However, in the fuel cell device 27 in which the module storage chamber 30 and the auxiliary machine storage chamber 31 are vertically divided as described above, at least one of the water supply pipes 16 that connect the water pump 5 and the reformer 4. Since the section is arranged in the module storage chamber 30, if the operation of the heating means is controlled based only on the temperature in one storage chamber, the water supply pipe 16 or the reforming water generation means W may not be frozen. There was a risk that efficient operation would be difficult.

  In particular, when the operation of the fuel cell device 27 is stopped, the temperature in the module storage chamber 30 may be lower than the temperature in the auxiliary machinery storage chamber 31, and the operation of these heating means is performed in the auxiliary machinery storage chamber 31. When the control is based only on the temperature, there is a risk of freezing particularly in a portion of the water supply pipe 16 located in the module storage chamber 30. Further, if the water pump 5 is forcibly operated while the water supply pipe 16 is frozen, there is a possibility that the water pump 5 may be abnormal or the fuel cell device 27 may be stopped.

  That is, the operation of the first heating means 17 provided in the water supply pipe 16 is controlled based on the temperature in the module storage chamber 30 measured by the module storage room temperature measuring means 33, and the auxiliary machine storage room temperature measurement. Based on the temperature in the auxiliary equipment storage chamber 31 measured by the means 34, the operation of the second heating means 18 provided in the reforming water generating means W is controlled.

  Specifically, the control device 9 performs the operation of the first heating unit 17 when the temperature in the module storage chamber 30 measured by the module storage chamber temperature measuring unit 33 becomes equal to or lower than the first predetermined temperature. When the temperature in the module storage chamber 30 measured by the module storage chamber temperature measuring unit 33 reaches a second predetermined temperature set higher than the first predetermined temperature, the first heating unit is started. It is preferable to control to stop the operation of 17.

  Thereby, when the temperature in the module storage chamber 30 becomes below the first predetermined temperature, the control device 9 performs control so as to start the operation of the first heating means 17, Freezing of the water supply pipe 16 connected to the reformer 4 can be efficiently suppressed, and the temperature in the module storage chamber 30 is set to a second predetermined temperature set higher than the first predetermined temperature.

An example in which the means 33 is arranged adjacent to the water supply pipe 16 is shown.

  In particular, when the operation is stopped, the temperature in the module storage chamber 30 is lower than that in the auxiliary machine storage chamber 31, so that the first heating means 17 is at least partially located in the module storage chamber 30. In particular, as shown in FIG. 3, it is preferable to dispose the water supply pipe 16 so as to cover the entire portion located in the module storage chamber 30.

  The first heating means 17 is arranged so that at least a part of the first heating means 17 is located in the module storage chamber 30, and the operation of the first heating means 17 is measured by the module storage room temperature measuring means 33. By controlling based on the temperature in 30, the freezing of the water supply pipe 16 can be efficiently suppressed.

  Further, the control device 9 starts the operation of the second heating means 18 when the temperature in the auxiliary equipment storage chamber 31 measured by the auxiliary equipment storage room temperature measuring means 34 becomes equal to or lower than the third predetermined temperature. The second heating is performed when the temperature in the auxiliary machine storage chamber 31 measured by the auxiliary machine storage room temperature measuring means 34 reaches the fourth predetermined temperature set higher than the third predetermined temperature. It is preferable to control to stop the operation of the means 18.

  As a result, the control device 9 performs control so that the operation of the second heating means 18 is started when the temperature in the auxiliary machine storage chamber 31 becomes equal to or lower than the third predetermined temperature. The freezing of the generation means W can be efficiently suppressed, and when the temperature in the auxiliary machine storage chamber 31 reaches the fourth predetermined temperature set higher than the third predetermined temperature, the second By stopping the operation of the heating means 18, it is possible to suppress a decrease in power generation efficiency.

  Here, the third predetermined temperature is preferably a temperature at which freezing of the reforming water generating means W can be efficiently suppressed, and a temperature at which the second heating means 18 can be operated efficiently, For example, it can be set to the same temperature as the first predetermined temperature for efficiently operating the first heating means 17 (set appropriately between 0 ° C. and 5 ° C.).

  On the other hand, the fourth predetermined temperature is preferably set higher than the third predetermined temperature, and is preferably set to a temperature at which the reforming water generating unit W is unlikely to freeze, and the first heating unit 17 operates efficiently. It can be set to the same temperature as the second predetermined temperature (set appropriately between 7 ° C. and 10 ° C.).

  In this case, the auxiliary equipment storage room temperature measuring means 34 is a part of the auxiliary equipment storage room 34 where the temperature is lower (for example, the auxiliary equipment storage room) in order to efficiently suppress freezing of the reforming water generating means W. 34 is preferably arranged on the bottom side (ground side) or outside air intake side in 34 (in FIG. 3, the auxiliary equipment storage room temperature measuring means 34 is adjacent to the condensed water supply pipe 14 on the bottom side.
