- the heater passage flow rate F h is calculated based on the pressure difference detected by the differential pressure sensor 17.
- the predetermined flow rate F 1 is a value determined based on the heating amount of the heater 16 calculated in step 4, and the cooling water is not excessively heated when the heater 16 is operated, that is, the cooling water. Is a flow rate that does not boil. This is because if the heater 16 is operated while the flow rate through the heater 16 is small, the temperature of the cooling water suddenly rises and the cooling water may boil locally.
- the predetermined flow rate F 1 may be a flow rate at which the cooling water does not boil even when heated by the heater 16. It is desirable to set it based on the heating capacity, the passage resistance of the heater 16, etc.

- the three-way valve 18 is controlled to adjust the circulation path of the cooling water (step 18). Specifically, the three-way valve 18 is controlled so that the cooling water flows through the cooling water circulation path 11 where the radiator 12 is disposed, instead of the radiator bypass path 15 where the heater 16 is disposed. By circulating the cooling water through the cooling water circulation path 1 1, the cooling water flows through the radiator 1 2. Heat is exchanged between the cooling water and the outside air by the radiator 1 2, and the cooling water that has passed through the radiator 1 2 passes through the fuel cell 10 0 in a cooled state. it can.
- the flow rate of the cooling water to be circulated is determined based on the fuel cell temperature T fc (step 19).
- the flow rate of the cooling water is calculated based on the fuel cell temperature T fc to be cooled. Specifically, when the fuel cell temperature T f c is high, a large amount of heat is required to cool the fuel cell 10, so the flow rate of the cooling water is increased.
- the cooling water pump 13 is controlled (step 20) to adjust the flow rate of the cooling water.
- step 14 a process when it is determined in step 14 that the fuel cell temperature T fc is lower than the predetermined temperature T 2 will be described.
- the fuel cell 10 is equal to or higher than the predetermined temperature T1 at which power generation is possible, and is lower than the predetermined temperature T2, which is the lower limit at which power generation efficiency decreases. Therefore, it can be said that the temperature is suitable for power generation treatment.
- step 21 supply of hydrogen and oxygen is started (step 21) and power generation processing is performed. Thereafter, similar to the warm-up process, the above process is performed while controlling the circulation path of the cooling water (step 3) and maintaining the fuel cell temperature ⁇ ⁇ c at an appropriate temperature.
- the warm-up process for heating and heating the fuel cell 10 and the cooling process for cooling the fuel cell 10 can be performed.
- the warm-up process is performed by heater 1 6 This is done by heating the cooling water and passing the heated and rejected water through the fuel cell 10. Since the heater 16 is controlled based on the heater passage flow rate F h, the heater 1 6 It is possible to prevent excessive heating of the cooling water due to the water, and to prevent boiling of the cooling water and the failure of the fuel cell system associated therewith.
- the flow of the cooling water that is the heat medium by the three-way valve 18 is calculated based on the temperature of the cooling water immediately after flowing out of the fuel cell 10 detected by the temperature sensor 14. It is controlled based on the fuel cell temperature T fc. That is, if it is determined that the fuel cell 10 needs to be warmed up based on the fuel cell temperature T fc, the three-way valve 18 will flow into the radiator bypass passage 15 according to a command from the ECU 20. To be controlled. In addition, when it is determined that the fuel cell 10 needs to be cooled by the fuel cell temperature T fc, the three-way valve 1 8 force cooling water is controlled to flow to the radiator 12 by a command from the ECU 20. .
- the flow rate of cooling water flowing into the fuel cell temperature control shown in FIG. Control of the heater 16 based on the heater passage flow rate F h) is useful.
- a temperature sensitive rotary valve that actively reacts to the temperature of the cooling water flowing in the cooling water circulation path 11 and switches the cooling water flow path can be used. Even in such a case, the process of the heater 16 based on the heater passage flow rate Fh in the fuel cell temperature control (especially S 6 to S1 0) is applicable.
- the processing of the heater 16 based on the heater passage flow rate F h is performed by a control valve such as a three-way valve 18 for controlling the flow rate of the cooling water to the heater 16 or the radiator 12 or the temperature sensitive rotary valve.
