Description

本発明の実施形態は、燃料電池発電装置及び燃料電池発電装置の冷却水回収方法に関する。   Embodiments described herein relate generally to a fuel cell power generator and a cooling water recovery method for the fuel cell power generator.

家庭用燃料電池システムは、都市ガスやＬＰＧ等を用いて発電を行いながら、排熱を温水として回収するコジェネレーションシステムである。燃料電池が発電の際に発する熱エネルギーは冷却水によって回収される。熱エネルギーを回収した冷却水は、熱交換器で冷却された後、水タンクに供給される。水タンク内の冷却水は、ポンプによって燃料電池に供給される。熱交換器には冷却水と熱交換を行って冷却水から熱を回収するための排熱回収水が供給されており、熱交換後の排熱回収水（温水）が家庭に供給される。水タンクには、水抜きポートおよび閉止弁が設けられており、閉止弁を開けることで冷却水を抜くことができるようになっている。   A household fuel cell system is a cogeneration system that collects exhaust heat as hot water while generating power using city gas, LPG, or the like. Thermal energy generated by the fuel cell during power generation is recovered by cooling water. The cooling water from which the thermal energy has been recovered is supplied to a water tank after being cooled by a heat exchanger. The cooling water in the water tank is supplied to the fuel cell by a pump. The heat exchanger is supplied with exhaust heat recovery water for exchanging heat with the cooling water and recovering heat from the cooling water, and the exhaust heat recovery water (hot water) after the heat exchange is supplied to the home. The water tank is provided with a drain port and a shut-off valve, and the coolant can be drained by opening the shut-off valve.

このような家庭用燃料電池システムが、入居者の決まっていない新築の家屋に設置される場合、設置時に試運転等を行った後、無電源の状態で長期間保管されることとなる。このような状態で冬期になると、システム内の水が凍結し、装置の故障原因となる。したがって、試運転等を行った後は冷却水を除去しておくことが一般的である。   When such a household fuel cell system is installed in a newly built house in which no resident has been determined, it is stored for a long time in a state of no power supply after performing a test run at the time of installation. When it is winter in such a state, water in the system freezes, causing a failure of the apparatus. Therefore, it is common to remove the cooling water after a trial run or the like.

冷却水を除去する方法として、空気パージにより冷却水を水タンクに回収するものが知られている。しかし、このような手法は空気を導入するための遮断弁が必要となり、システムが複雑化し、装置コストが増加するという問題があった。   As a method for removing the cooling water, a method of collecting the cooling water in a water tank by air purge is known. However, such a method requires a shut-off valve for introducing air, which complicates the system and increases the device cost.

以下、本発明の実施の形態を図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

（第１の実施形態）図１及び図２に第１の実施形態に係る燃料電池発電装置の概略構成を示す。図１は燃料電池発電装置の運転時の構成を示し、図２は燃料電池発電装置から冷却水を回収する時の構成を示している。   (First Embodiment) FIGS. 1 and 2 show a schematic configuration of a fuel cell power generator according to a first embodiment. FIG. 1 shows a configuration during operation of the fuel cell power generator, and FIG. 2 shows a configuration when cooling water is recovered from the fuel cell power generator.

図１に示すように、燃料電池発電装置は、燃料電池１０３と、燃料ブロワ１０１から供給された燃料（例えばＬＰＧ）を触媒に接触させて水素リッチな改質ガスを生成し、この改質ガスを燃料電池１０３に供給する改質器１０２と、燃料電池１０３に空気を供給する空気ブロワ１０６とを備えている。空気ブロワ１０６の空気流路上流側には空気流量計１０５が設けられており、空気流量計１０５の測定結果に基づいて、空気ブロワ１０６から一定量の空気が燃料電池１０３に供給されるようになっている。また、燃料電池１０３には、空気やガスを排気する排気部（図示せず）が設けられている。   As shown in FIG. 1, the fuel cell power generator generates a hydrogen-rich reformed gas by bringing a fuel (for example, LPG) supplied from the fuel cell 103 and the fuel blower 101 into contact with a catalyst to generate the reformed gas. Is supplied to the fuel cell 103, and an air blower 106 is provided to supply air to the fuel cell 103. An air flow meter 105 is provided on the upstream side of the air flow path of the air blower 106 so that a certain amount of air is supplied from the air blower 106 to the fuel cell 103 based on the measurement result of the air flow meter 105. It has become. Further, the fuel cell 103 is provided with an exhaust part (not shown) for exhausting air or gas.

改質器１０２にける燃料の改質反応は吸熱反応であるため、改質器１０２にはバーナ（図示せず）が設置され、バーナの燃焼熱によって改質反応が行われる。空気ブロワ１０７は、改質器１０２のバーナに空気を供給する。   Since the reforming reaction of the fuel in the reformer 102 is an endothermic reaction, a burner (not shown) is installed in the reformer 102, and the reforming reaction is performed by the combustion heat of the burner. The air blower 107 supplies air to the burner of the reformer 102.

燃料電池１０３は、図示しない電解質膜と、電解質膜を挟んで対向して設けられた燃料極（アノード極）及び酸化剤極（カソード極）とを有している。酸化剤極に空気ブロワ１０６からの空気が導入され、燃料極に改質器１０２からの改質ガスが導入されると、両極における電気化学反応によって電気（直流電力）と熱エネルギーが発生する。   The fuel cell 103 includes an electrolyte membrane (not shown), and a fuel electrode (anode electrode) and an oxidant electrode (cathode electrode) provided to face each other with the electrolyte membrane interposed therebetween. When air from the air blower 106 is introduced into the oxidizer electrode and reformed gas from the reformer 102 is introduced into the fuel electrode, electricity (DC power) and thermal energy are generated by an electrochemical reaction at both electrodes.

インバータ１０４は、燃料電池１０３から出力される直流電力を交流電力に変換し、電気機器等の電力負荷１０９に供給する。   The inverter 104 converts the DC power output from the fuel cell 103 into AC power and supplies the AC power to a power load 109 such as an electric device.

燃料電池１０３が発電の際に発する熱エネルギーは冷却水によって回収される。熱エネルギーを回収した冷却水は、熱交換器２０１において排熱回収水と熱交換を行って冷却されると、配管２０４を介して水タンク２０２に供給される。ポンプ２０３が、配管２０５を介して水タンク２０２に貯留されている冷却水を吸引し、燃料電池１０３に供給することで、冷却水が循環するようになっている。配管２０４と水タンク２０２との連結箇所は切り離すことができるように構成されている。   The thermal energy generated when the fuel cell 103 generates power is recovered by the cooling water. When the cooling water recovered from the heat energy is cooled by exchanging heat with the exhaust heat recovery water in the heat exchanger 201, the cooling water is supplied to the water tank 202 via the pipe 204. The pump 203 sucks the cooling water stored in the water tank 202 through the pipe 205 and supplies it to the fuel cell 103 so that the cooling water circulates. The connection location between the pipe 204 and the water tank 202 is configured to be disconnected.

ポンプ３０１は、熱交換器２０１に排熱回収水を供給する。熱交換器２０１における熱交換により昇温した排熱回収水は、お湯として家屋等に供給される。   The pump 301 supplies exhaust heat recovery water to the heat exchanger 201. The exhaust heat recovery water raised in temperature by heat exchange in the heat exchanger 201 is supplied as hot water to a house or the like.

次に、燃料電池発電装置から冷却水を回収する方法を、図２を用いて説明する。図２に示すように、冷却水の回収にあたり、まず、回収する冷却水を貯留する貯留容器１０８を準備する。貯留容器１０８は密閉（閉止）可能になっている。また、貯留容器１０８からは２本の配管１０９ａ、１０９ｂが延びている。   Next, a method for recovering the cooling water from the fuel cell power generator will be described with reference to FIG. As shown in FIG. 2, when collecting the cooling water, first, a storage container 108 for storing the recovered cooling water is prepared. The storage container 108 can be sealed (closed). Further, two pipes 109 a and 109 b extend from the storage container 108.

そして、配管２０４と水タンク２０２との連結箇所は切り離し、配管２０４と配管１０９ａとを連結する。水タンク２０２は大気解放となる。また、配管１０９ｂと空気ブロワ１０６の入口（空気吸引口）とを接続する。   And the connection location of the piping 204 and the water tank 202 is cut off, and the piping 204 and the piping 109a are connected. The water tank 202 is open to the atmosphere. Further, the pipe 109b and the inlet (air suction port) of the air blower 106 are connected.

そして、空気ブロワ１０６を駆動させ、空気ブロワ１０６が貯留容器１０８内の空気を吸引すると、冷却水が水タンク２０２→ポンプ２０３→燃料電池１０３→熱交換器２０１→貯留容器１０８の経路で移動し、図３に示すように、冷却水が貯留容器１０８に回収される。   Then, when the air blower 106 is driven and the air blower 106 sucks the air in the storage container 108, the cooling water moves along the path of the water tank 202 → pump 203 → fuel cell 103 → heat exchanger 201 → storage container 108. As shown in FIG. 3, the cooling water is collected in the storage container 108.

これにより、燃料電池１０３だけでなく、水タンク２０２、ポンプ２０３、熱交換器２０１内の冷却水も回収（除去）できるため、冷却水凍結によって装置に不具合が発生することを防止できる。   Thereby, since not only the fuel cell 103 but also the cooling water in the water tank 202, the pump 203, and the heat exchanger 201 can be collected (removed), it is possible to prevent a malfunction from occurring in the apparatus due to the cooling water freezing.

また、冷却水の回収にあたり、貯留容器１０８から延びた２つの配管の一方を熱交換器２０１の出口に接続し、他方を空気ブロワ１０６に接続するといった簡易な作業を行えばよく、装置構成の複雑化及び装置コストの増加を防止することができる。   Further, in collecting the cooling water, a simple operation of connecting one of the two pipes extending from the storage container 108 to the outlet of the heat exchanger 201 and connecting the other to the air blower 106 may be performed. It is possible to prevent complication and increase in apparatus cost.

このように、本実施形態によれば、簡易な構成で冷却水を容易に回収することができる。   Thus, according to the present embodiment, the cooling water can be easily recovered with a simple configuration.

上記実施形態において、冷却水の回収経路に上り勾配の経路が存在する場合、当該経路の配管径が大き過ぎると、水が移動し難くなるため、上り経路の配管の断面積は４００ｍｍ２以内にすることが好ましい。 In the above embodiment, when there is an upward gradient path in the cooling water recovery path, if the pipe diameter of the path is too large, it becomes difficult for water to move, so the cross-sectional area of the upward path pipe is within 400 mm 2 . It is preferable to do.

（第２の実施形態）図４に第２の実施形態に係る燃料電池発電装置の冷却水回収時の概略構成を示す。本実施形態は、図２に示す第１の実施形態と比較して、回収する冷却水を水タンク２０２に集める点が異なる。図４において、図２に示す第１の実施形態と同一部分には同一符号を付して説明を省略する。なお、本実施形態に係る燃料電池発電装置の運転時の構成は図１と同様である。   (Second Embodiment) FIG. 4 shows a schematic configuration of a fuel cell power generator according to a second embodiment when cooling water is recovered. The present embodiment is different from the first embodiment shown in FIG. 2 in that the recovered cooling water is collected in the water tank 202. In FIG. 4, the same parts as those of the first embodiment shown in FIG. The configuration of the fuel cell power generator according to this embodiment during operation is the same as that shown in FIG.

図４に示すように、冷却水の回収にあたり、まず、水タンク２０２の底部とポンプ２０３とを接続する配管２０５を、水タンク２０２から切り離す。配管２０５を切り離した後、水タンク２０３側の取り合いは閉止処置する。   As shown in FIG. 4, when collecting the cooling water, first, the pipe 205 connecting the bottom of the water tank 202 and the pump 203 is disconnected from the water tank 202. After disconnecting the pipe 205, the water tank 203 side is closed.

そして、水タンク２０２の上部と空気ブロワ１０６の入口とを配管２０６で接続する。水タンク２０２が大気解放されている場合は、解放部分に閉止処置を施す。   Then, the upper part of the water tank 202 and the inlet of the air blower 106 are connected by a pipe 206. When the water tank 202 is released to the atmosphere, the release portion is closed.

そして、空気ブロワ１０６を駆動させ、空気ブロワ１０６が水タンク２０２内の空気を吸引すると、冷却水がポンプ２０３→燃料電池１０３→熱交換器２０１→水タンク２０２の経路で移動し、図５に示すように、冷却水が水タンク２０２に回収される。   Then, when the air blower 106 is driven and the air blower 106 sucks the air in the water tank 202, the cooling water moves along the path of the pump 203 → the fuel cell 103 → the heat exchanger 201 → the water tank 202, and FIG. As shown, cooling water is collected in the water tank 202.

冷却水の回収後、水タンク２０２内の冷却水は水抜きポート２０７を介して燃料電池発電装置の外部の排水口に排出される。   After the cooling water is collected, the cooling water in the water tank 202 is discharged to the drain outlet outside the fuel cell power generation device via the drain port 207.

これにより、燃料電池１０３だけでなく、水タンク２０２、ポンプ２０３、熱交換器２０１内の冷却水も回収（除去）できるため、冷却水凍結によって装置に不具合が発生することを防止できる。   Thereby, since not only the fuel cell 103 but also the cooling water in the water tank 202, the pump 203, and the heat exchanger 201 can be collected (removed), it is possible to prevent a malfunction from occurring in the apparatus due to the cooling water freezing.

また、冷却水の回収にあたり、配管２０５を水タンク２０２から切り離し、水タンク２０２と空気ブロワ１０６を配管２０６で接続するといった簡易な作業を行えばよく、装置構成の複雑化及び装置コストの増加を防止することができる。   Further, when collecting the cooling water, it is only necessary to perform simple operations such as disconnecting the pipe 205 from the water tank 202 and connecting the water tank 202 and the air blower 106 with the pipe 206, thereby complicating the apparatus configuration and increasing the apparatus cost. Can be prevented.

このように、本実施形態によれば、簡易な構成で冷却水を容易に回収することができる。   Thus, according to the present embodiment, the cooling water can be easily recovered with a simple configuration.

上記第１及び第２の実施形態において、冷却水回収にあたり空気ブロワ１０６を駆動する時間は、冷却水の総量に基づいて予め定めておいてもよい。また、上記第１の実施形態において、水タンク２０２に水位計を設け、水タンク２０２の水位が所定値以下になってから所定時間経過するまで空気ブロワ１０６を駆動するようにしてもよい。   In the first and second embodiments, the time for driving the air blower 106 for cooling water recovery may be determined in advance based on the total amount of cooling water. In the first embodiment, a water level meter may be provided in the water tank 202, and the air blower 106 may be driven until a predetermined time elapses after the water level in the water tank 202 becomes a predetermined value or less.

また、上記第１及び第２の実施形態では、冷却水回収時に、配管１０９ｂ、配管２０６を空気ブロワ１０６の入口に直接接続していたが、図６及び図７に示すように、空気流量計１０５を介して空気ブロワ１０６に接続してもよい。そして、冷却水の回収を開始してから、空気流量計１０５で測定した空気ブロワ１０６の吐出量の積算値が所定値になるまで、空気ブロワ１０６を駆動するようにしてもよい。   In the first and second embodiments, the pipe 109b and the pipe 206 are directly connected to the inlet of the air blower 106 at the time of cooling water recovery. However, as shown in FIGS. It may be connected to the air blower 106 via 105. Then, the air blower 106 may be driven until the integrated value of the discharge amount of the air blower 106 measured by the air flow meter 105 reaches a predetermined value after the collection of the cooling water is started.

上記第１及び第２の実施形態では、冷却水回収時に、貯留容器１０８内の空気、水タンク２０２内の空気を空気ブロワ１０６で吸引していたが、吸引機能を有する他の装置で行ってもよい。   In the first and second embodiments, the air in the storage container 108 and the air in the water tank 202 are sucked by the air blower 106 at the time of cooling water recovery, but this is performed by another device having a suction function. Also good.

上記第１及び第２の実施形態では、燃料電池発電装置を例に説明を行ったが、発熱を伴う発電部と、発電部で発生した熱を回収する冷却剤を有する他のシステム、例えば車載用燃料電池や一般のコジェネレーションシステムにも適用することができる。   In the first and second embodiments, the fuel cell power generation device has been described as an example. However, another system having a power generation unit that generates heat and a coolant that recovers heat generated in the power generation unit, for example, in-vehicle It can also be applied to fuel cells for general use and general cogeneration systems.

以上説明したように、少なくとも一つの実施形態のよれば、簡易な構成で冷却水を容易に回収できる。   As described above, according to at least one embodiment, the cooling water can be easily recovered with a simple configuration.

本発明のいくつかの実施形態を説明したが、これらの実施形態は、例として提示したものであり、発明の範囲を限定することは意図していない。これら新規な実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行うことができる。これら実施形態やその変形は、発明の範囲や要旨に含まれるとともに、特許請求の範囲に記載された発明とその均等の範囲に含まれる。   Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
