Description

この発明は、燃料電池本体、燃料改質系機器、燃料電池本体用の冷却水系機器等を同一のパッケージに収納して構成される燃料電池発電装置、特に冬期の発電運転休止時に危惧される冷却水系機器の水の凍結を防止した燃料電池発電装置に関する。   The present invention relates to a fuel cell power generation device configured by housing a fuel cell main body, a fuel reforming device, a cooling water system device for the fuel cell main body, etc. in the same package, in particular, a cooling water system which is a concern when power generation operation is suspended in winter. The present invention relates to a fuel cell power generation apparatus that prevents freezing of equipment water.

パッケージ型の燃料電池発電装置においては、燃料電池本体や燃料改質系機器、さらには燃料電池本体用の冷却水系機器等の主要な構成機器が同一のパッケージに収納され、屋外に据え付けられて運転される。発電運転時には燃料電池本体や燃料改質系機器からの放熱があるので、仮に外気の温度が氷点下に下がっても燃料電池本体用の冷却水系機器の水の凍結は容易に回避されるが、発電運転休止時にはこれらの機器からの放熱がないため、水が凍結して冷却水系機器が破損し、燃料電池発電装置の発電運転が不能になる危険性がある。
図５は、従来のこの種の燃料電池発電装置の基本構成を示す断面図である。本図において、１はパッケージ、２はパッケージ１に配された吸気口、３はパッケージ１内に組込まれた換気ファン、４は排気部である。また、５は、パッケージ１の内部を加温するための発熱器であり、２０は、換気ファン３と発熱器５を制御するための制御装置である。本構成の燃料電池発電装置では、水の凍結が危惧される冬期の発電運転停止時には、換気ファン３の駆動量と発熱器５の発熱量を制御装置２０によって制御することにより、パッケージ１の内部を加温して冷却水系機器の水の凍結を防止している。 In the package type fuel cell power generator, the main components such as the fuel cell main body, fuel reforming equipment, and cooling water system equipment for the fuel cell main body are housed in the same package and installed outdoors. Is done. During power generation operation, heat is dissipated from the fuel cell body and fuel reforming equipment, so that even if the outside air temperature falls below freezing point, freezing of water in the cooling water system equipment for the fuel cell body can be easily avoided. Since there is no heat radiation from these devices when the operation is stopped, there is a risk that water freezes and the cooling water system device is damaged, and the power generation operation of the fuel cell power generation device becomes impossible.
FIG. 5 is a cross-sectional view showing the basic configuration of this type of conventional fuel cell power generator. In this figure, 1 is a package, 2 is an intake port disposed in the package 1, 3 is a ventilation fan incorporated in the package 1, and 4 is an exhaust section. Reference numeral 5 denotes a heat generator for heating the inside of the package 1, and reference numeral 20 denotes a control device for controlling the ventilation fan 3 and the heat generator 5. In the fuel cell power generation device of this configuration, when the power generation operation is stopped in winter when there is a risk of freezing of water, the driving amount of the ventilation fan 3 and the heat generation amount of the heat generator 5 are controlled by the control device 20 to control the inside of the package 1. Heating prevents the water in the cooling water system from freezing.

上記のように、屋外に据え付けて使用されるパッケージ型の燃料電池発電装置においては、冬期の発電運転停止時に冷却水系機器の凍結を生じないように種々の方策が採られている。しかしながら、例えば図５に示した例では、換気空気により加温される部分が発熱器５の近傍と換気空気が流れる特定方向に限定されるので、パッケージ内に分散する各種の冷却水系機器の凍結防止策としては必ずしも十分でないという難点があり、また、特許文献１や特許文献２に示された方法を適用すると、付帯設備が大きくなり、コストが高くなるという問題点がある。
本発明は上記の従来技術の現状を顧慮してなされたもので、本発明の目的は、低温環境下にあっても、燃料電池本体を冷却する冷却水系機器の水の凍結が確実に、かつ安価に防止される燃料電池発電装置を提供することにある。 As described above, in a package type fuel cell power generator installed and used outdoors, various measures are taken so that the cooling water system equipment does not freeze when the power generation operation is stopped in winter. However, in the example shown in FIG. 5, for example, the portion heated by the ventilation air is limited to the vicinity of the heat generator 5 and the specific direction in which the ventilation air flows, so that the various cooling water system devices dispersed in the package are frozen. As a preventive measure, there is a problem that it is not always sufficient, and when the methods shown in Patent Document 1 and Patent Document 2 are applied, there is a problem that incidental facilities become large and cost increases.
The present invention has been made in consideration of the current state of the prior art described above, and the object of the present invention is to ensure that the water in the cooling water system equipment for cooling the fuel cell body is frozen even in a low temperature environment, and An object of the present invention is to provide a fuel cell power generator that can be prevented at low cost.

上記の目的を達成するために、本発明においては、
燃料電池本体、燃料改質機器、燃料電池本体を冷却する冷却系機器、発熱器及び換気ファンをパッケージ内に備え、上記の換気ファンにより上記のパッケージ内の空気を排気口から排出して換気を行う燃料電池発電装置において、
（１）発電運転停止時に、上記の発熱器で昇温された空気を空気循環手段によりパッケージ内部に循環させてパッケージ内の水の凍結を防止することとする。
（２）さらに、上記の（１）の燃料電池発電装置において、上記の空気循環手段を、正逆回転可能な換気ファンと上記の排気口に備えられた開閉扉とから構成し、発電運転停止時に、上記の開閉扉を閉鎖し、上記の換気ファンを逆回転運転させることにより、上記の発熱器で昇温された空気をパッケージ内部に循環させてパッケージ内の水の凍結を防止することとする。 In order to achieve the above object, in the present invention,
A fuel cell body, a fuel reforming device, a cooling system device for cooling the fuel cell body, a heat generator, and a ventilation fan are provided in the package, and the air in the package is exhausted from the exhaust port by the above ventilation fan for ventilation. In the fuel cell power generator to perform,
(1) When the power generation operation is stopped, the air heated by the heat generator is circulated inside the package by the air circulation means to prevent water in the package from being frozen.
(2) Further, in the fuel cell power generator of the above (1), the air circulation means is composed of a ventilation fan capable of rotating in the forward and reverse directions and an open / close door provided in the exhaust port, and the power generation operation is stopped. Occasionally, the door is closed and the ventilation fan is operated in reverse to circulate the air heated by the heat generator inside the package to prevent freezing of water in the package; To do.

（３）また、上記の（１）の燃料電池発電装置において、上記の空気循環手段を、上記の換気ファンと、排気口に設けられた開閉扉と、開閉扉が閉状態のときに上記の換気ファンからの送風をパッケージ下部へ導く導風管とから構成し、発電運転停止時に、上記の開閉扉を閉じるとともに、発熱器で昇温された空気を上記の換気ファンによりパッケージ内部に循環させてパッケージ内の水の凍結を防止することとする。
（４）さらにまた、上記の（２）または（３）の燃料電池発電装置において、上記の発熱器で昇温された空気を上記の冷却系機器へと集中的に導く導風管を備えることとする。 (3) Further, in the fuel cell power generator of (1), the air circulation means may include the ventilation fan, an open / close door provided at an exhaust port, and the open / close door when the open / close door is closed. It consists of an air duct that guides air from the ventilation fan to the bottom of the package. When the power generation operation is stopped, the door is closed and air heated by the heat generator is circulated inside the package by the ventilation fan. To prevent water in the package from freezing.
(4) Furthermore, in the fuel cell power generator of the above (2) or (3), an air guide pipe that intensively guides the air heated by the heat generator to the cooling system device is provided. And

燃料電池本体や、燃料改質機器、燃料電池本体を冷却する冷却系機器、発熱器等を同一のパッケージの内部に収納して構成される燃料電池発電装置において、上記の（１）のように、発電運転停止時に、上記の発熱器で加温された空気を上記の空気循環手段によって上記のパッケージ内部に循環させることとすれば、燃料電池本体や燃料改質機器からの発熱のない発電運転停止時においても、パッケージ内部は加温された空気によって偏りなく加温されることとなるので、燃料電池本体を冷却する冷却系機器の凍結が効果的に防止される。
したがって、上記の（２）のように、空気循環手段を、正逆回転可能な換気ファンと排気部に備えられた開閉扉とから構成し、発電運転停止時に、開閉扉を閉鎖し、換気ファンを逆回転運転させて、発熱器で加温された空気をパッケージ内部に循環させることとすれば、冷却系機器の凍結が効果的に防止される。また、上記の（３）のように、空気循環手段を、換気ファンと、排気口に設けられた開閉扉と、開閉扉が閉状態のとき換気ファンからの送風を下部に導く導風管とから構成し、発電運転停止時に、開閉扉を閉じて、上記の発熱器で昇温された空気をパッケージ内部に循環させることとしても、冷却系機器の凍結が効果的に防止される。さらに上記の（４）のように、温められた空気を上記の冷却系機器へと集中的に導く導風管を備えれば、上記のごとき特に凍結防止に留意すべき機器を選択的に加温できるので、冷却系機器の凍結防止に特に有効である。 In a fuel cell power generator configured by housing a fuel cell main body, a fuel reforming device, a cooling system device for cooling the fuel cell main body, a heat generator and the like in the same package, as in (1) above When the power generation operation is stopped, if the air heated by the heat generator is circulated inside the package by the air circulation means, the power generation operation does not generate heat from the fuel cell main body or the fuel reforming device. Even when the package is stopped, the inside of the package is heated evenly by the heated air, so that freezing of the cooling system device for cooling the fuel cell main body is effectively prevented.
Therefore, as in (2) above, the air circulation means is composed of a ventilation fan that can rotate forward and backward and an opening / closing door provided in the exhaust part, and when the power generation operation is stopped, the opening / closing door is closed, and the ventilation fan If the air is heated in the reverse direction and the air heated by the heat generator is circulated inside the package, the cooling system equipment is effectively prevented from freezing. In addition, as described in (3) above, the air circulation means includes a ventilation fan, an opening / closing door provided at the exhaust port, and an air guide pipe that guides air from the ventilation fan to the lower part when the opening / closing door is closed. Even when the door is closed when the power generation operation is stopped and the air heated by the heat generator is circulated inside the package, the cooling system device is effectively prevented from freezing. Further, as described in (4) above, if an air guide pipe that concentrates the warmed air to the cooling system equipment is provided, the above-mentioned equipment that should be especially careful of freezing prevention is selectively added. Since it can be heated, it is particularly effective in preventing freezing of cooling system equipment.

本発明の最良の実施形態は、燃料電池本体、燃料改質機器、燃料電池本体を冷却する冷却系機器、発熱器及び換気ファンをパッケージ内に備え、上記の換気ファンにより上記のパッケージ内の空気を排気口から排出して換気を行う燃料電池発電装置において、発電運転停止時に、空気循環手段、例えば正逆回転可能な換気ファンと排気口に設けられた開閉扉とから構成される空気循環手段により、上記の発熱器で昇温された空気をパッケージ内部に循環させて、パッケージ内の水の凍結を防止するよう構成された燃料電池発電装置にある。   The best mode of the present invention includes a fuel cell body, a fuel reforming device, a cooling system device for cooling the fuel cell body, a heat generator and a ventilation fan in the package, and the air in the package is provided by the ventilation fan. In a fuel cell power generator that ventilates by exhausting air from the exhaust port, when the power generation operation is stopped, air circulation means, for example, a ventilation fan that can rotate forward and reverse, and an air circulation means that is configured by an open / close door provided at the exhaust port Thus, the fuel cell power generator configured to circulate the air heated by the above-described heat generator inside the package and prevent the water in the package from freezing.

図１は、本発明の燃料電池発電装置の第１の実施例の構成図で、凍結防止が行われる発電運転停止時の構成が示されている。本図は、従来例として示した図５の燃料電池発電装置の構成に対比して示されており、同一機能を有する構成部品には同一符号が付されている。本図の構成の特徴は、従来例の換気ファン３に替わって、正逆回転可能な換気ファン３Ａと排気部４に備えられた開閉扉６とからなる空気循環手段が配されていることにある。
本図の構成の燃料電池発電装置では、発電運転時には、開閉扉６を開放し、換気ファン３Ａを正方向に回転させることによって、換気空気が換気ファン３Ａの下側から上側へと送られ、開放された開閉扉６の開口部より外部へ排出される。これに対して発電運転停止時には、図示したように、パッケージ１の内部に備えられた発熱器５を作動させ、開閉扉６を閉鎖し、換気ファン３Ａを逆回転方向に回転させて使用される。開閉扉６の閉鎖によりパッケージ１の内部は閉空間となるので、換気空気は、図中に細矢線で示したように、中心部分を下方へと流れ、周辺部分を上方へと流れる循環流を形成することとなる。この間、換気空気の循環流は発熱器５で加熱され、温度が高くなる。したがって、パッケージ１の内部に備えられた冷却水系機器等の諸収納機器は加熱された換気空気の循環流により加温されるので、冷却水系機器の異常温度低下が防止され、冷却水の凍結が防止されることとなる。 FIG. 1 is a configuration diagram of a first embodiment of a fuel cell power generator according to the present invention, showing a configuration when a power generation operation is stopped to prevent freezing. This figure is shown in comparison with the configuration of the fuel cell power generation apparatus of FIG. 5 shown as a conventional example, and the same reference numerals are given to the components having the same functions. The feature of the configuration of this figure is that, instead of the ventilation fan 3 of the conventional example, an air circulation means comprising a ventilation fan 3A that can rotate forward and backward and an open / close door 6 provided in the exhaust part 4 is arranged. is there.
In the fuel cell power generation device having the configuration shown in the figure, during power generation operation, the door 6 is opened and the ventilation fan 3A is rotated in the forward direction, whereby ventilation air is sent from the lower side to the upper side of the ventilation fan 3A. It is discharged to the outside through the opening of the opened door 6. On the other hand, when the power generation operation is stopped, as shown in the figure, the heater 5 provided inside the package 1 is operated, the door 6 is closed, and the ventilation fan 3A is rotated in the reverse rotation direction. . Since the interior of the package 1 becomes a closed space by closing the door 6, the ventilation air flows in a circulating flow that flows downward in the central portion and upward in the peripheral portion, as indicated by thin arrows in the figure. Will be formed. During this time, the circulation flow of the ventilation air is heated by the heater 5 and the temperature rises. Accordingly, since various storage devices such as the cooling water system equipment provided in the package 1 are heated by the circulation flow of the heated ventilation air, an abnormal temperature drop of the cooling water system equipment is prevented, and freezing of the cooling water is prevented. Will be prevented.

図２は、本発明の燃料電池発電装置の第２の実施例の構成図で、図１と同様に、凍結防止が行われる発電運転停止時の構成が示されている。図２の構成の特徴は、図１の構成において特に凍結防止を図る必要性の高い凍結防止機器７に対して集中的に加温した換気空気を送る導風管８を設置したことにある。すなわち、本構成では、換気ファン３Ａの下側と凍結防止機器７との間に導風管８が配設されているので、発電運転停止時に換気ファン３Ａを逆回転方向に回転させて使用し、換気空気を換気ファン３Ａの上側から下側へと送れば、凍結防止機器７へは導風管８を通して集中的に加温された換気空気が送られるので、凍結防止機器７の凍結防止に特に効果的である。   FIG. 2 is a block diagram of a second embodiment of the fuel cell power generator according to the present invention, and shows the configuration when the power generation operation is stopped in the same manner as in FIG. The feature of the configuration of FIG. 2 is that an air guide tube 8 that sends intensively heated ventilation air to the anti-freezing device 7 that is particularly necessary to prevent freezing in the configuration of FIG. 1 is installed. That is, in this configuration, since the air guide tube 8 is disposed between the lower side of the ventilation fan 3A and the freeze prevention device 7, the ventilation fan 3A is rotated in the reverse rotation direction when the power generation operation is stopped. If the ventilation air is sent from the upper side to the lower side of the ventilation fan 3A, the ventilation air heated in a concentrated manner is sent to the anti-freezing device 7 through the air duct 8, so that the anti-freezing device 7 is prevented from freezing. It is particularly effective.

図３は、本発明の燃料電池発電装置の第３の実施例の構成図で、図１、図２と同様に、凍結防止が行われる発電運転停止時の構成が示されている。図３の構成の特徴は、換気ファン３と開閉扉９とから構成される空気循環手段を備え、発電運転時には開閉扉９を開状態として換気を排気口に導き、発電運転停止時には開閉扉９を閉状態として換気をパッケージ１の内部へと導いて運転させる構成としたことにある。すなわち、図３の構成では、パッケージ１の側面の内側に同心円状に導風管１０が配され、かつ、排気部４に、換気空気を排気口か、あるいはパッケージ１の内部の導風管１０の外周部へと導く開閉扉９が設置されており、開閉扉９を切換えて換気をパッケージ１の内部の導風管１０の外周部へと導くことにより換気空気が循環され、加熱されて、冷却水系機器の凍結が防止される。   FIG. 3 is a configuration diagram of a third embodiment of the fuel cell power generator according to the present invention, and shows a configuration at the time of power generation operation stop where freezing prevention is performed, similarly to FIGS. 1 and 2. 3 is provided with an air circulation means composed of a ventilation fan 3 and an opening / closing door 9, and opens and closes the opening / closing door 9 during power generation operation to guide ventilation to the exhaust port, and opens / closes the door 9 when power generation operation is stopped. In the closed state, ventilation is led to the inside of the package 1 for operation. That is, in the configuration of FIG. 3, the air guide tube 10 is concentrically arranged inside the side surface of the package 1, and ventilation air is exhausted to the exhaust unit 4 or the air guide tube 10 inside the package 1. Opening and closing doors 9 leading to the outer peripheral part of the package 1 are installed, and ventilation air is circulated and heated by switching the opening and closing doors 9 and guiding the ventilation to the outer peripheral part of the air duct 10 inside the package 1. Freezing of cooling water system equipment is prevented.

図４は、本発明の凍結防止方法の第４の実施例が適用される燃料電池発電装置の構成図で、図３に示した構成に、さらに、加熱された換気空気を集中的に送る第２の導風管を備えたものである。すなわち、本図の構成では、パッケージ１の内部の導風管１０の外周部を流れる換気を凍結防止機器７へと集中的に導く円管状の導風管８が配設されており、この導風管８を通して加熱された換気空気を集中的に送ることができるので、特に留意すべき機器の凍結防止に有効である。   FIG. 4 is a block diagram of a fuel cell power generator to which the fourth embodiment of the freeze prevention method of the present invention is applied. In the configuration shown in FIG. 3, heated ventilation air is further sent intensively. This is provided with two air ducts. That is, in the configuration of this figure, a circular wind guide tube 8 that guides ventilation flowing through the outer periphery of the air guide tube 10 inside the package 1 to the anti-freezing device 7 is provided. Since the heated ventilation air can be sent intensively through the wind pipe 8, it is effective for preventing the equipment to be particularly noted.

以上述べたように、燃料電池本体や燃料改質系機器とともに燃料電池本体用の冷却水系機器が同一パッケージ内に収納されて運転される燃料電池発電装置を、本発明のごとく構成すれば、パッケージ内が加温された換気空気によって効果的に暖められるので、外気温度が氷点下に下がる冬期の発電運転停止時においても、収納された冷却水系機器の水の凍結が確実に防止され、構成機器の損傷が回避される。したがって、本発明はこの種の燃料電池発電装置に効果的に適用される。   As described above, if the fuel cell power generator is operated as described in the present invention, the fuel cell main body and the fuel reforming system equipment and the cooling water system equipment for the fuel cell main body are housed in the same package and operated. Since the interior is effectively warmed by the heated ventilation air, the stored cooling water system equipment is reliably prevented from freezing even when the power generation operation is stopped in winter when the outside air temperature falls below freezing point. Damage is avoided. Therefore, the present invention is effectively applied to this type of fuel cell power generator.
