Description
The control unit 14 is communicated with the control device 20 by wire or wireless connection. For example, the control unit 14 performs the necessary control for operating the fuel cell unit 10 according to the control signals received from the control device 20. For example, the control unit 14 controls the operation of the DC-DC converter 12, DC-AC inverter 13, auxiliary equipment (not shown), etc. Examples of auxiliary equipment include pumps, blowers, and valves. The pumps and blowers, for example, send fuel gas and oxidizer gas to the fuel cell stack 11. The control unit 14 transmits to the control device 20, for example, data indicating the power generated in the fuel cell system 100, data indicating the cumulative number of starts of the fuel cell unit 10, data indicating the cumulative power generation time of the fuel cell unit 10, etc. The data indicating the power generated may, for example, be data indicating the magnitude of the current output from the fuel cell unit 10. The data indicating the cumulative number of starts of the fuel cell unit 10 is obtained, for example, by counting the cumulative number of times the switch (not shown) of the fuel cell unit 10, which is provided on the fuel cell unit 10, switches from OFF to ON. Data indicating the cumulative power generation time of the fuel cell unit 10 is obtained, for example, by counting the cumulative time during which the switch (not shown) of the fuel cell unit 10, which is provided on the fuel cell unit 10, was in the ON state. The control unit 14 is, for example, a computer equipped with a storage device that stores the program necessary for the operation of the fuel cell unit 10, and a processor that reads and executes the program from the storage device. The control device 20 can, for example, obtain data from the control unit 14 of each fuel cell unit 10, such as data indicating the power generated in the fuel cell unit 10, data indicating the cumulative number of starts of the fuel cell unit 10, and data indicating the cumulative power generation time of the fuel cell unit 10. In this way, the control device 20 can obtain information for each of the multiple fuel cell units 10 for each fuel cell unit 10.
