  By the way, when the fuel cell housed in the module 3 is a solid oxide fuel cell that generates power at a high temperature, the high-temperature heat generated by the power generation of the module 3 is thermally diffused as radiant heat, and the module storage chamber 4 The temperature becomes high, and as a result, the temperature of the outer case 2 may become high. Therefore, it is preferable that the temperature of the outer case 2 can be prevented (suppressed) from becoming high.

For example, the ventilation fan 9 is connected to the exhaust pipe 10. It can also be provided in the middle.

  Further, a blower located outside the outer case 2 is prevented so that the temperature of air that is exhausted by the ventilation fan 9 and supplied to the blower 5 flows through the blower air intake pipe 11 located outside the outer case 2. A heat insulating material or the like can be provided on the outer periphery of the air intake pipe 11.

  FIG. 3 shows another example of the fuel cell according to the present invention, and shows a fuel cell device 21 in which the ventilation fan 9 is arranged outside the module housing chamber 4.

  In such a fuel cell device 21, for example, when the fuel cell housed in the module 3 is a solid oxide fuel cell that generates power at a high temperature, the high-temperature heat generated by the power generation of the module 3 is radiant heat. Due to thermal diffusion, the temperature in the module storage chamber 4 becomes very high.

  In this case, although depending on the type of the ventilation fan 9, when the ventilation fan 9 is provided in the exterior case 2 constituting the module housing chamber 4, there is a possibility that the ventilation fan 9 is deteriorated by heat or the deterioration speed is increased. is there.

  Therefore, in the fuel cell device 21 shown in FIG. 3, the ventilation fan 9 is disposed outside the module storage chamber 4 (in FIG. 3, the exterior case 2 constituting the auxiliary machine storage chamber 4) and exhausted by the ventilation fan 9. The ventilation fan connecting pipe 15 for constituting a part of the passage for guiding at least a part of the air to the blower 5 and for guiding the air of the module housing chamber 4 to the ventilation fan 9 is provided.

  As a result, the temperature of the air in the module storage chamber 4 decreases in the process of flowing through the ventilation fan connecting pipe 15, and the increase in the temperature of the ventilation fan 9 can be suppressed, and the life of the ventilation fan 9 can be extended. Can do.

  In FIG. 3, blower air for guiding a part of the air in the module storage chamber 4 exhausted from the ventilation fan 9 to the exhaust pipe 10 connected to the ventilation fan 9 to the blower 5 (intake by the blower 5). An intake pipe 11 is connected. That is, in FIG. 3, the passage that guides at least part of the air exhausted by the ventilation fan 9 to the blower 5 is formed by the ventilation fan connection pipe 15, the exhaust pipe 10, and the blower air intake pipe 11.

  Thereby, the life of the ventilation fan 9 can be extended, and a part of the warmed air in the module storage chamber 4 exhausted by the ventilation fan 9 can be supplied to the module 3 by the blower 5. And it can suppress that the temperature in the module 3 falls, and the power generation efficiency of the module 3 can be improved.

  Further, a blower located outside the outer case 2 is prevented so that the temperature of air that is exhausted by the ventilation fan 9 and supplied to the blower 5 flows through the blower air intake pipe 11 located outside the outer case 2. A heat insulating material or the like can be provided on the outer periphery of the air intake pipe 11.

  FIG. 4 is another example of the fuel cell according to the present invention, and a part of a passage for guiding at least a part of air ventilated by the ventilation fan 9 to the blower 5 between the ventilation fan connecting pipe 15 and the blower 5. The fuel cell apparatus 31 which has connected the blower air intake pipe 11 which comprises is shown.

  In such a fuel cell device 31, the air in the module storage chamber 4 is exhausted through the ventilation fan connecting pipe 15, but a part of the exhausted air is in the middle of the ventilation fan connecting pipe 15. A blower air intake pipe 11 is connected so as to be sucked by the blower 5. That is, in FIG. 4, the passage for guiding at least a part of the air exhausted by the ventilation fan 9 to the blower 5 is formed by the ventilation fan connecting pipe 15 and the blower air intake pipe 11.

  Thereby, the blower air intake pipe 11 can be accommodated in the exterior case 2, and the fuel cell device 31 can be reduced in size. In this case, the exhaust pipe 10 may be unnecessary depending on the location of the fuel cell device 31 and the performance of the ventilation fan 9.

  For example, the blower air intake pipe 11 may be connected so as to protrude into the flow path of the ventilation fan connection pipe 15 so that the air flowing through the ventilation fan connection pipe 15 is efficiently sucked by the blower 5. In that case, the tip of the blower air intake pipe 11 is bent so as to be parallel to the direction of the flow path, so that the air that circulates through the ventilation fan connecting pipe 15 more effectively can be efficiently blown. 11 can be circulated and inhaled by the blower 5.

  FIG. 5 shows another example of the fuel cell according to the present invention, in which the partition portion 7 includes a hollow portion that constitutes a part of a passage that guides at least a portion of the air exhausted by the ventilation fan 9 to the blower 5. A fuel cell device 41 that is configured by a plate 7 and that communicates between the module storage chamber 4 and the cavity of the partition plate 7 and the ventilation fan connecting pipe 15 communicates with the cavity of the partition plate 7. It is.

  In such a fuel cell device 41, the air in the module storage chamber 4 is warmed by the radiant heat generated by the power generation of the module 3, and the partition plate 7 is also warmed by the radiant heat from the bottom surface of the module 3. Therefore, when the partition plate 7 is a plate having a hollow portion, the air in the hollow portion is also warmed.

  Here, by adopting a configuration in which the module storage chamber 4 and the cavity of the partition plate 7 communicate with each other, the warmed air in the module storage chamber 4 is separated from the module storage chamber communication portion 16 provided in the partition plate 7. In the process of flowing into the cavity portion 7 and flowing through the cavity portion of the partition plate 7, it is further warmed.

  And the ventilation fan connection pipe | tube 15 is connected with the partition plate 7 (the lower surface) so that it may connect with the cavity part of the partition plate 7. FIG. Therefore, the air warmed through the hollow portion of the partition plate 7 flows into the ventilation fan connection pipe 15 from the ventilation fan connection pipe communication portion 17, and flows through the ventilation fan connection pipe 15 to be ventilated by the ventilation fan 9. Is done.

  Further, a blower air intake pipe 11 is connected in the middle of the ventilation fan connection pipe 15 so that a part of the exhausted air is sucked by the blower 5. The air is taken in by 5 and supplied to the module 3.

  That is, the passage for guiding at least a part of the air exhausted by the ventilation fan 9 to the blower 5 in FIG. 5 is the module housing chamber communication part 16, the cavity of the partition plate 7, the ventilation fan connection pipe communication part 17, the ventilation fan. The connecting pipe 15 and the blower air intake pipe 11 are formed.

  And since this further warmed air is supplied to the module 3, it can suppress that the temperature in the module 3 falls, and the power generation efficiency of the module 3 can be improved.

  In addition, since the warmed air is exhausted through the cavity of the partition plate 7, the temperature of the partition plate 7 can be lowered, and the radiant heat generated by the power generation of the module 3 is generated in the auxiliary equipment storage chamber. It is possible to suppress the heat transfer to 6 and to prevent a failure due to the heat of the auxiliary machine.

  As described above, the blower air intake pipe 11 may be connected so as to protrude into the flow path of the ventilation fan connection pipe 15, and in that case, the tip of the blower air intake pipe 11 is connected to the flow path. It can also be bent so as to be parallel to the direction.

  FIG. 6 shows another example of the fuel cell according to the present invention, and shows a fuel cell device 51 that adjusts the temperature of the air taken in by the blower 5 and supplies it to the module 3.

  In order for the module 3 to generate power efficiently, warm air in the module storage chamber 4 and warm air flowing through the cavity of the partition plate 7 are sucked by the blower 5 and then supplied into the module 3. However, when the warmed air is at a high temperature of, for example, 50 ° C. to 70 ° C., the durability of the blower 5 may be adversely affected and the life of the blower 5 may be shortened. Therefore, although it depends on the type of the blower 5, after the warmed air is adjusted to a predetermined temperature (temperature lower than 50 ° C. to 70 ° C.), the blower 5 sucks and supplies the air into the module 3. It is preferable to do.

  Therefore, in the fuel cell device 51, an air flow rate adjusting means 19 is connected in the middle of a passage that leads a part of the air exhausted by the ventilation fan 9 to the blower 5, and the air flow rate adjusting means 19 is adjusted. The control device 12 performs control so that the temperature of the air taken in by the blower 5 becomes a predetermined temperature set in advance.

  Specifically, in FIG. 6, the temperature of the air sucked through the blower air intake pipe 11 is measured by the temperature sensor 20, and the measured temperature information is transmitted to the control device 12. When the transmitted temperature information exceeds a predetermined temperature set in advance, the control device 12 instructs the air adjustment means 19 so that the temperature information measured by the temperature sensor 20 becomes a predetermined temperature. A signal for adjusting the amount of air taken in through the air intake pipe 11 and the amount of air taken in through the auxiliary equipment storage chamber air intake pipe 18 is transmitted.

  Thereby, since the temperature of the air supplied to the module 3 by the blower 5 can be made lower than the temperature that adversely affects the blower 5, the durability of the blower 5 can be improved, and a predetermined By supplying the temperature air to the module 3, the power generation efficiency of the module 3 can be improved. An air flow rate adjusting valve or the like can be used as the air flow rate adjusting means 19.

  As described above, in FIG. 6, the passage for guiding at least a part of the air exhausted by the ventilation fan 9 to the blower 5 is the module storage chamber communication portion 16, the cavity of the partition plate 7, and the ventilation fan connection pipe communication. The unit 17, the ventilation fan connecting pipe 15, the blower air intake pipe 11 and the air flow rate adjusting means 19 are formed.

  Although the present invention has been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications and improvements can be made without departing from the scope of the present invention.

  For example, in the present invention, when the ventilation fan 9 is provided outside the module storage chamber 4, for example, in the exterior case 2 constituting the auxiliary device storage chamber 6, in order to suppress an increase in the temperature of the auxiliary device storage chamber 6, It is also possible to provide a second ventilation fan for ventilating the air inside the auxiliary machine storage chamber 6.
