no. 1 Embodiment approach
[0021] figure 1 A schematic configuration of the fuel cell system 10 as the first embodiment is shown. The fuel cell system 10 is an installed power generation system using a fuel cell, and includes a power generation facility 20 using the fuel cell, a cooling device 30 provided outside the power generation facility 20 , and a power supply from the cooling device 30 into the power generation facility 20 . A cooling system 40 for cooling the refrigerant. The power generation facility 20 includes a plurality of fuel cell units 22 housed in a container 21 provided, and a unit control unit 23 (in the figure 1 Described as “U-ECU 23 ”), it is a power generation facility that supplies electric power to the outside by generating electricity by at least one fuel cell unit 22 under the control of the unit control unit 23 . The cooling device 30 is a cooling device that circulates and supplies a refrigerant for cooling to each of the plurality of fuel cells 22 in the power generation ...
no. 2 Embodiment approach
[0060] Figure 5 This is an explanatory diagram showing a schematic configuration of a fuel cell system 10B as a second embodiment. The fuel cell system 10B replaces the temperature sensor 24 (see figure 1 ) and includes temperature sensors 110 provided in the vicinity of each fuel cell 100, respectively. In addition, the fuel cell system 10B replaces the unit control unit 23 (see figure 1 ) and includes a unit control unit 23B that controls each of the fuel cell control units 500 using the measurement values input from each of the temperature sensors 110 , as will be described later. The fuel cell system 10B is different from the fuel cell system 10 of the first embodiment except for these points (refer to figure 1 ) the same structure.
[0061] Image 6 This is a control flowchart of the unit control unit 23B in a state where the operation of the fuel cell system is stopped. In step S110B, the unit control unit 23B acquires the ambient temperature Ta of each fuel cel...
no. 3 Embodiment approach
[0071] Figure 7 This is an explanatory diagram showing a schematic configuration of a fuel cell system 10C as a third embodiment. The fuel cell system 10C replaces the unit control unit 23 (see figure 1 ) and includes a unit control unit 23C, and includes a temperature sensor 611 that measures the temperature of the primary side refrigerant flowing in the device supply line 612 and supplies the measured value to the unit control unit 23C. In addition, in the fuel cell system 10C, each fuel cell unit 22 replaces the fuel cell control unit 500 (refer to figure 1 ) and includes a fuel cell control unit 500C that controls the fuel cell cooling system 400 using the measurement value of the temperature sensor 611 supplied from the unit control unit 23C as described later. The fuel cell system 10C is provided with the fuel cell system 10 of the first embodiment except for these points (refer to figure 1 ) the same structure. In the fuel cell system 10C, in addition to the contro...
