- the acid gas 3 is used for supplying the acid gas to the fuel cell main body.
- Ogas 33 has acid ogas 32 downstream of 27 described above, and this ogas 32 is connected to 25 described above. However, dilution 25 Ogas 32 may be omitted.
- the 002 4 controls the 234 24 244 246 23 232 339, the hydrogen pump 2 and the pump 3 5 etc., respectively, in response to the temperature sensor 4 and the temperature sensor 4 installed at the above-mentioned fixed locations. Furthermore, the control 4 is the electromagnetic 5 5 described later. Controls are omitted to make the surface easier to see.
- the supplied hydrogen gas is consumed as an electric reaction in the fuel cell and is then emitted as hydrogen gas.
- the released hydrogen gas passes through 23, is dewatered at 22, is returned to fuel gas 2 through the hydrogen pump 2, and is supplied again to the main body of the fuel cell. Since a 242 is provided between the hydrogen gas 2 2 3 and the hydrogen pump 2, the hydrogen gas does not flow backwards. Normally, and 2 2 2 7 2 9 244 and 246 are closed, but when these are opened as needed, the
- the system for example, pumps, various types, humidification, and piping
- the system may be stopped before or after the system and the fuel gas 2 may be discharged with fuel gas or the like to discharge the residue.
- the hydrogen pump will continue to be powered by fuel. Since the flow comes from the pond body side, the operation will be repeated until the fuel cell body is dried and further the hydrogen pump is dried. In particular, it usually takes more time to remove the hydrogen pump than other parts. However, with this method, the rate of the hydrogen pump is bad, and it takes a considerable time to stop the system.
- the Ming method two paths are configured and the second floor operation is performed when the fuel cell system is stopped at low temperature.
- the fuel cell body is dried by draining water on the road that includes the fuel cell body, and then in the second floor work, the fuel cell body is not included. It is possible to operate the hydrogen pump 2 on the second road, so that the hydrogen pump can be removed efficiently.

- the work for the freeze prevention is judged.
- the constant temperature 4 is as follows, it is judged that the operation of fuel gas 2 is necessary in control 4, and the next step Proceed to.
- the stem is stopped without any special operation, since water is not released from control 4.
- the stem can be learned. It should be noted that some normal stems may have a built-in work on the second road before the stem as a normal dog. In such a system, if in step S the measured temperature 4 exceeds, then only on the path before the system is carried out.
- the electromagnetic 23 5 decompression 232 is closed (or confirmed closed) and the electromagnetic 234 4 is opened (or confirmed open). 6 is formed.
- the hydrogen pon 2 will also be turned on within 6 of. As a result, the water remaining in 6 including the fuel cell body is recovered by 22.
- Step 3 it is judged whether the quantity in the road is below the standard. If it is judged that the quantity exceeds the standard, the operation is continued on the first road. On the other hand, if it is determined that the residual amount has dropped below the standard, the process is completed on the first road and the process proceeds to step 4.
- Control 4 there are the following methods as a method to judge that the quantity of the road has become below the standard.
- step S4 the electromagnetic control 234 4 is closed and the electromagnetic control 5 5 is opened by the command of control 4 to form 6 of 2. Even on this road, fuel is turned on by the hydrogen pump 2.
- Step 5 it is judged that the residual amount in 6 of 2 is below the standard. If it is determined that the quantity exceeds the standard, the second option within 6 is continued. On the other hand, if it is judged that the residual amount is below the standard, the system in (2)-(6) is completed and the system is stopped. Also in this step, a method similar to the method of residual quantity in 6 mentioned above can be used.

In addition, it is connected between the hydrogen pon 2222 of Is 53 and 23 (C). In addition, even in the 004 system configuration where the electromagnetic 525 is arranged on the is 53, the
- the stem of the battery cell of the present invention is used only when the stem is stopped. For example, if the freezing battery system is stopped at a low temperature and there is a risk of freezing, the above-mentioned operation (2) can be performed as necessary. In this case, the gas from the high-pressure hydrogen tank 2 may be used instead of the fuel as if it were inside the two systems.
