化する問題があった。In conventional fuel cell generators, an inert gas such as nitrogen is supplied to the fuel supply system at startup and shutdown, and the reforming reaction occurs after cleaning out any remaining fuel in the system. It was started and then shut down after purging out the fuel. This means that if air is mixed into the fuel remaining in the system for some reason and generates explosion air, this explosion air may reach the reformer burner or escape from the reaction tube. Since there is a risk of an explosion if the burner leaks, a method is used in which the residual gas is wiped out with nitrogen before the burner is ignited or the operation is stopped. 4' However, such equipment requires the installation of a new protective gas storage and its supply system, and when the generator is used as a mobile or portable power source, the equipment becomes large.

Furthermore, steam can be easily generated using the temperature of the reformer, and existing equipment can be used as is. In other words, fuel reformers for fuel cells generally use a steam reforming method, and for example, the fuel is natural gas (CHI).

を設ける必要がないという特長を有する。FIG. 1 shows an embodiment of the present invention in which a methanol reformer 7 and a phosphoric acid fuel cell tank 2 are combined. A reaction occurs in which methanol and water necessary for the reforming shown in equation (2) in the previous section are passed through the methanol reformer 7 through the pulp 6 from the methanol tank 1 and water tank 2 by the methanol pump 4 and water pump 5, respectively. The reaction tube 9 supplied to the tube 9 is constructed by directly connecting an evaporation tube for a mixture of methanol and water and a reforming tube in series, and the reforming tube is filled with a methanol reforming catalyst (Cu-Zn system). has been done. The temperature inside the reforming tube is maintained at about 250° C., and the fuel reformed into 008 and H8 according to the reaction of equation (2) in the previous section is supplied to the fuel cell stack 12 via the pulp 11. The temperature of the fuel cell stack is maintained at approximately 190° C., and reaction air is supplied to it from an air blower 14, so that a DC output is obtained from the output terminal 5 in accordance with a known electromotive reaction. In addition to direct current output, a fuel cell stack generates heat due to reaction resistance (polarization) and its internal electrical resistance, so a cooling system (air cooling or water cooling) is required to maintain the temperature at approximately 190°C according to a method not shown.
is included. In the fuel cell stack 12, after approximately 80% of the supplied hydrogen is consumed by an electromotive reaction, the remaining hydrogen-containing gas is supplied to the burner 8 via the pulp 13.
To start up such a fuel cell power generation device, first, methanol and air are supplied to the burner 8 using the methanol pump 3 and the air blower 10, respectively, and the methanol is combusted, so that the methanol reformer 7 is heated to a predetermined temperature ( 25
0°C). At the same time, the waste heat of the reformer 7 is supplied to the fuel cell stack 12 via the heating pipe 17 and the pulp 18 to maintain the stack 12 at a predetermined temperature (approximately 190℃).
℃). At this time, it is important that the temperature of the stack 12 be higher than the temperature at which the water scum does not contract under the pressure within the fuel supply system. After heating the stack 12, water is supplied from the water pump 5 to the reaction tube 9 via the pulp 6.The reaction tube 9 is heated to a temperature of 100°C or more by the burner 8, so it becomes water vapor, which causes the pulp 11 to The water vapor is then supplied into the fuel cell stack 12 and replaces the fuel passage within the fuel cell stack 12 with water vapor. The water vapor leaving the fuel cell stack 12 is discharged to the outside through the pulp 16. By replacing the inside of the fuel supply system with water and air in this way, the fuel remaining in the system can be removed. After that, the methanol pump 4 is started to perform a methanol reforming reaction in the reformer 7, and the reformed fuel is supplied to the fuel cell stack, and while an electromotive reaction is started, the methanol reformer 7 and the fuel cell The temperature of the stack 12 is increased to a predetermined temperature. At this time, since the valve 16 is closed and the valve 13 is open after the reforming reaction is started, the exhaust gas from the fuel cell stack 12 is combusted by the burner 8 via the valve 13. The temperature of the reformer 7 is adjusted by the fuel supplied to the burner and the amount of air from the air blower 10, and if the exhaust fuel supplied from the valve 13 is insufficient, methanol is supplied from the pump 3. Furthermore, when the temperature of the fuel cell stack is lower than a predetermined temperature, it is necessary to raise the temperature using the exhaust gas from the methanol reformer 7.
Since a fuel cell stack generally generates heat, it is cooled down by a known cooling device once it reaches a predetermined temperature. Next, when the power generator is stopped, the methanol pump 4
The methanol reformer 7 is stopped and only water is supplied to the methanol reformer 7 to generate water vapor, and the inside of the fuel passages in the methanol reformer 7 and the fuel cell stack 12 are replaced with water vapor. The temperature of the methanol reformer 7 and the fuel cell stack 12 is set to about 1
After lowering the temperature to below 50°C, stop all pumps and close valves 6.11.13. As a result, the reaction tube 9 in the methanol reformer is in a sealed state, preventing air from entering the tube. Most reformed! When the temperature of the reactor drops, the pressure inside the reaction tube becomes reduced, and if there is a leak in a valve, etc., air will get mixed into the reaction tube, but if the amount of leak is small, it will not harm the reforming performance. In the case of restart, the water remaining in the reaction tube is vaporized again by heating, and the pressure returns to near the original state when steam replacement starts at startup, so there is no problem with pressure balance.On the other hand, the temperature of the fuel cell stack 12 is low. As the temperature decreases, the volume of water vapor decreases, and when the temperature drops below 100°C, it condenses, reducing the pressure in the fuel passage. Therefore, the valve 16 is opened to introduce air into the stack by the amount of reduced pressure. Since the fuel in the stack has already been replaced by water vapor,
Even if air is introduced, the fuel electrode in the stack will not be damaged. Furthermore, the water vapor introduced into the stack will be absorbed by the phosphoric acid electrolyte, promoting volume expansion of the electrolyte or wetting of the electrode, and the stack 12 However, in this case, the temperature of the stack 12 is 10
When the temperature is 0°C or higher, the blower 14 blows the reaction air into the stack 1.
This can be prevented by introducing water vapor into the solute and evaporating it into the reaction air side. It has the advantage that there is no need to provide

This not only eliminates the need for protective gas storage and supply systems (
Since the power generating device can be made smaller and lighter, it is particularly suitable when the power generating device is used as a mobile or portable power source.
