel cell power generation device 60 is supplied to the water storage device 30 without being supplied to the load unit 3. Thereby, the water for supplying to the hydrogen generator 40 from the water storage apparatus 30 is securable. In this case, it is preferable to dissipate heat generated by the power generation of the fuel cell power generator 60 by the radiator 604.

Furthermore, the control device 70 controls each device of the hydrogen system 1 based on the output amount of power output from the natural energy power generation device 10.

For this reason, the electric power generated by the natural energy generator 10 is not supplied to the hydrogen generator 40 but is supplied to the load unit 3 via the power conditioner 20 and the storage battery of the power conditioner 20 202 is charged. In this case, the hydrogen generator 40 stops the production of hydrogen. The electric power stored in the storage battery 202 is not supplied to the hydrogen generator 40 because the production of hydrogen is stopped. That is, the storage battery 202 stops discharging.

The fuel cell power generator 60 generates power, and the power obtained by the power generation is supplied to the load unit 3. Further, the fuel cell power generator 60 generates hot water, and the generated hot water is supplied to the load unit 3.

Thus, in the case of normal time, hydrogen is manufactured using the electric power generated by the natural energy power generation device 10 which is a solar power generation device, and the hydrogen storage amount in the hydrogen storage device 50 is secured. In addition, surplus power generated by the natural energy power generation device 10 is supplied to the load unit 3, and power obtained by power generation using hydrogen by the fuel cell power generation device 60 is supplied to the load unit 3. The Therefore, the electric power generated by the natural energy power generation device 10 and the fuel cell power generation device 60 can be effectively used.
