The generated power is determined. The amount of the fuel gas supplied to the fuel cell 31 is also calculated by the control device 39 with respect to the output current and the fuel utilization factor of the fuel cell 31 to control the fuel supply device 32.
- the exhaust gas generated by the power generation of the fuel cell 31 passes through the heat exchange 40, the circulating water is warmed and hot water can be stored in the hot water storage tank 42 for use.
- the fuel utilization rate of the fuel cell 31 is normally set as high as possible in order to increase the power generation efficiency. That is, consuming as little fuel gas as possible in order to obtain a predetermined output current will increase the fuel utilization rate.
- the solid electrolyte fuel cell 31 is different from the polymer electrolyte fuel cell 1. Therefore, since the power generation efficiency is higher than the exhaust heat recovery efficiency, the amount of hot water stored will be reduced if the same operation as a polymer fuel cell is performed.

- the fuel cell 31 can be quickly shifted to a temperature at which the maximum power can be supplied to the power load. Even if it responds quickly, power can be supplied to the load. At this time, the amount of hot water stored can be increased because the amount of exhaust heat increases as compared with the case without reducing the fuel utilization rate.
- the fuel cell 31 increases the combustion energy of the remaining fuel, thereby allowing the fuel cell 31 to maximize the power to the power load. It is possible to transfer to a temperature that can be supplied in a short time. Further, at this time, the amount of exhaust heat increases as compared with the case where the fuel utilization rate is not lowered, so that the amount of stored hot water can be increased.

As a result, it is possible to further reduce the decrease in the operating temperature of the fuel cell 31 and increase the amount of stored hot water. This is because when the power load from the fuel cell 31 is reduced, the fuel cell 31 does not perform reverse power flow, and thus the generated power is reduced in accordance with the power load. If the fuel utilization rate remains constant, the operating voltage of the fuel cell 31 decreases, and the power generation efficiency of the fuel cell 31 decreases until the operating temperature can be increased again. , The amount of hot water storage decreases. However, at this time, it is possible to improve these problems by controlling the fuel utilization rate.

It can be canceled when the accumulated time falls below a certain value.
- the exhaust heat priority mode When the exhaust heat priority mode is effective, the power generation operation is performed at the fuel usage rate of 75% in the normal operation. If the exhaust heat priority mode is enabled, it is determined whether the forced exhaust heat mode is active. The forced exhaust heat mode always reduced the fuel utilization rate regardless of the operating conditions. It is a state to drive in the state. This mode is effective when the consumption of hot water in the household is extremely large and hot water runs out frequently.

- the amount of fuel gas can be controlled more precisely according to the state of the fuel cell than in one-step control, it is possible to suppress consumption of fuel gas more than necessary, and more efficient control. It can be performed.
- a determination is made based on the operation time, and if the operation time is nighttime (for example, between 24:00 and 6:00), the fuel utilization rate is reduced to 60% and the power generation operation is performed. In ordinary households, the state where the load is minimal often continues at night. At this time, the module temperature of the fuel cell 31 is lowered. Therefore, by reducing the fuel utilization rate and increasing the amount of fuel gas to be supplied, the decrease in module temperature can be reduced.
