Regarding the height of the equipment, it is of course necessary to consider the basic conditions such as the behavior of the reaction gas flow inside the fuel cell stack, the cooling performance of the fuel cell stack, the earthquake resistance of the fuel cell stack, and the conditions of the installation site. It is necessary to keep in mind the route and means of delivery to the installation site.

う問題点がある。FIG. 4 is a perspective view showing the basic structure of a phosphoric acid fuel cell. As shown in the figure, a fuel cell stack 1 is formed into a rectangular parallelepiped by stacking rectangular flat-shaped unit cells 2, and has a fuel supply manifold 3 and a fuel discharge manifold 4 on its four side surfaces. The air supply manifold 5 and the air discharge manifold 6 are installed opposite to each other, and fuel and air are supplied to generate electricity. In this configuration, the fuel supplied from the fuel supply manifold 3 flows while being distributed to the fuel flow grooves 7 formed in the plurality of stacked unit cells 2, and similarly supplied from the air supply manifold 5. Air is a plurality of single cells 2
The air will be distributed to the air flow grooves 8 formed in the flow path. Therefore, if the height of the fuel cell stack 1 is too high, the flow rate of fuel or air flowing between the unit cells 2 in the central portion and the unit cells 2 in the upper layer portion and the lower layer portion becomes different, and the fuel cells do not flow evenly. Performance cannot be obtained. Therefore, in the conventional phosphoric acid fuel cell, when the distribution height, that is, the height of the manifold exceeds 1.5 m, the fuel cell stack is divided into upper and lower blocks, and the manifold is provided in each of the blocks. The method of evenly flowing fuel and air into the unit cell is adopted. However, if the fuel cell stack is divided into two blocks in this way, the manifold and its accompanying components are doubled, resulting in higher cost. There is a problem that it ends up.

の高さを所定値以上とすることが必須条件となる。Further, as the height of the fuel cell stack 1 becomes higher, the seismic resistance becomes worse, so that it is necessary to incorporate a structural member for supporting during transportation, which is disadvantageous in terms of cost. On the other hand, in order to secure the cooling performance of the fuel cell stack, the height of the device needs to be equal to or higher than a predetermined height. FIG. 5 is a system diagram showing a basic configuration of a general cooling system of a phosphoric acid fuel cell. In the figure, the fuel cell main body 11 is schematically shown, and a cooling plate 12 provided with a cooling pipe is arranged every time a plurality of unit cells (not shown) are stacked, and cooling water is supplied to the cooling pipe. The fuel cell main body 11 is cooled by flowing it and is kept at a constant temperature. As this cooling water, water sucked by the cooling water circulation pump 14 from the liquid phase portion of the water vapor separator 13 is used, and the water that cools the fuel cell main body 11 and is partially heated to steam is used. The two-phase flow with steam is again steam separator 1
It is returned to the vapor phase part of 3. In addition, this steam separator 13
In this case, the thermal balance is maintained by supplying the steam for reforming the fuel to the reformer 16 and discharging the steam to the external heat recovery facility 15 to receive the condensed water. As described above, the steam separator 13 is used for cooling the fuel cell main body 11.
Since the water sucked by the cooling water circulation pump 14 from the liquid phase part of is used, the effective NPSH (Net Positive Suc
It is necessary to select the height of the water level of the steam separator 13 so that the heat head exceeds the required NPSH of the cooling water circulation pump 14. If the effective NPSH falls below the required NPSH, the cooling water circulation pump 14 causes cavitation and is damaged. Fuel cell main body 11
May cause overheating. That is, in order to ensure the cooling performance of the fuel cell main body 11, the water level of the steam separator 13 is high, and accordingly, the steam separator 1
It is an indispensable condition that the height of the package type fuel cell power generation device accommodating 3 as one is set to a predetermined value or more.

を提供することを目的とする。Further, the packaged fuel cell power generator is often installed inside a building. For example, when it is installed in a basement, it passes through a carry-in door from a dry area,
It is generally carried into a machine room or a power room. Therefore, the packaged fuel cell power generator needs to be sized so that it can be carried in through this carrying-in route. The present invention has been made in consideration of the above problems, and has high reaction gas flow performance and structural reliability of the fuel cell main body, and at the same time, high cooling performance reliability. An object of the present invention is to provide a packaged fuel cell power generator that can be easily installed in a building.

ましい。As already described with reference to FIG. 4, in the fuel cell stack, the fuel supplied from the fuel supply manifold 3 and the air supplied from the air supply manifold 5 are stored in the plurality of stacked unit cells 2. Since a method of distributing and flowing the fuel to the fuel flow groove 7 and the air flow groove 8 is adopted, if the height of the fuel cell stack 1 is too high, the unit cell 2 in the central portion and the unit cells 2 in the upper and lower layers are provided. There is a difference in the flow rate of fuel and air flowing in, and the flow does not flow evenly. In the conventional fuel cell stack, when the distribution height exceeds 1.5 m, it is divided into two upper and lower blocks, but if it is divided into two blocks, the manifold and its accompanying parts However, the height of the fuel cell stack should be kept below 2.3 m, and therefore the height of the fuel cell stack should be kept below 2.3 m.

相対的に安価となる。Therefore, if the height of the package type fuel cell power generator is set to 2.0 m or more and 2.8 m or less as described above, the height of the mount for mounting the fuel cell stack is 0.2 m and the height is The height of the fuel cell stack is 2.3m, with the required height of the piping and exhaust duct to be set to 0.3m.
Therefore, the fuel cell stack has sufficient reaction gas flow performance even if it is constructed as an integral unit, and since it is not divided, the number of required parts is small and the cost is relatively low.

ており、本方式においては、燃料電池本体の冷却を確実
に行うには、系の有効ＮＰＳＨが冷却水循環ポンプの所
要ＮＰＳＨ以上となるよう設定する必要がある。When the height of the package type fuel cell power generator is selected as described above, not only the height is lowered, but also the fuel cell stack is formed integrally, so that the structure has excellent earthquake resistance, The supporting member added even during transportation becomes simple and inexpensive. On the other hand, in this type of fuel cell power generator, as already described with reference to FIG. 5, a method is used in which saturated water of the steam separator is sucked by a cooling water circulation pump and sent to the fuel cell main body to cool. In this method, in order to reliably cool the fuel cell body, it is necessary to set the effective NPSH of the system to be equal to or higher than the required NPSH of the cooling water circulation pump.

1.8〔ｍ〕以上となる。The effective NPSH is calculated from the water level height H [m] of the steam separator, the installation height of the pump, that is, the height h 1 [m] from the bottom of the device around the pump shaft, and the distance between the steam separator and the pump. It is represented by (H−h 1 −h 2 ) [m] obtained by subtracting the water head h 2 [m] corresponding to the flow path resistance. In normal equipment, h 1 is
About 0.3 [m], h 2 is 0.15 even if the flow path is thick and short
It becomes about [m]. Moreover, the required NPSH of the cooling water circulation pump usually used is at least 1 [m] or more. Therefore, the water level height H of the water vapor separator needs to be set to 1.45 [m] or more from the bottom of the device. The steam separator must have a sufficient vapor phase space at the top to smoothly discharge steam, so if this height is taken into consideration, the height from the bottom of the device at the top of the steam separator will be
It becomes 1.8 [m] or more.

向上する。Therefore, if the height of the packaged fuel cell power generator is set to 2.0 m or more and 2.8 m or less as described above, even if the space of the valve and the pipe arranged at the top is taken into consideration, Since the height of the top of the separator from the lowermost part of the device can be 1.8 [m] or more, the fuel cell main body can be reliably cooled. Next, in the existing telecommunications buildings that are supposed to be installed with packaged fuel cell power generators, they are often installed in the basement, and they are transported from the dry area through the entrance door to the machinery room or power room. Is common. From over 2000 telecommunications buildings nationwide, contract electric power of 600 kW or more and existing in the Tokyo metropolitan area were extracted, and according to the result of the investigation of the carry-in condition, the width is 3.0 m and the height is 3.5 m. In this device, the carry-on rate is limited to about 50% due to the restrictions on the size and shape of the dry area. This value is calculated assuming that the carry-in door has a margin of 0.2 m in width and height, taking into account the space for the gantry and spacers for carry-in. On the other hand, considering the carry-in ratio when the width is the same and only the height is changed, it is 70% when the height is 3.1 m, and it significantly improves to 85% when the height is 2.7 m. .

If the height is set to 2.5m or less, not only the loading door but also other restrictions on the loading path will be relaxed, and the loading rate will dramatically increase, and loading and installation in almost all telecommunications buildings will be possible. Is expected to be possible.

This device is a packaged fuel cell power generator with an output of 100 kW, and the height of the device consisting of the power generator main body 21A and the ventilation hood 22 above it is displayed with a width of 2.0 to 2.8 m. Is increased, and the number of stacked unit cells of the fuel cell stack required to obtain a predetermined output is correspondingly reduced to lower the height of the fuel cell stack.

Even if it is configured as, it will have sufficient reaction gas flow performance. Further, since it is not divided, the number of required parts is small and the cost is relatively low. In addition, the water level of the steam separator in the cooling system, which sucks saturated water from the steam separator by the cooling water circulation pump and sends it to the fuel cell body, should be set at least 1.45 [m] from the bottom of the device. Therefore, the effective NPSH of the system surely exceeds the required NPSH of the cooling water circulation pump, and the fuel cell main body is reliably cooled, so that the package fuel cell power generator with high reliability is obtained.

A detachable ventilation hood 22A with a height of 0.5 m is provided on the upper part of the power generator main body 21B of 2.5 m. The packaged fuel cell power generator of the present embodiment is not only a highly reliable device having sufficient reaction gas flow performance and cooling performance as in the device of the first embodiment described above, but also removable ventilation.
