In other words, even if the temperature of the combustion section 13 is higher than the first temperature, if the temperature of the fuel cell 11 is lower than the second temperature, or if the temperature of the fuel cell 11 is expected to drop below the second temperature, the control device 15 executes the second control without executing the first control.
- the second temperature may be determined, for example, based on the temperature of the fuel cell 11 when the fuel cell device 10 starts generating electricity.
- the drop in temperature of the fuel cell 11 below the second temperature may occur, for example, when the necessary fuel gas is not supplied to the fuel cell 11 due to an error in the gas flow meter or a gas leak caused by a crack in the fuel cell 11. Furthermore, if the necessary fuel gas is not supplied to the fuel cell 11, a misfire occurs and the temperature of the combustion section 13 drops. Therefore, if the drop in the temperature of the combustion section 13 detected by the first temperature sensor 16 continues, it can be expected that the fuel cell 11 will drop below the second temperature.

- the control device 15 may also execute the fourth control in priority over the first control until a predetermined time has elapsed since the fuel cell 11 started generating electricity.

- step S203 the control device 15 stores the amount of gas supplied. After storing, the process proceeds to step S204.
- step S204 the control device 15 reduces the amount of gas supplied by a predetermined amount. After this, the process proceeds to step S205.
- step S205 the control device 15 waits for a predetermined waiting time. After the waiting time has elapsed, the process proceeds to step S206.
- step S206 the control device 15 determines whether the temperature of the combustion section 13 is equal to or higher than the first temperature. If it is equal to or higher than the first temperature, the process returns to step S205. If it is not equal to or higher than the first temperature, the process proceeds to step S207.
- step S207 the control device 15 detects the time that has elapsed since the amount of gas supply was reduced in step S204. Furthermore, the control device 15 determines the heating time based on the calculated elapsed time. After the determination, the process proceeds to step S208.
- step S208 the control device 15 increases the gas supply amount from the gas supply amount stored in step S203 by an increase amount that is the same as the predetermined decrease amount by which the gas supply amount was decreased in step S204. After the increase, the process proceeds to step S209.

- the heating process is started, for example, periodically while the fuel cell device 10 is in operation.
- step S300 the control device 15 determines whether a predetermined time has elapsed since the fuel cell 11 started generating power. If the predetermined time has not elapsed, the process proceeds to step S301. If the predetermined time has elapsed, the heating process ends.
- step S301 the control device 15 stores the amount of gas supplied. After storing, the process proceeds to step S302.
- step S302 the control device 15 increases the amount of gas supplied by a predetermined increment. After the increase, the process proceeds to step S303.
- step S303 the control device 15 waits for a predetermined waiting time. After the waiting time has elapsed, the process proceeds to step S304.
- step S304 the control device 15 determines whether the temperature of the fuel cell 11 is less than the second temperature. If it is less than the second temperature, the process returns to step S303. If it is not less than the second temperature, the process proceeds to step S305.
- step S305 the control device 15 returns the gas supply amount to the supply amount stored in step S301. After returning it, the heating process ends.
- the fuel cell device 10 of this embodiment configured as described above executes a first control to reduce the amount of fuel gas supplied to the fuel cell 11 when the temperature of the combustion section 13 is equal to or higher than a first temperature, and executes a second control to increase the amount of fuel gas supplied to the fuel cell 11 in preference to the first control when the temperature of the fuel cell 11 is lower than a second temperature or when the temperature of the fuel cell 11 is expected to drop to or below the second temperature.
- the temperature of the combustion section 13 becomes high, the reformer 14 is overheated, which causes the deterioration of the reforming catalyst contained in the reformer 14 to progress, and the fuel gas discharged from the reformer 14 becomes hotter, which causes the temperature difference between different parts of the fuel cell 11 to increase.
- the fuel cell device 10 it is desired to prioritize the amount of power generation and power generation efficiency over suppressing both the deterioration of the reforming catalyst and the increase in the temperature difference in the fuel cell 11.
- the fuel cell device 10 having the above-described configuration can determine the situation in which it is desirable to improve the amount of power generated and the efficiency of power generation in the fuel cell 11, and prioritize execution of the second control, while suppressing deterioration of the reforming catalyst and the increase in the temperature difference in the fuel cell 11 when this control is feasible. Therefore, the fuel cell device 10 can suppress deterioration of parts other than the fuel cell 11.
- the fuel cell device 10 of this embodiment executes the first control when the current of the electric power generated by the fuel cell 11 is equal to or less than the current threshold. In other words, the fuel cell device 10 does not execute the first control when the current of the electric power generated by the fuel cell 11 is greater than the current threshold. If the amount of fuel gas is reduced when the current is not equal to or less than the current threshold, there is a risk of misfire. In such an event, the fuel cell device 10 having the above-described configuration can reduce the possibility of misfire.
- the fuel cell device 10 of this embodiment executes a third control to increase the amount of fuel gas supplied to the fuel cell 11 if the temperature of the combustion section 13 drops below the first temperature after the first control is executed.
- An excessive drop in temperature of the combustion section 13 causes a drop in the temperature of the fuel cell 11.
- the drop in temperature of the fuel cell 11 makes it difficult to respond to fluctuations in load.
- the fuel cell device 10 having the above-described configuration can bring the combustion section 13 closer to an appropriate temperature in response to an excessive drop in temperature of the combustion section 13 caused by the execution of the first control.
- the fuel cell device 10 makes it easier to respond to load fluctuations.
- the fuel cell device 10 of this embodiment increases the fuel gas so that the increase in the fuel gas in the third control is less than the decrease in the fuel gas in the first control executed immediately before the third control.
- the temperature of the combustion section 13 may again reach or exceed the first temperature, after which the temperature of the combustion section 13 may repeatedly drop and rise.
- the fuel cell device 10 having the above-described configuration can reduce the possibility that the temperature of the combustion section 13 will again reach or exceed the first temperature. Therefore, the fuel cell device 10 contributes to stabilizing the temperature of the combustion section 13.
- the fuel cell device 20 of this embodiment increases the fuel gas so that the time for increasing the fuel gas in the third control is less than the time for decreasing the fuel gas in the first control executed immediately before the third control.
- the fuel cell device 10 can suppress the increase in the fuel gas in the third control to less than the decrease in the fuel gas in the first control executed immediately before the third control in a simplified configuration, such as a configuration in which the absolute values of the increase and decrease in the fuel gas supply amount (flow rate) are the same.
- a fourth control that increases the amount of fuel gas supplied to the fuel cell 11 is executed in preference to the first control until a predetermined time has elapsed after the fuel cell 11 starts generating electricity.
- the ceramic part of the fuel cell 11 has a low temperature, so the internal resistance is high and the fuel cell 11 cannot output a large current of power. Therefore, early rated power generation is achieved by increasing the amount of fuel gas for a predetermined time from the start of power generation.
- the temperature of the combustion section 13 may temporarily rise above the first temperature.
- the fuel cell device 10 it is desired to prioritize the amount of power generation and power generation efficiency over suppressing both the deterioration of the reforming catalyst and the increase in the temperature difference of the fuel cell 11.
- the fuel cell device 10 having the above-mentioned configuration can execute an operation that prioritizes the amount of power generation and power generation efficiency while having a configuration that executes the first control.
- the present disclosure can also be embodied as a method or program for implementing the device, or as a storage medium on which a program is recorded (for example, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a CD-RW, a magnetic tape, a hard disk, or a memory card, etc.).
- a storage medium on which a program is recorded for example, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a CD-RW, a magnetic tape, a hard disk, or a memory card, etc.
- the implementation form of the program is not limited to application programs such as object code compiled by a compiler or program code executed by an interpreter, but may be in the form of a program module incorporated into an operating system.
- the program may or may not be configured so that all processing is performed only by the CPU on the control board.
