。When performing peak power cuts with high-temperature secondary batteries, the operating time is approximately two hours including 12 o'clock, so the waste heat generated during startup of the fuel cell system and the rated operating time until the time of use. (approximately 14% of the heat input) is supplied to the outside of the high-temperature secondary battery storage container through the duct, and the waste heat passing through the duct is adjusted by the thermometer signal. Since the temperature of a certain isothermal liquid is controlled, all of the large number of high-temperature secondary batteries stored in the high-temperature secondary battery storage container reach a temperature similar to -, and no batteries are inoperable. At night, when the fuel cell system is not in operation, the duct that carries waste heat is shut off using a damper and insulated. This causes a slight temperature drop, but by the time the battery is used, the temperature can be recovered sufficiently by waste heat from fuel cell operation. In order to compensate for the peak load power that occurs in a short time and has large fluctuations, using a high-temperature secondary battery,
The rated capacity of the fuel cell system can be reduced.

余剰電力を充電したものを負荷のピーク時に放電する。The secondary battery system 14 according to the present invention includes a gas turbine 1
1, and is preheated by this high temperature exhaust gas. Details of the secondary battery system 14 are shown in FIG. First, the configuration will be explained using this diagram. The secondary battery 16 is inserted into an isothermal liquid (such as sodium) 18 stored in a high temperature bath container 17 . If sodium is selected as this isothermal liquid 18,
In the unlikely event that the battery is damaged, sodium and sulfur from the battery will flow out into the isothermal liquid 18, so even a slight increase in the pressure in the high temperature practice @ 17 could lead to an accident such as a sodium fire. There isn't. The temperature of this isothermal liquid (sodium, etc.) is monitored by a thermometer 19, and the opening and closing of dampers 19 and 20 are controlled to perform temperature management. Note that when the secondary battery is not used, the dampers 20 and 21 are closed to prevent heat from leaking into the outside air. Here, the high temperature exhaust gas passes between the high temperature tank container 1G and the outer wall tank 22. This outer wall tank 22 is kept warm by a heat insulating material 23. To supply power from the secondary battery system, a vacuum circuit breaker 24 is connected, and surplus power that is not supplied to the load, out of the power generated in the fuel pond 7, is charged and discharged at peak load times.

時の温度を３５０℃で一定に保持しなければならない。In addition, here, the range indicated by the diagonal line downward to the left indicates the load power covered by the fuel cell 7 according to the present invention, and the range indicated by the diagonal line downward to the right indicates the surplus power from the power generated by the fuel cell 7 to the secondary battery. 16, and the range represented by the broken line represents the range in which the secondary battery is discharged to cover the load. Since the fuel cell 7 obtains electric power by controlling a chemical reaction, its responsiveness is somewhat poor, so it must generate electric power that is twice as much as the amount of electric power used. Therefore, surplus power is generated. In the present invention, this surplus power generated on the previous day is charged to the secondary battery 16, and the next day, this power is discharged at peak load. As a result, in the present invention, the capacity of the fuel cell to be configured can be reduced, and surplus power can be used effectively. Preheating of the high-temperature secondary battery 16 is a problem in operating this system 11 effectively. Sodium-sulfur' in high-temperature secondary batteries, i! Considering the battery, the temperature during battery operation must be kept constant at 350°C.

さらにと昇することができる。In the present invention, waste heat generated in the fuel tank 7 is utilized for this temperature control. Figure 4 shows the relationship between the amount of waste heat and the temperature of the high-temperature secondary battery. High-temperature (650°C) waste heat from the fuel cell is proportional to the operating status of the fuel cell, and as a gas, it accounts for 1 of the fuel heat input.
4% (see Figure 5) is discharged. In Fig. 4, the solid line indicates the amount of waste heat. Furthermore, the temperature of the high-temperature secondary battery used is indicated by a broken line. The temperature of the battery decreases during times when the fuel cell is not in use (nighttime, morning and evening) (not so low because the battery system is insulated with dampers 20+21 and heat insulating material 23)
No difference. ), but when the fuel cell starts operating,
The temperature is kept at the specified temperature (sodium-
In the case of a sulfuric acid battery, the temperature is approximately 350°C), and the battery can be discharged. In this way, the efficiency of the high-temperature secondary battery can be further increased by using the waste heat from the fuel cell as the standby energy (19% of the retained power) required to operate the high-temperature secondary battery.

容量を低減できる。According to the present invention, waste heat of the fuel cell is used as standby energy for the high-temperature secondary battery, thereby eliminating the need for standby energy, cutting the peak load on the secondary battery, and reducing the capacity of the fuel cell.
