　≪第１実施形態≫
　以下、第１実施形態を説明する。 First Embodiment
The first embodiment will be described below.
　図１は、第１実施形態の燃料電池発電装置を備える燃料電池発電システムの構成例を示す図である。図１に示す燃料電池発電システム２０１は、並列に接続された複数のＦＣ（燃料電池）プラットフォームによって発電された電力を、給電対象である外部装置１２に供給するシステムである。燃料電池発電システム２０１の用途の具体例として、定置用の発電システム、港湾クレーンなどの荷役機械用の発電システム、船舶用の発電システムなどが挙げられる。その他には、鉄道用、建設機械用などもある。燃料電池発電システム２０１の用途は、これらの例に限られず、燃料電池発電システム２０１は、他のアプリケーションに適用されてもよい。 FIG. 1 is a diagram showing an example of the configuration of a fuel cell power generation system including a fuel cell power generation device of the first embodiment. The fuel cell power generation system 201 shown in FIG. 1 is a system that supplies power generated by multiple FC (fuel cell) platforms connected in parallel to an external device 12 that is the power supply target. Specific examples of uses of the fuel cell power generation system 201 include stationary power generation systems, power generation systems for loading and unloading machinery such as port cranes, and power generation systems for ships.

　燃料電池発電システム２０１は、燃料電池発電装置１０１と補機システム３０１を備える。 The fuel cell power generation system 201 includes a fuel cell power generation device 101 and an auxiliary system 301.
　補機システム３０１は、主機である燃料電池発電装置１０１に接続される複数の補機を含み、燃料電池発電装置１０１の稼働を補助する周辺システムである。図１は、複数の補機として、制御用電源３２、パージ系統３０、燃料系統１８、給気系統１９、出力線１７、電力変換装置１１、ＤＣ／ＤＣコンバータ１３、二次電池１４、排気系統３１及び冷却器１５を例示する。複数の補機の一部又は全部は、燃料電池発電装置１０１に内蔵されてもよいし、ユニット化されてもよい。燃料電池発電装置１０１は、複数の補機の一部又は全部を、燃料電池発電装置１０１の内部に備えてもよいし、燃料電池発電装置１０１の外部に備えてもよい。 The auxiliary system 301 is a peripheral system that includes multiple auxiliary devices connected to the fuel cell power generation apparatus 101, which is the main unit, and assists the operation of the fuel cell power generation apparatus 101. FIG. 1 shows the multiple auxiliary devices as examples of a control power supply 32, a purge system 30, a fuel system 18, an air supply system 19, an output line 17, a power conversion device 11, a DC/DC converter 13, a secondary battery 14, an exhaust system 31, and a cooler 15. Some or all of the multiple auxiliary devices may be built into the fuel cell power generation apparatus 101, or may be unitized. The fuel cell power generation apparatus 101 may include some or all of the multiple auxiliary devices inside the fuel cell power generation apparatus 101, or may be external to the fuel cell power generation apparatus 101.
　燃料電池発電装置１０１は、外部装置１２に供給される電力を複数のＦＣプラットフォームによって発電する。燃料電池発電装置１０１は、ユニット化されてもよい。燃料電池発電装置１０１は、出力線１７に並列に接続された複数のＦＣプラットフォーム（この例では、３つのＦＣプラットフォーム１，２，３）と、それらの複数のＦＣプラットフォームを制御する制御装置１０とを備える。並列に接続される複数のＦＣプラットフォームの台数は、３台に限られず、２台でも、４台以上でもよい。 The fuel cell power generation device 101 generates power to be supplied to an external device 12 using multiple FC platforms. The fuel cell power generation device 101 may be unitized. The fuel cell power generation device 101 includes multiple FC platforms (in this example, three FC platforms 1, 2, and 3) connected in parallel to an output line 17, and a control device 10 that controls the multiple FC platforms. The number of multiple FC platforms connected in parallel is not limited to three, and may be two, four, or more.
　ＦＣプラットフォーム１，２，３は、それぞれ、共通の出力線１７に出力点１６を経由して接続されるＦＣスタックを含む。ＦＣスタックは、燃料電池の一例である。ＦＣプラットフォーム１は、ＦＣスタック２１を含み、ＦＣプラットフォーム２は、ＦＣスタック２２を含み、ＦＣプラットフォーム３は、ＦＣスタック２３を含む。 FC platforms 1, 2, and 3 each include an FC stack connected to a common output line 17 via an output point 16.

The FC stacks 21, 22, and 23 generate electricity through an electrochemical reaction between hydrogen or hydrogen-rich gas supplied via a fuel system 18 including a fuel pipe and oxygen contained in air supplied from the outside via an air supply system 19 including an air pipe. The power generation state of the FC stacks 21, 22, and 23 ( FC platforms 1, 2, and 3) is controlled by the control device 10. Exhaust gas generated by the electrochemical reaction of the FC stacks 21, 22, and 23 is discharged via an exhaust system 31 including an exhaust pipe.

The single cell has a membrane-electrode assembly (MEA) in which both sides of a polymer electrolyte membrane for selectively transporting hydrogen ions are sandwiched between a pair of electrodes formed of a porous material, and a pair of separators that sandwich the MEA from both sides. Each of the pair of electrodes has a catalyst layer mainly composed of carbon powder that supports a platinum-based metal catalyst (electrode catalyst), for example, and a gas diffusion layer that is both breathable and electronically conductive.
　ＦＣスタック２１，２２，２３には、それらの出力端子の電圧を検出するための電圧センサと、それらの出力端子からの出力電流を検出するための電流センサが取り付けられている。制御装置１０は、ＦＣスタック２１，２２，２３から出力される各電圧の検出値を電圧センサにより取得し、ＦＣスタック２１，２２，２３から出力される各電流の検出値を電流センサにより取得する。制御装置１０は、各電圧の検出値と各電流の検出値を用いて、ＦＣスタック２１，２２，２３の各出力電力ｐ１，ｐ２，ｐ３を検出する。 The FC stacks 21, 22, and 23 are fitted with voltage sensors for detecting the voltages at their output terminals, and current sensors for detecting the output currents from their output terminals. The control device 10 obtains the detection values of the voltages output from the FC stacks 21, 22, and 23 using the voltage sensors, and obtains the detection values of the currents output from the FC stacks 21, 22, and 23 using the current sensors. The control device 10 detects the output powers p1, p2, and p3 of the FC stacks 21, 22, and 23 using the detection values of the voltages and currents.
　燃料電池発電装置１０１内のＦＣスタック２１，２２，２３（ＦＣプラットフォーム１，２，３）の発電により生成された発電電力は、電力変換装置１１を介して、外部装置１２に供給される。 The power generated by the FC stacks 21, 22, 23 ( FC platforms 1, 2, 3) in the fuel cell power generation device 101 is supplied to the external device 12 via the power conversion device 11.

The power conversion device 11 is, for example, an inverter that converts DC power obtained by power generation in the FC stacks 21, 22, and 23 into AC power and supplies it to the external device 12. Specific examples of inverters include a power conditioning system (PCS) and a grid-connected inverter. When the external device 12 is a motor, the power conversion device 11 may be an inverter that drives the motor. The power conversion device 11 may be a converter that converts the voltage of the DC power obtained by power generation in the FC stacks 21, 22, and 23 into DC power of a different voltage and supplies it to the external device 12.

The power Pb discharged from the secondary battery 14 is supplied to the external device 12 via the power conversion device 11. The power Pb input (regenerated) from the external device 12 via the power conversion device 11 may be charged to the secondary battery 14. The charging or discharging of the secondary battery 14 is controlled by the DC/DC converter 13 that operates according to a drive control signal from the control device 10.

　図１は、燃料電池発電装置１０１がＦＣプラットフォーム１，２，３に共通の制御用電源３２を備える形態を例示する。ＦＣプラットフォーム１，２，３の電源が制御用電源３２に共通化されることで、複数の制御用電源を備える形態の場合に比べて、燃料電池発電システム２０１及び燃料電池発電装置１０１を小型化できる。 FIG. 1 illustrates an example of a configuration in which a fuel cell power generation device 101 has a control power supply 32 common to FC platforms 1, 2, and 3. By sharing the power supply for FC platforms 1, 2, and 3 as a control power supply 32, the fuel cell power generation system 201 and the fuel cell power generation device 101 can be made smaller than in a configuration in which multiple control power supplies are provided.
　燃料電池発電装置１０１は、ＦＣプラットフォーム１，２，３に個別の制御用電源３２を備えてもよい。複数のＦＣプラットフォームの電源が個別に複数用意されることで、複数の制御用電源のうち一部の電源が故障又はメンテナンス等により使用不能な場合でも、残りの電源を用いて複数のＦＣプラットフォームの一部又は全部の動作を継続できる。 The fuel cell power generation device 101 may be provided with individual control power supplies 32 for the FC platforms 1, 2, and 3.

The fuel cell power generation device 101 includes, for example, a control device 10 and multiple FC platforms 1, 2, and 3. The FC platform 1 includes, for example, a fuel pipe 118, an air pipe 119, an air filter 33, an exhaust pipe 131, a first cooling system 36, a second cooling system 90, and an FC unit 51. The FC unit 51 includes an FC stack 21, a boost converter 42, a hydrogen pump 43, an air compressor 45, a water pump 44, an air inlet shutoff valve 77, and an exhaust air outlet shutoff valve 78, etc. The boost converter 42, the hydrogen pump 43, the air compressor 45, the water pump 44, the air inlet shutoff valve 77, and the exhaust air outlet shutoff valve 78, etc. are controlled by the control device 10. The FC platforms 2 and 3 have the same configuration and function as the FC platform 1, and are controlled by the control device 10 in the same manner as the FC platform 1. Therefore, the explanation of FC platforms 2 and 3 will be omitted, as the explanation of FC platform 1 will be used.
　ＦＣスタック２１は、燃料極７１と空気極７２を有する。ＦＣスタック２１は、燃料極７１に供給された水素又は水素リッチなガスと、空気極７２に供給された空気に含まれる酸素との電気化学反応によって発電する。ＦＣスタック２１は、昇圧コンバータ４２を介して、出力線１７に接続されている。昇圧コンバータ４２は、ＦＣスタック２１から出力された電圧を昇圧し、昇圧後の直流電力を出力点１６を経由して出力線１７に出力するＤＣ／ＤＣコンバータである。複数のＦＣプラットフォーム１，２，３における複数のＦＣスタック２１，２２，２３の出力電力は、対応する昇圧コンバータ４２を介して、共通の出力線１７に出力される。 The FC stack 21 has a fuel electrode 71 and an air electrode 72. The FC stack 21 generates electricity by an electrochemical reaction between hydrogen or hydrogen-rich gas supplied to the fuel electrode 71 and oxygen contained in the air supplied to the air electrode 72. The FC stack 21 is connected to the output line 17 via a boost converter 42. The boost converter 42 is a DC/DC converter that boosts the voltage output from the FC stack 21 and outputs the boosted DC power to the output line 17 via the output point 16. The output power of the multiple FC stacks 21, 22, and 23 in the multiple FC platforms 1, 2, and 3 is output to a common output line 17 via the corresponding boost converters 42.
　燃料管１１８は、複数のＦＣプラットフォーム１，２，３に共通に接続された燃料系統１８から水素が供給される。燃料管１１８は、燃料極７１に入口７５を介して水素を供給する。 The fuel pipe 118 is supplied with hydrogen from a fuel system 18 commonly connected to the multiple FC platforms 1, 2, and 3. The fuel pipe 118 supplies hydrogen to the fuel electrode 71 via the inlet 75.
　空気管１１９は、複数のＦＣプラットフォーム１，２，３に共通に接続された給気系統１９から空気が供給される。空気管１１９は、ＦＣスタック２１の空気極７２に入口７３を介して空気を供給する。空気管１１９は必須ではなく、ＦＣプラットフォーム１，２，３の開放部から空気フィルタ３３が直接空気を吸い込んでもよい。 Air is supplied to the air pipe 119 from an air supply system 19 commonly connected to the multiple FC platforms 1, 2, and 3. The air pipe 119 supplies air to the air electrode 72 of the FC stack 21 via an inlet 73. The air pipe 119 is not essential, and the air filter 33 may directly draw in air from the open parts of the FC platforms 1, 2, and 3.
　空気フィルタ３３は、給気系統１９及び空気管１１９を介して供給される空気に含まれる塵や燃料電池に悪影響を及ぼす不純物を取り除いて、空気コンプレッサ４５に空気管１２０を介して供給する。空気フィルタは、エアクリーナーとも称される。 The air filter 33 removes dust and impurities that may adversely affect the fuel cell from the air supplied via the air supply system 19 and air pipe 119, and supplies the air to the air compressor 45 via the air pipe 120. The air filter is also called an air cleaner.
　空気コンプレッサ４５は、空気フィルタ３３を通して供給された空気を圧縮し、ＦＣスタック２１の空気極７２に供給する。空気コンプレッサ４５により圧縮された酸素を含む空気は、ＦＣスタック２１の空気極７２に入口７３を介して供給される。空気入口遮断弁７７は、空気コンプレッサ４５から空気極７２の入口７３へ供給される空気の流れを遮断する。 The air compressor 45 compresses the air supplied through the air filter 33 and supplies it to the air electrode 72 of the FC stack 21. The oxygen-containing air compressed by the air compressor 45 is supplied to the air electrode 72 of the FC stack 21 via the inlet 73. The air inlet shutoff valve 77 shuts off the flow of air supplied from the air compressor 45 to the inlet 73 of the air electrode 72.
　排気管１３１は、複数のＦＣプラットフォーム１，２，３に共通に接続された排気系統３１に、ＦＣスタック２１で発生する排ガスを排出する。排空気出口遮断弁７８は、ＦＣスタック２１の空気極７２の出口７４から排気管１３１に排出されるオフガスの流れを遮断する。 The exhaust pipe 131 discharges exhaust gas generated in the FC stack 21 to an exhaust system 31 commonly connected to multiple FC platforms 1, 2, and 3. The exhaust air outlet shutoff valve 78 shuts off the flow of off-gas discharged from the outlet 74 of the air electrode 72 of the FC stack 21 to the exhaust pipe 131.
　第１冷却系統３６は、ＦＣスタック２１を冷却水等の第１冷却液によって冷却する。第１冷却系統３６は、冷熱源３９との間で第１冷却液の熱交換を行って第１冷却液を冷却する第１中間熱交換器３４を有する。ウォーターポンプ４４は、第１冷却液を、第１中間熱交換器３４とＦＣスタック２１との間で循環させる。ウォーターポンプ４４により循環された第１冷却液により、ＦＣスタック２１は冷却される。 The first cooling system 36 cools the FC stack 21 with a first cooling liquid such as cooling water. The first cooling system 36 has a first intermediate heat exchanger 34 that exchanges heat with a cold source 39 to cool the first cooling liquid. The water pump 44 circulates the first cooling liquid between the first intermediate heat exchanger 34 and the FC stack 21. The FC stack 21 is cooled by the first cooling liquid circulated by the water pump 44.
　第１中間熱交換器３４は、ＦＣスタック２１を冷却する第１冷却液を異種の冷熱源３９との間で熱交換可能な熱交換器である。異種の冷熱源３９とは、利用する冷熱源３９の種類を問わないことを意味する。第１中間熱交換器３４は、利用する冷熱源３９の種類を問わずに、任意の冷熱源３９で第１冷却液を冷却できるので、上記のような様々な用途に適用可能な燃料電池発電装置１０１が実現される。 The first intermediate heat exchanger 34 is a heat exchanger capable of exchanging heat between the first cooling liquid that cools the FC stack 21 and a different type of cold heat source 39. The different types of cold heat sources 39 mean that the type of cold heat source 39 used does not matter. The first intermediate heat exchanger 34 can cool the first cooling liquid with any cold heat source 39, regardless of the type of cold heat source 39 used, thereby realizing a fuel cell power generation device 101 that can be used for various purposes such as those described above.
　第１中間熱交換器３４は、第１冷却系統３６を循環する第１冷却液が通過する放熱部４０と、冷熱源３９との間で熱を移動させる熱媒が通過する受熱部４１と、を有する。冷熱源３９から供給される熱媒は、液体でも気体でもよい。第１中間熱交換器３４において放熱部４０から受熱部４１へ放熱されることで、第１冷却液は、冷却される。第１中間熱交換器３４の具体例として、プレート熱交換器などが挙げられるが、第１中間熱交換器３４は、これに限られない。 The first intermediate heat exchanger 34 has a heat dissipation section 40 through which the first cooling liquid circulating in the first cooling system 36 passes, and a heat receiving section 41 through which a heat medium passes to transfer heat between the cold heat source 39. The heat medium supplied from the cold heat source 39 may be liquid or gas. The first cooling liquid is cooled by dissipating heat from the heat dissipation section 40 to the heat receiving section 41 in the first intermediate heat exchanger 34. A specific example of the first intermediate heat exchanger 34 is a plate heat exchanger, but the first intermediate heat exchanger 34 is not limited to this.
　複数のＦＣプラットフォーム１，２，３における複数の第１中間熱交換器３４は、それぞれ、複数のＦＣプラットフォーム１，２，３に共通に接続される冷熱源３９との間で熱交換してもよい。これにより、冷熱源３９が複数のＦＣプラットフォーム１，２，３間で共通化されるので、燃料電池発電装置１０１を小型化できる。なお、冷熱源３９は、複数のＦＣプラットフォーム１，２，３間で相違してもよい。 The multiple first intermediate heat exchangers 34 in the multiple FC platforms 1, 2, 3 may each exchange heat with a cold heat source 39 that is commonly connected to the multiple FC platforms 1, 2, 3. This allows the cold heat source 39 to be common between the multiple FC platforms 1, 2, 3, making it possible to reduce the size of the fuel cell power generation device 101. Note that the cold heat source 39 may be different between the multiple FC platforms 1, 2, 3.
　第２冷却系統９０は、空気コンプレッサ４５を冷却水等の第２冷却液によって冷却する。第２冷却系統９０は、冷熱源９４との間で第２冷却液の熱交換を行って第２冷却液を冷却する第２中間熱交換器９２を有する。ポンプ９１は、第２冷却液を、第２中間熱交換器９２と空気コンプレッサ４５との間で循環させる。ポンプ９１により循環された第２冷却液により、空気コンプレッサ４５は冷却される。 The second cooling system 90 cools the air compressor 45 with a second cooling liquid such as cooling water. The second cooling system 90 has a second intermediate heat exchanger 92 that exchanges heat with a cold source 94 to cool the second cooling liquid. The pump 91 circulates the second cooling liquid between the second intermediate heat exchanger 92 and the air compressor 45. The air compressor 45 is cooled by the second cooling liquid circulated by the pump 91.
　第２中間熱交換器９２は、空気コンプレッサ４５を冷却する第２冷却液を異種の冷熱源９４との間で熱交換可能な熱交換器である。異種の冷熱源９４とは、利用する冷熱源９４の種類を問わないことを意味する。第２中間熱交換器９２は、利用する冷熱源９４の種類を問わずに、任意の冷熱源９４で第２冷却液を冷却できるので、上記のような様々な用途に適用可能な燃料電池発電装置１０１が実現される。 The second intermediate heat exchanger 92 is a heat exchanger capable of exchanging heat between the second cooling liquid, which cools the air compressor 45, and a different type of cold heat source 94. The different types of cold heat sources 94 mean that the type of cold heat source 94 used does not matter. The second intermediate heat exchanger 92 can cool the second cooling liquid with any cold heat source 94, regardless of the type of cold heat source 94 used, thereby realizing a fuel cell power generation device 101 that can be used for various purposes such as those described above.
　第２中間熱交換器９２は、第２冷却系統９０を循環する第２冷却液が通過する放熱部９５と、冷熱源９４との間で熱を移動させる熱媒が通過する受熱部９６と、を有する。冷熱源９４から供給される熱媒は、液体でも気体でもよい。第２中間熱交換器９２において放熱部９５から受熱部９６へ放熱されることで、第２冷却液は、冷却される。第２中間熱交換器９２の具体例として、プレート熱交換器などが挙げられるが、第２中間熱交換器９２は、これに限られない。 The second intermediate heat exchanger 92 has a heat dissipation section 95 through which the second cooling liquid circulating in the second cooling system 90 passes, and a heat receiving section 96 through which a heat medium passes to transfer heat between the cold heat source 94. The heat medium supplied from the cold heat source 94 may be liquid or gas. The second cooling liquid is cooled by dissipating heat from the heat dissipation section 95 to the heat receiving section 96 in the second intermediate heat exchanger 92. A specific example of the second intermediate heat exchanger 92 is a plate heat exchanger, but the second intermediate heat exchanger 92 is not limited to this.
　複数のＦＣプラットフォーム１，２，３における複数の第２中間熱交換器９２は、それぞれ、複数のＦＣプラットフォーム１，２，３に共通に接続される冷熱源９４との間で熱交換してもよい。これにより、冷熱源９４が複数のＦＣプラットフォーム１，２，３間で共通化されるので、燃料電池発電装置１０１を小型化できる。なお、冷熱源９４は、複数のＦＣプラットフォーム１，２，３間で相違してもよい。 The multiple second intermediate heat exchangers 92 in the multiple FC platforms 1, 2, 3 may each exchange heat with a cold heat source 94 that is commonly connected to the multiple FC platforms 1, 2, 3. This allows the cold heat source 94 to be common between the multiple FC platforms 1, 2, 3, making it possible to reduce the size of the fuel cell power generation device 101. Note that the cold heat source 94 may be different between the multiple FC platforms 1, 2, 3.
　冷却器１５（図１）は、冷熱源３９又は冷熱源９４の一例である。冷熱源３９又は冷熱源９４は、例えば、空冷冷却器、開放式冷却塔、密閉式冷却塔、工場の冷却水、上水、河川水、海水、液化水素の気化熱、または圧縮水素が膨張した際の冷熱などである。 The cooler 15 (Figure 1) is an example of the cold heat source 39 or the cold heat source 94. The cold heat source 39 or the cold heat source 94 is, for example, an air-cooled cooler, an open cooling tower, a closed cooling tower, cooling water in a factory, drinking water, river water, seawater, the heat of vaporization of liquefied hydrogen, or the cold heat generated when compressed hydrogen expands.
　第１中間熱交換器３４の受熱部４１の素材は、例えば、金属イオンの溶出性が比較的低い低溶出性金属（例えば、高耐食のオーステナイト系ステンレス（ＳＵＳ３１６Ｌ）など）である。受熱部４１に接触する熱媒が海水などであると、受熱部４１の素材によっては、金属イオンが受熱部４１から溶出するおそれがある。受熱部４１の素材が上記のような低溶出性金属であると、冷熱源３９から供給される熱媒の制約が緩和されるので、冷熱源３９の選択肢が増える。その結果、上記のような様々な用途に適用可能な燃料電池発電装置１０１が実現される。これは、第２中間熱交換器９２の受熱部９６の素材についても同様である。 The material of the heat receiving portion 41 of the first intermediate heat exchanger 34 is, for example, a low-elution metal with a relatively low elution rate of metal ions (such as highly corrosion-resistant austenitic stainless steel (SUS316L)). If the heat medium in contact with the heat receiving portion 41 is seawater or the like, there is a risk that metal ions will elute from the heat receiving portion 41, depending on the material of the heat receiving portion 41. If the material of the heat receiving portion 41 is a low-elution metal as described above, the restrictions on the heat medium supplied from the cold heat source 39 are alleviated, and the options for the cold heat source 39 increase. As a result, a fuel cell power generation device 101 that can be used for various applications such as those described above is realized. The same applies to the material of the heat receiving portion 96 of the second intermediate heat exchanger 92.
　また、第１中間熱交換器３４の採用によって、第１冷却液が循環する経路をＦＣプラットフォームの外側の冷熱源３９まで伸ばさなくても、第１冷却液を放熱できる。つまり、第１冷却液が循環する経路を短縮でき、燃料電池を冷却する高価な第１冷却液の使用量を削減できる。その結果、コスト低減が可能となる。同様に、第２中間熱交換器９２の採用によっても、第２冷却液の使用量を削減でき、コスト低減が可能となる。 Furthermore, by employing the first intermediate heat exchanger 34, the first coolant can dissipate heat without having to extend the path through which the first coolant circulates to the cold heat source 39 outside the FC platform. In other words, the path through which the first coolant circulates can be shortened, and the amount of expensive first coolant used to cool the fuel cell can be reduced. As a result, costs can be reduced. Similarly, by employing the second intermediate heat exchanger 92, the amount of second coolant used can be reduced, and costs can be reduced.
　第２中間熱交換器９２が第２冷却液の熱を放熱する冷熱源９４は、第１中間熱交換器３４が第１冷却液の熱を放熱する冷熱源３９と同じでも異なってもよい。冷熱源９４と冷熱源３９が同じであれば、冷熱源が第１中間熱交換器３４と第２中間熱交換器９２との間で共通化されるので、燃料電池発電装置１０１を小型化できる。 The cold heat source 94 from which the second intermediate heat exchanger 92 dissipates heat of the second cooling liquid may be the same as or different from the cold heat source 39 from which the first intermediate heat exchanger 34 dissipates heat of the first cooling liquid. If the cold heat source 94 and the cold heat source 39 are the same, the cold heat source is shared between the first intermediate heat exchanger 34 and the second intermediate heat exchanger 92, so that the fuel cell power generation device 101 can be made smaller.
　第１冷却系統３６は、第１冷却液からイオンを取り除くイオン交換器３５を備えてもよい。第１冷却液からのイオンの取り除きによって、ＦＣスタック２１において入出力される第１冷却液の電気伝導度の上昇が抑制されるので、ＦＣスタック２１と第１冷却液との間の電気的な干渉が抑制される。 The first cooling system 36 may include an ion exchanger 35 that removes ions from the first cooling liquid. By removing ions from the first cooling liquid, an increase in the electrical conductivity of the first cooling liquid inputted and outputted to the FC stack 21 is suppressed, thereby suppressing electrical interference between the FC stack 21 and the first cooling liquid.
　また、第１中間熱交換器３４が採用されることで、第１冷却系統３６側の第１冷却液から冷熱源３９側の熱媒へのイオンの溶出が抑制されるので、イオン交換器３５のメンテナンスの頻度が低減する。 In addition, by adopting the first intermediate heat exchanger 34, the elution of ions from the first cooling liquid on the first cooling system 36 side to the heat medium on the cold heat source 39 side is suppressed, thereby reducing the frequency of maintenance of the ion exchanger 35.
　第１冷却系統３６は、第１冷却液の電気伝導度を測定するセンサ３７を備えてもよい。センサ３７を備えることで、第１冷却液の電気伝導度を管理できる。例えば、電気伝導度が上昇し始めたことがセンサ３７により検知された場合、ユーザは、イオン交換器３５をメンテナンスするタイミングを把握できる。また、電気伝導度を管理することで燃料電池の直流ＰＮ間（プラスとマイナス間）の絶縁性を保つことができる。センサ３７又は制御装置１０は、電気伝導度が第１閾値（例えば、１μＳ／ｃｍ）以上と測定された場合、ユーザが認知できるように、警報を発報してもよい。制御装置１０は、電気伝導度が第１閾値よりも大きな第２閾値（例えば、５μＳ／ｃｍ）以上と測定された場合、第２閾値以上の電気伝導度が測定されたＦＣプラットフォームを停止させてもよい。 The first cooling system 36 may include a sensor 37 that measures the electrical conductivity of the first cooling liquid. By including the sensor 37, the electrical conductivity of the first cooling liquid can be managed. For example, if the sensor 37 detects that the electrical conductivity has started to increase, the user can know when to perform maintenance on the ion exchanger 35. In addition, by managing the electrical conductivity, the insulation between the DC PN (between the positive and negative) of the fuel cell can be maintained. If the electrical conductivity is measured to be equal to or greater than a first threshold value (e.g., 1 μS/cm), the sensor 37 or the control device 10 may issue an alarm so that the user can be aware of the alarm. If the electrical conductivity is measured to be equal to or greater than a second threshold value (e.g., 5 μS/cm) that is greater than the first threshold value, the control device 10 may stop the FC platform in which the electrical conductivity equal to or greater than the second threshold value is measured.
　第１冷却系統３６は、第１冷却液の温度変化に伴う膨張又は収縮を吸収する第１タンク３８を備えてもよい。これにより、第１冷却液の温度変化に伴う膨張又は収縮が抑制される。 The first cooling system 36 may include a first tank 38 that absorbs the expansion or contraction of the first cooling liquid caused by temperature changes. This suppresses the expansion or contraction of the first cooling liquid caused by temperature changes.
　同様に、第２冷却系統９０は、第２冷却液の温度変化に伴う膨張又は収縮を吸収する第２タンク９３を備えてもよい。これにより、第２冷却液の温度変化に伴う膨張又は収縮が抑制される。 Similarly, the second cooling system 90 may include a second tank 93 that absorbs the expansion or contraction of the second cooling liquid caused by temperature changes. This suppresses the expansion or contraction of the second cooling liquid caused by temperature changes.
　ＦＣプラットフォーム１は、第１気液分離器７９及び水素ポンプ４３を備えてもよい。第１気液分離器７９は、燃料極７１の出口７６から排出される第１混相流から水素ガスと排水を分離する。水素ポンプ４３は、第１気液分離器７９により分離された水素ガスを燃料極７１の入口７５へ循環させる。これにより、ＦＣスタック２１での発電により生成された余剰の水素ガスを、ＦＣスタック２１での発電に再利用できる。 The FC platform 1 may include a first gas-liquid separator 79 and a hydrogen pump 43. The first gas-liquid separator 79 separates hydrogen gas and wastewater from the first multiphase flow discharged from the outlet 76 of the fuel electrode 71. The hydrogen pump 43 circulates the hydrogen gas separated by the first gas-liquid separator 79 to the inlet 75 of the fuel electrode 71. This allows surplus hydrogen gas produced by power generation in the FC stack 21 to be reused for power generation in the FC stack 21.
　ＦＣプラットフォーム１は、混合器８０を備えてもよい。排気管１３１は、第１気液分離器７９により分離された排水と、当該排水に混入する水素と、空気極７２の出口７４から排出される排空気とを混合器８０で合流させた第２混相流を排出する。これにより、排水と水素と排空気をまとめて排出できる。 The FC platform 1 may also include a mixer 80. The exhaust pipe 131 discharges a second multiphase flow obtained by combining the wastewater separated by the first gas-liquid separator 79, hydrogen mixed in the wastewater, and exhaust air discharged from the outlet 74 of the air electrode 72 in the mixer 80. This allows the wastewater, hydrogen, and exhaust air to be discharged together.
　ＦＣプラットフォーム１は、第２混相流から水と気体を分離する第２気液分離器８１を備えてもよい。これにより、排水と排ガスを分離して排出できる。排水又は排ガスは、回収器８２により回収されてもよい。これにより、排水又は排ガスによる周辺の汚染が抑制される。 The FC platform 1 may be provided with a second gas-liquid separator 81 that separates water and gas from the second multiphase flow. This allows the wastewater and exhaust gas to be separated and discharged. The wastewater or exhaust gas may be collected by a collector 82. This prevents the surrounding area from being polluted by the wastewater or exhaust gas.
　燃料電池発電装置１０１は、複数のＦＣプラットフォーム１，２，３における複数の燃料管１１８に窒素等の不活性ガスを個別に供給するパージ系統３０を備えてもよい。パージ系統３０は、複数の燃料管１１８を不活性ガスで個別にパージできるように、バルブで流路を切り替えてもよい。これにより、不活性ガスのパージによる特性劣化をＦＣスタック単位で管理できる。 The fuel cell power generation device 101 may be equipped with a purge system 30 that individually supplies an inert gas such as nitrogen to the multiple fuel pipes 118 in the multiple FC platforms 1, 2, and 3. The purge system 30 may switch the flow path with a valve so that the multiple fuel pipes 118 can be individually purged with the inert gas. This makes it possible to manage the deterioration of characteristics due to purging with the inert gas on a per-FC stack basis.
　ＦＣスタック２１の出力電力ｐ１の一部は、ＦＣユニット５１内の空気コンプレッサ４５等の補機の動作電力として使用され、その余剰電力が、ＦＣユニット５１の出力電力Ｐ１として出力される。ＦＣスタック２２の出力電力ｐ２及びＦＣスタック２３の出力電力ｐ３についても同様である。 A portion of the output power p1 of the FC stack 21 is used as operating power for auxiliary equipment such as the air compressor 45 in the FC unit 51, and the surplus power is output as the output power P1 of the FC unit 51. The same applies to the output power p2 of the FC stack 22 and the output power p3 of the FC stack 23.
　制御装置１０は、出力線１７から外部への供給電力を略一定の所定値に維持する制御を行う。例えば、制御装置１０は、出力線１７から電力変換装置１１に向けて出力される供給電力Ｐａ（＝Ｐｏ－Ｐｂ）が一定の目標値に維持されるように、ＦＣスタック２１，２２，２３（ＦＣプラットフォーム１，２，３）の発電及びＤＣ／ＤＣコンバータ１３の変換動作を制御する。Ｐｏは、出力点１６における電力である。Ｐｏは、ＦＣプラットフォーム１，２，３の各出力電力Ｐ１，Ｐ２，Ｐ３の和に等しい（Ｐｏ＝Ｐ１＋Ｐ２＋Ｐ３）。Ｐｂは、二次電池１４と出力線１７との間でやり取りされる電力である。 The control device 10 performs control to maintain the power supplied from the output line 17 to the outside at a substantially constant predetermined value. For example, the control device 10 controls the power generation of the FC stacks 21, 22, 23 ( FC platforms 1, 2, 3) and the conversion operation of the DC/DC converter 13 so that the supply power Pa (=Po-Pb) output from the output line 17 to the power conversion device 11 is maintained at a constant target value. Po is the power at the output point 16. Po is equal to the sum of the output powers P1, P2, P3 of the FC platforms 1, 2, 3 (Po=P1+P2+P3). Pb is the power exchanged between the secondary battery 14 and the output line 17.
　制御装置１０は、電力変換装置１１から外部装置１２に向けて出力される電力Ｐｃが目標値に追従するように、ＦＣスタック２１，２２，２３の発電及び電力変換装置１１の変換動作を制御してもよい。Ｐａ又はＰｃは、出力線１７から外部への供給電力の一例である。 The control device 10 may control the power generation of the FC stacks 21, 22, and 23 and the conversion operation of the power conversion device 11 so that the power Pc output from the power conversion device 11 to the external device 12 follows a target value. Pa or Pc is an example of power supplied from the output line 17 to the outside.
　制御装置１０は、出力線１７から外部への供給電力Ｐａが略一定値に維持された状態で、ＦＣスタック２１，２２，２３の各出力電力ｐ１，ｐ２，ｐ３を変化（より詳しくは、増減）させる制御（電力変動制御）を行ってもよい。供給電力Ｐａは、電圧センサ及び電流センサにより検出可能である。 The control device 10 may perform control (power fluctuation control) to change (more specifically, increase or decrease) the output power p1, p2, and p3 of the FC stacks 21, 22, and 23 while the supply power Pa from the output line 17 to the outside is maintained at a substantially constant value. The supply power Pa can be detected by a voltage sensor and a current sensor.
　制御装置１０は、例えば、ＦＣプラットフォーム１の昇圧コンバータ４２の動作電流（負荷電流）を増減することでＦＣスタック２１の負荷を増減させ、出力電力ｐ１を増減させる。同様に、制御装置１０は、ＦＣプラットフォーム２の昇圧コンバータ４２の動作電流（負荷電流）を増減することでＦＣスタック２２の負荷を増減させ、出力電力ｐ２を増減させる。制御装置１０は、ＦＣプラットフォーム３の昇圧コンバータ４２の動作電流（負荷電流）を増減することでＦＣスタック２３の負荷を増減させ、出力電力ｐ３を増減させる。 The control device 10, for example, increases or decreases the operating current (load current) of the boost converter 42 of the FC platform 1 to increase or decrease the load on the FC stack 21 and increase or decrease the output power p1. Similarly, the control device 10 increases or decreases the operating current (load current) of the boost converter 42 of the FC platform 2 to increase or decrease the load on the FC stack 22 and increase or decrease the output power p2. The control device 10 increases or decreases the operating current (load current) of the boost converter 42 of the FC platform 3 to increase or decrease the load on the FC stack 23 and increase or decrease the output power p3.
　制御装置１０が上記のような電力変動制御を行うことで、出力線１７から外部への供給電力Ｐａが略一定値に維持された状態で、複数のＦＣスタック２１，２２，２３の各出力電力ｐ１，ｐ２，ｐ３が増減する。これにより、出力線１７から外部への一定の電力供給が確保された状態で、複数のＦＣスタック２１，２２，２３のセル面内の湿度分布の偏りは、各出力電力ｐ１，ｐ２，ｐ３が常に一定に制御される場合に比べて、減少する。セル面内の湿度分布の偏りが減少することで、有効反応面積の低下による電流密度の上昇が抑制されるので、電流密度の上昇による電解質膜の劣化が抑制される。したがって、供給電力Ｐａが略一定値に維持された状態で各出力電力ｐ１，ｐ２，ｐ３を増減させる電力変動制御が制御装置１０により行われることで、略一定の電力供給が確保され、複数のＦＣスタック２１，２２，２３の劣化が抑制される。複数のＦＣスタック２１，２２，２３の劣化の抑制は、燃料電池発電装置１０１及び燃料電池発電システム２０１の耐久性の向上に貢献する。 By the control device 10 performing the power fluctuation control as described above, the output powers p1, p2, and p3 of the multiple FC stacks 21, 22, and 23 are increased or decreased while the power supply Pa from the output line 17 to the outside is maintained at an approximately constant value. As a result, while a constant power supply from the output line 17 to the outside is ensured, the humidity distribution deviation within the cell surface of the multiple FC stacks 21, 22, and 23 is reduced compared to the case where the output powers p1, p2, and p3 are always controlled to be constant. By reducing the humidity distribution deviation within the cell surface, the increase in current density due to the decrease in effective reaction area is suppressed, and deterioration of the electrolyte membrane due to the increase in current density is suppressed. Therefore, by the control device 10 performing the power fluctuation control to increase or decrease the output powers p1, p2, and p3 while the supply power Pa is maintained at an approximately constant value, an approximately constant power supply is ensured and deterioration of the multiple FC stacks 21, 22, and 23 is suppressed. Suppressing deterioration of the multiple FC stacks 21, 22, and 23 contributes to improving the durability of the fuel cell power generation device 101 and the fuel cell power generation system 201.
　燃料電池発電システム２０１又は燃料電池発電装置１０１は、複数のＦＣプラットフォームのそれぞれに対して設けられた複数の開閉器（この例では、開閉器６１，６２，６３）を備えてもよい。開閉器６１は、ＦＣスタック２１及び昇圧コンバータ４２と、出力線１７に接続される出力点１６との間の電力経路の遮断と接続を切り替える遮断器である。開閉器６２は、ＦＣスタック２２及び不図示の昇圧コンバータと、出力線１７に接続される出力点１６との間の電力経路の遮断と接続を切り替える遮断器である。開閉器６３は、ＦＣスタック２３及び不図示の昇圧コンバータと、出力線１７に接続される出力点１６との間の電力経路の遮断と接続を切り替える遮断器である。 The fuel cell power generation system 201 or the fuel cell power generation device 101 may include a plurality of switches (switches 61, 62, and 63 in this example) provided for each of a plurality of FC platforms. Switch 61 is a circuit breaker that switches between disconnection and connection of the power path between the FC stack 21 and boost converter 42, and the output point 16 connected to the output line 17. Switch 62 is a circuit breaker that switches between disconnection and connection of the power path between the FC stack 22 and boost converter (not shown), and the output point 16 connected to the output line 17. Switch 63 is a circuit breaker that switches between disconnection and connection of the power path between the FC stack 23 and boost converter (not shown), and the output point 16 connected to the output line 17.
　制御装置１０は、複数のＦＣスタック２１，２２，２３のうち、一部のＦＣスタックを他のＦＣスタックから開閉器６１，６２又は６３により切り離してもよい。当該一部のＦＣスタックが切り離された状態で、制御装置１０は、供給電力Ｐａが略一定値に維持されるように、当該他のＦＣスタックの出力電力を制御してもよい。これにより、供給電力Ｐａが略一定値に維持された状態で、当該一部のＦＣスタックの交換が容易になる。例えば、制御装置１０は、ＦＣスタック２１が開閉器６１によりＦＣスタック２２，２３から切り離された状態で、供給電力Ｐａが略一定値に維持されるように、他のＦＣスタック２２，２３の出力電力を制御してもよい。開閉器６１，６２，６３の開閉は、制御装置１０によって自動で切り替えられるが、手動で切り替えられてもよい。 The control device 10 may separate some of the FC stacks 21, 22, 23 from the other FC stacks by switches 61, 62, or 63. With the FC stacks separated, the control device 10 may control the output power of the other FC stacks so that the power supply Pa is maintained at a substantially constant value. This makes it easier to replace the FC stacks while the power supply Pa is maintained at a substantially constant value. For example, with the FC stack 21 separated from the FC stacks 22, 23 by switch 61, the control device 10 may control the output power of the other FC stacks 22, 23 so that the power supply Pa is maintained at a substantially constant value. The switches 61, 62, 63 are automatically switched on and off by the control device 10, but may also be switched manually.
　燃料電池発電装置１０１は、複数のＦＣプラットフォームのうち、一部のＦＣプラットフォームが動作中に残りのＦＣプラットフォームを運転停止して取り外せるように、配管を遮断する遮断弁、及び、配線を遮断する開閉器を備えてもよい。配管は、液体（冷却液、排水など）又は気体（空気、水素、排ガスなど）を伝達し、配線は、電力や信号を伝送する。配管を遮断する遮断弁として、空気入口遮断弁７７及び排空気出口遮断弁７８が例示される。配線を遮断する開閉器として、開閉器６１，６２，６３が例示される。 The fuel cell power generation system 101 may be equipped with shutoff valves for shutting off the piping and switches for shutting off the wiring so that some of the multiple FC platforms can be shut down and removed while the remaining FC platforms are in operation. The piping transmits liquids (coolant, wastewater, etc.) or gases (air, hydrogen, exhaust gas, etc.), and the wiring transmits power and signals. Examples of shutoff valves for shutting off the piping include the air inlet shutoff valve 77 and the exhaust air outlet shutoff valve 78. Examples of switches for shutting off the wiring include switches 61, 62, and 63.
　燃料電池発電装置１０１は、複数のＦＣプラットフォームの地絡を個別に検出する機能を備えてもよい。例えば、制御装置１０は、複数のＦＣプラットフォーム１，２，３のうち、対地間抵抗の低下もしくは地絡が検出されたＦＣプラットフォームを、開閉器６１，６２又は６３により切り離してもよい。 The fuel cell power generation system 101 may have a function for individually detecting ground faults in multiple FC platforms. For example, the control device 10 may use the switch 61, 62, or 63 to disconnect an FC platform among multiple FC platforms 1, 2, and 3 in which a drop in resistance to ground or a ground fault has been detected.
　二次電池１４の出力電圧と出力点１６での出力電圧とが略等しくなるように、直列に接続される複数の蓄電池１４１，…，１４ｎの数が調整されてもよい。これにより、ＤＣ／ＤＣコンバータ１３を削除して燃料電池発電装置１０１を小型化できる。 The number of the multiple storage batteries 14 1 , ..., 14 n connected in series may be adjusted so that the output voltage of the secondary battery 14 is approximately equal to the output voltage at the output point 16. This makes it possible to eliminate the DC/DC converter 13 and reduce the size of the fuel cell power generation device 101.
　外部装置１２の電力需要と燃料電池発電装置１０１の関係から、二次電池１４の容量を増加させるため、複数の蓄電池１４１，…，１４ｎを並列に接続してもよい。複数の蓄電池１４１，…，１４ｎの並列数は、出力線１７に共通接続される複数のＦＣプラットフォームの数よりも少ないのが好ましい。この場合、複数のＦＣプラットフォームの各出力電力ラインに個別に蓄電池を接続する場合に比べて、燃料電池発電装置１０１を小型化できる。 Depending on the relationship between the power demand of the external device 12 and the fuel cell power generation system 101, multiple storage batteries 14 1 , ..., 14 n may be connected in parallel to increase the capacity of the secondary battery 14. The number of parallel connections of the multiple storage batteries 14 1 , ..., 14 n is preferably smaller than the number of the multiple FC platforms commonly connected to the output line 17. In this case, the fuel cell power generation system 101 can be made smaller than when storage batteries are individually connected to the output power lines of the multiple FC platforms.
　このように、本実施形態によれば、定置用発電機、港湾荷役機械（クレーンなど）用電源、船用電源、鉄道用電源、建設用重機、土木作業用重機などの分野において、水素発電による電源の脱炭素化の課題を解決できる。水素発電には、水素燃焼式と燃料電池式があるが、一般的に燃料電池式の方が高効率である。燃料電池を多用途に適用する際に、それぞれのシステム開発に時間と労力を要する。本実施形態によれば、様々な用途に共通して使用できる安価で高効率なプラットフォームの開発という課題を解決できる。より詳しくは、様々な用途（定置用、クレーン用、船舶用、鉄道用、建機用等）に適用するために、共通となる部分をＦＣプラットフォームとして構築することで、各用途のシステム開発リソース（設計、エンジニアリングなど）を低減できる。各用途共通のプラットフォームを使用することで、ＦＣプラットフォームの量産効果が得られ、低価格化が実現する。 In this way, according to this embodiment, the problem of decarbonizing power sources through hydrogen power generation can be solved in fields such as stationary generators, power sources for port loading and unloading machines (such as cranes), power sources for ships, power sources for railways, heavy construction machinery, and heavy civil engineering machinery. There are hydrogen combustion and fuel cell types of hydrogen power generation, but the fuel cell type is generally more efficient. When applying fuel cells to multiple applications, it takes time and effort to develop each system. According to this embodiment, the problem of developing an inexpensive and highly efficient platform that can be used in common for various applications can be solved. More specifically, in order to apply it to various applications (stationary, crane, ship, railway, construction machinery, etc.), the common parts are constructed as an FC platform, thereby reducing the system development resources (design, engineering, etc.) for each application. By using a platform common to each application, the mass production effect of the FC platform can be obtained, and the price can be reduced.
　また、本実施形態によれば、２つの冷却系（第１冷却系統３６及び第２冷却系統９０）について、適用するシステムや設置場所などに応じて冷却系の個別エンジニアリングが不要となる。より詳しくは、２つの冷却系のうち一方又は両方の中間熱交換器をＦＣプラットフォーム内に設置することで冷却系の個別エンジニアリングが不要になる。 Furthermore, according to this embodiment, for the two cooling systems (first cooling system 36 and second cooling system 90), individual engineering of the cooling systems is not required depending on the system to which they are applied, the installation location, etc. More specifically, by installing one or both intermediate heat exchangers of the two cooling systems within the FC platform, individual engineering of the cooling systems is not required.
　また、本実施形態によれば、ＦＣプラットフォームの並列化により、拡張性向上及び高出力対応を実現できる。補機を組み込んだＦＣプラットフォームを構築することで、複数のＦＣプラットフォームを容易に並列化でき、拡張性向上及び高出力対応の実現が容易になる。 Furthermore, according to this embodiment, the parallelization of FC platforms can improve scalability and support high output. By constructing an FC platform that incorporates auxiliary equipment, multiple FC platforms can be easily parallelized, making it easier to improve scalability and support high output.
　また、本実施形態によれば、複数のＦＣプラットフォームをそれぞれ独立に切り離すことができ、運搬などの取り扱いが容易になるので、例えば、メンテナンスが容易化される。例えば、システム故障時にはＦＣプラットフォームごとの交換によって、システムの停止期間が短縮し、システムの稼働率が向上する。システム故障時には現地で修復するのではなく、ＦＣプラットフォームを工場に引き取り、工場で修復することで、現地修復にかかるコストが低減する。工場引き取り期間は代替えのＦＣプラットフォームを入れ替えることで、システムの稼働率が向上する。 Furthermore, according to this embodiment, multiple FC platforms can be separated independently, facilitating handling such as transportation, which, for example, facilitates maintenance. For example, in the event of a system failure, the system downtime can be shortened by replacing each FC platform, improving the system's operating rate. In the event of a system failure, rather than repairing the system on-site, the FC platform can be returned to the factory and repaired there, reducing the cost of on-site repair. During the factory return period, a replacement FC platform can be replaced, improving the system's operating rate.
　以上の通り、実施形態を説明したが、上記実施形態は、例として提示したものであり、上記実施形態により本発明が限定されるものではない。上記実施形態は、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、種々の組み合わせ、省略、置き換え、変更などを行うことが可能である。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共に、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 the embodiments have been described above, they are presented as examples, and the present invention is not limited to the above embodiments. The above embodiments can be implemented in various other forms, and various combinations, omissions, substitutions, modifications, etc. can be made without departing from the gist of the invention. These embodiments and their variations are included in the scope and gist of the invention, and are included in the scope of the invention and its equivalents described in the claims.
　例えば、図１では、窒素を供給するパージ系統３０が水素を供給する燃料系統１８に合流する箇所は、燃料系統１８がＦＣスタック２１，２２，２３に向けて分岐した後の系統であるが、分岐する前の系統でもよい。 For example, in FIG. 1, the point where the purge system 30 that supplies nitrogen merges with the fuel system 18 that supplies hydrogen is after the fuel system 18 branches off toward the FC stacks 21, 22, and 23, but it may be before the branching.

The fuel cell power generation apparatus according to the second embodiment also includes an auxiliary unit attached to an upper portion of a second side of the pallet opposite the first side in the first direction and used when operating the fuel cells.

For example, the heat exchanger 421, the heat exchanger 422, the reservoir tank 423, the reservoir tank 424, the ion exchanger 425, and the like may be provided on the top surface of the frame 420f, so that the devices are provided outside the frame 420f. In that case, even if they are outside frame 420f, they are provided inside frame 420f in plan view. By providing heat exchanger 421, heat exchanger 422, reservoir tank 423, reservoir tank 424, ion exchanger 425, air filter 426, electric circuit box 427, and coolant pump 428 in the space inside frame 420f, these devices can be protected from external mechanical shocks.
　熱交換器４２１は、枠４２０ｆの内側における下側（－Ｚ側）かつ－Ｘ側に設けられる。熱交換器４２１は、補機ユニット４２０に設けられる補機の中でも重量の重い機器である。また、燃料電池ユニット４１０と補機ユニット４２０とを重量を比較すると、燃料電池ユニット４１０の方が重い。したがって、補機ユニット４２０において重量の重い熱交換器４２１を、枠４２０ｆの内側における下側（－Ｚ側）かつ－Ｘ側に設けることにより、燃料電池発電装置４０１の全体の重量バランスをよくできる。 The heat exchanger 421 is provided on the lower side (-Z side) and -X side inside the frame 420f. The heat exchanger 421 is the heaviest of the accessories provided in the accessory unit 420. Furthermore, when comparing the weight of the fuel cell unit 410 and the accessory unit 420, the fuel cell unit 410 is heavier. Therefore, by providing the heavier heat exchanger 421 in the accessory unit 420 on the lower side (-Z side) and -X side inside the frame 420f, the overall weight balance of the fuel cell power generation device 401 can be improved.
　エアフィルタ４２６及び電気回路ボックス４２７のそれぞれは、熱交換器４２１より高い位置に設けられる。エアフィルタ４２６のそれぞれが、熱交換器４２１より高い位置に設けられることにより、冷却液ＣＬ１が漏れたときにエアフィルタ４２６に冷却液ＣＬ１が流入することを防止できる。また、電気回路ボックス４２７が、熱交換器４２１より高い位置に設けられることにより、冷却液ＣＬ１が漏れたときに、冷却液ＣＬ１が電気回路ボックス４２７にかかることを防止できる。冷却液ＣＬ１が電気回路ボックス４２７にかかることを防止することにより、電気回路ボックス４２７における漏電を防止できる。 The air filter 426 and the electric circuit box 427 are each provided at a higher position than the heat exchanger 421. By providing the air filters 426 at a higher position than the heat exchanger 421, it is possible to prevent the coolant CL1 from flowing into the air filter 426 when the coolant CL1 leaks. Also, by providing the electric circuit box 427 at a higher position than the heat exchanger 421, it is possible to prevent the coolant CL1 from getting on the electric circuit box 427 when the coolant CL1 leaks. By preventing the coolant CL1 from getting on the electric circuit box 427, it is possible to prevent electric leakage in the electric circuit box 427.
　さらに、エアフィルタ４２６及び電気回路ボックス４２７のそれぞれは、平面視で熱交換器４２２、イオン交換器４２５、リザーバータンク４２３及びリザーバータンク４２４のそれぞれと重ならない位置に設けられる。 Furthermore, the air filter 426 and the electrical circuit box 427 are positioned so as not to overlap the heat exchanger 422, the ion exchanger 425, the reservoir tank 423, and the reservoir tank 424 in a plan view.
　エアフィルタ４２６が、平面視で熱交換器４２２、イオン交換器４２５、リザーバータンク４２３及びリザーバータンク４２４のそれぞれと重ならない位置に設けられることにより、冷却液ＣＬ１又は冷却液ＣＬ２が漏れたときにエアフィルタ４２６への冷却液ＣＬ１又は冷却液ＣＬ２の流入を防止できる。 By providing the air filter 426 in a position that does not overlap with the heat exchanger 422, the ion exchanger 425, the reservoir tank 423, and the reservoir tank 424 in a plan view, it is possible to prevent the coolant CL1 or the coolant CL2 from flowing into the air filter 426 when the coolant CL1 or the coolant CL2 leaks.
　電気回路ボックス４２７が、平面視で熱交換器４２２、イオン交換器４２５、リザーバータンク４２３及びリザーバータンク４２４のそれぞれと重ならない位置に設けられることにより、冷却液ＣＬ１又は冷却液ＣＬ２が漏れたときに、冷却液ＣＬ１又は冷却液ＣＬ２が電気回路ボックス４２７にかかることを防止できる。冷却液ＣＬ１又は冷却液ＣＬ２が電気回路ボックス４２７にかかることを防止することにより、電気回路ボックス４２７における漏電を防止できる。 By providing the electric circuit box 427 at a position that does not overlap with the heat exchanger 422, the ion exchanger 425, the reservoir tank 423, and the reservoir tank 424 in a plan view, it is possible to prevent the coolant CL1 or the coolant CL2 from getting on the electric circuit box 427 when the coolant CL1 or the coolant CL2 leaks. By preventing the coolant CL1 or the coolant CL2 from getting on the electric circuit box 427, it is possible to prevent electric leakage in the electric circuit box 427.
　イオン交換器４２５は、エアフィルタ４２６の上方に設けられている。一方、イオン交換器における冷却液ＣＬ１が流れる配管が接続される位置は、平面視で、エアフィルタ４２６の吸入口に重ならない位置に設けられる。イオン交換器４２５における冷却液ＣＬ１が流れる配管が接続される位置が、平面視で、エアフィルタ４２６の吸入口に重ならない位置に設けられることにより、冷却液ＣＬ１が漏れたときに、エアフィルタ４２６への冷却液ＣＬ１の流入を防止できる。 The ion exchanger 425 is provided above the air filter 426. Meanwhile, the position where the piping through which the coolant CL1 flows in the ion exchanger is connected is provided at a position that does not overlap the intake port of the air filter 426 in a plan view. By providing the position where the piping through which the coolant CL1 flows in the ion exchanger 425 is connected at a position that does not overlap the intake port of the air filter 426 in a plan view, it is possible to prevent the coolant CL1 from flowing into the air filter 426 when the coolant CL1 leaks.
　燃料電池ユニット４１０から回収される冷却液ＣＬ１Ｈの温度は、７０℃程度になる。したがって、電気回路ボックス４２７に収納された電気回路等が高温にならないようにするために、電気回路ボックス４２７は、冷却液ＣＬ１Ｈが通る経路から離すように設けてもよい。補機ユニット４２０は、熱交換器４２１を補機ユニット４２０の下側、電気回路ボックス４２７を補機ユニット４２０の上側に備えることにより、冷却液ＣＬ１Ｈによる電気回路ボックス４２７の温度上昇を抑制できる。 The temperature of the coolant CL1H recovered from the fuel cell unit 410 is about 70°C. Therefore, to prevent the electric circuits housed in the electric circuit box 427 from becoming too hot, the electric circuit box 427 may be located away from the path through which the coolant CL1H passes. The auxiliary unit 420 can suppress the temperature rise of the electric circuit box 427 due to the coolant CL1H by providing the heat exchanger 421 on the lower side of the auxiliary unit 420 and the electric circuit box 427 on the upper side of the auxiliary unit 420.
　　なお、補機ユニット４２０が備える補機は、熱交換器４２１、熱交換器４２２、リザーバータンク４２３、リザーバータンク４２４、イオン交換器４２５、エアフィルタ４２６、電気回路ボックス４２７、冷却液ポンプ４２８及び気液分離器４２９に限らない。補機ユニット４２０が備える補機は、熱交換器４２１、熱交換器４２２、リザーバータンク４２３、リザーバータンク４２４、イオン交換器４２５、エアフィルタ４２６、電気回路ボックス４２７、冷却液ポンプ４２８及び気液分離器４２９の中から適宜組み合わせてもよい。補機ユニット４２０が備える補機は、上記の機器のすべてを備えている場合に限らず、一部を備えていてもよい。例えば、エアフィルタ４２６は、補機ユニットと別に備えるようにしてもよい。また、補機ユニットは、上記以外の機器を備えていてもよい。 The auxiliary equipment provided in the auxiliary equipment unit 420 is not limited to the heat exchanger 421, the heat exchanger 422, the reservoir tank 423, the reservoir tank 424, the ion exchanger 425, the air filter 426, the electric circuit box 427, the coolant pump 428, and the gas-liquid separator 429. The auxiliary equipment provided in the auxiliary equipment unit 420 may be an appropriate combination of the heat exchanger 421, the heat exchanger 422, the reservoir tank 423, the reservoir tank 424, the ion exchanger 425, the air filter 426, the electric circuit box 427, the coolant pump 428, and the gas-liquid separator 429. The auxiliary equipment provided in the auxiliary equipment unit 420 is not limited to the case where all of the above devices are provided, and may include only some of them. For example, the air filter 426 may be provided separately from the auxiliary equipment unit. The auxiliary equipment unit may also include devices other than those described above.
　［パレット４３０］
　図８は、第２実施形態に係る燃料電池発電装置の一例である燃料電池発電装置４０１におけるパレット４３０の斜視図である。パレット４３０は、燃料電池ユニット４１０及び補機ユニット４２０を載置して保持する。パレット４３０は、フォークリフトにより燃料電池発電装置４０１を運搬する際に、フォークリフトのフォークが挿入される。フォークは、運搬機器の載荷部材の一例である。なお、運搬機器は、フォークリフトに限らず、燃料電池発電装置４０１を運搬可能な機器、例えば、荷役車両、クレーン、ハンドリフタ等であればよい。また、載荷部材は、フォークに限らず、燃料電池発電装置４０１を載せることができる部材であればよい。 [Palette 430]
8 is a perspective view of a pallet 430 in a fuel cell power generation apparatus 401, which is an example of a fuel cell power generation apparatus according to the second embodiment. The pallet 430 holds the fuel cell unit 410 and the auxiliary unit 420. When the fuel cell power generation apparatus 401 is transported by a forklift, the forks of the forklift are inserted into the pallet 430. The forks are an example of a loading member of a transport device. Note that the transport device is not limited to a forklift, but may be any device capable of transporting the fuel cell power generation apparatus 401, such as a cargo handling vehicle, a crane, or a hand lifter. Furthermore, the loading member is not limited to a fork, but may be any member on which the fuel cell power generation apparatus 401 can be placed.
　パレット４３０は、Ｘ軸方向に長手方向を有する。パレット４３０は、枠部材の一例として角パイプ４３１及び角パイプ４３２を備える。また、パレット４３０は、角パイプ４３１と角パイプ４３２とを連結する連結部材４３３ａ、連結部材４３３ｂ及び連結部材４３３ｃを備える。 Pallet 430 has a longitudinal direction in the X-axis direction. Pallet 430 includes square pipes 431 and 432 as an example of a frame member. Pallet 430 also includes connecting members 433a, 433b, and 433c that connect square pipes 431 and 432.
　　（角パイプ４３１）
　角パイプ４３１は、Ｘ軸方向に延びる角パイプである。角パイプ４３１は、＋Ｘ側の上部に、燃料電池ユニット４１０が載置される載置部４３１Ａを有する。また、角パイプ４３１は、－Ｘ側の上部に、補機ユニット４２０が載置される載置部４３１Ｂを有する。 (Square pipe 431)
The square pipe 431 is a square pipe extending in the X-axis direction. The square pipe 431 has a mounting portion 431A on which the fuel cell unit 410 is mounted at an upper portion on the +X side. The square pipe 431 also has a mounting portion 431B on which the auxiliary unit 420 is mounted at an upper portion on the -X side.
　燃料電池発電装置４０１が運搬される際に、矢印ＦＡに示す向きに、角パイプ４３１の＋Ｘ側からフォークリフトのフォークの一方が挿入される。 When the fuel cell power generation device 401 is transported, one of the forks of a forklift is inserted into the +X side of the square pipe 431 in the direction indicated by the arrow FA.
　角パイプ４３１は、＋Ｘ側に燃料電池ユニット４１０が載置される載置部４３１Ａを有する。燃料電池発電装置４０１において、燃料電池ユニット４１０は補機ユニット４２０より重いことから、燃料電池発電装置４０１を運搬する際には、角パイプ４３１の＋Ｘ側からフォークリフトのフォークを挿入するようにするとよい。角パイプ４３２についても同様である。 The square pipe 431 has a mounting section 431A on the +X side on which the fuel cell unit 410 is mounted. In the fuel cell power generation device 401, since the fuel cell unit 410 is heavier than the auxiliary unit 420, when transporting the fuel cell power generation device 401, it is advisable to insert the forks of a forklift from the +X side of the square pipe 431. The same applies to the square pipe 432.
　角パイプ４３１の構造についてより詳しく説明する。なお、角パイプ４３２は、角パイプ４３１と同様の構造を有することから、角パイプ４３２についての詳細な説明は省略して、角パイプ４３１の説明を参照することとする。 The structure of square pipe 431 will be explained in more detail. Note that since square pipe 432 has a similar structure to square pipe 431, a detailed explanation of square pipe 432 will be omitted and reference will be made to the explanation of square pipe 431.
　図９は、第２実施形態に係る燃料電池発電装置の一例である燃料電池発電装置４０１におけるパレット４３０が備える枠部材である角パイプ４３１の側面図である。 FIG. 9 is a side view of a square pipe 431, which is a frame member of a pallet 430 in a fuel cell power generation device 401, which is an example of a fuel cell power generation device according to the second embodiment.
　角パイプ４３１は、Ｘ軸方向に垂直なＹＺ平面における断面が矩形状である角パイプである。角パイプ４３１は、横板部４３１ａと、縦板部４３１ｂと、横板部４３１ｃと、縦板部４３１ｄと、を備える。角パイプ４３１の＋Ｘ側は、開放された状態になっている。言い換えると、角パイプ４３１は、＋Ｘ側に開放部４３１ｈ１（図８参照）を備える。同様に、角パイプ４３１の－Ｘ側は、開放された状態になっている。言い換えると、角パイプ４３１は、－Ｘ側に開放部４３１ｈ２（図８参照）を備える。 The square pipe 431 is a square pipe whose cross section in the YZ plane perpendicular to the X-axis direction is rectangular. The square pipe 431 has a horizontal plate portion 431a, a vertical plate portion 431b, a horizontal plate portion 431c, and a vertical plate portion 431d. The +X side of the square pipe 431 is open. In other words, the square pipe 431 has an opening portion 431h1 (see FIG. 8) on the +X side. Similarly, the -X side of the square pipe 431 is open. In other words, the square pipe 431 has an opening portion 431h2 (see FIG. 8) on the -X side.
　横板部４３１ａは、ＸＹ平面に平行であってＸ軸方向に長手方向を有する板状の部材である。横板部４３１ａは、＋Ｚ側に上面４３１ａＡと－Ｚ側に内面４３１ａＢを有する。角パイプ４３１は、上面４３１ａＡに載置部４３１Ａ及び載置部４３１Ｂを有する。フォークリフトのフォークは、燃料電池発電装置４０１を運搬する際に、内面４３１ａＢに接触する。 The horizontal plate portion 431a is a plate-like member parallel to the XY plane and with its longitudinal direction in the X-axis direction. The horizontal plate portion 431a has an upper surface 431aA on the +Z side and an inner surface 431aB on the -Z side. The square pipe 431 has mounting portions 431A and 431B on the upper surface 431aA. The forks of a forklift come into contact with the inner surface 431aB when transporting the fuel cell power generation device 401.
　縦板部４３１ｂは、ＺＸ平面に平行であってＸ軸方向に長手方向を有する板状の部材である。縦板部４３１ｂは、横板部４３１ａにおける＋Ｙ側の端部から－Ｚ側に延びて設けられる。縦板部４３１ｂの－Ｚ側は、横板部４３１ｃの＋Ｙ側と接続する。 The vertical plate portion 431b is a plate-like member that is parallel to the ZX plane and has a longitudinal direction in the X-axis direction. The vertical plate portion 431b extends from the +Y side end of the horizontal plate portion 431a to the -Z side. The -Z side of the vertical plate portion 431b connects to the +Y side of the horizontal plate portion 431c.
　横板部４３１ｃは、ＸＹ平面に平行であってＸ軸方向に長手方向を有する板状の部材である。横板部４３１ｃは、横板部４３１ａの－Ｚ側に離隔して設けられる。 The horizontal plate portion 431c is a plate-shaped member that is parallel to the XY plane and has a longitudinal direction in the X-axis direction. The horizontal plate portion 431c is provided at a distance from the horizontal plate portion 431a on the -Z side.
　縦板部４３１ｄは、ＺＸ平面に平行であってＸ軸方向に長手方向を有する板状の部材である。縦板部４３１ｄは、横板部４３１ａにおける－Ｙ側の端部から－Ｚ側に延びて設けられる。縦板部４３１ｄの－Ｚ側は、横板部４３１ｃの－Ｙ側と接続する。縦板部４３１ｄは、縦板部４３１ｂの－Ｙ側に離隔して設けられる。 The vertical plate portion 431d is a plate-like member that is parallel to the ZX plane and has a longitudinal direction in the X-axis direction. The vertical plate portion 431d extends from the -Y side end of the horizontal plate portion 431a to the -Z side. The -Z side of the vertical plate portion 431d is connected to the -Y side of the horizontal plate portion 431c. The vertical plate portion 431d is spaced apart from the -Y side of the vertical plate portion 431b.
　なお、縦板部４３１ｂ及び縦板部４３１ｄは、燃料電池発電装置４０１をフォークリフトで運搬する際に、フォークが横方向（Ｙ軸方向）にずれて、フォークから燃料電池発電装置４０１がはずれることを防止する。 In addition, the vertical plate portions 431b and 431d prevent the forks from shifting horizontally (Y-axis direction) and causing the fuel cell power generation device 401 to come off the forks when the fuel cell power generation device 401 is transported by a forklift.
　角パイプ４３１は、内部に、横板部４３１ａ、縦板部４３１ｂ、横板部４３１ｃ及び縦板部４３１ｄに囲まれた空間４３１Ｓを有する。上述のように、空間４３１Ｓは、＋Ｘ側及び－Ｘ側に開放している。空間４３１Ｓには、角パイプ４３１の＋Ｘ側からフォークリフトのフォークの一方が挿入される。図１０は、第２実施形態に係る燃料電池発電装置の一例である燃料電池発電装置４０１におけるパレット４３０が備える枠部材である角パイプ４３１にフォークＦが挿入された状態を示す図である。図１０において、角パイプ４３１は断面図で示す。 The square pipe 431 has a space 431S inside, surrounded by horizontal plate portion 431a, vertical plate portion 431b, horizontal plate portion 431c, and vertical plate portion 431d. As described above, the space 431S is open to the +X side and the -X side. One of the forks of a forklift is inserted into the space 431S from the +X side of the square pipe 431. Figure 10 is a diagram showing a state in which a fork F is inserted into the square pipe 431, which is a frame member of a pallet 430 in a fuel cell power generation device 401, which is an example of a fuel cell power generation device according to the second embodiment. In Figure 10, the square pipe 431 is shown in cross section.
　角パイプ４３１は、内部の空間４３１ＳにフォークリフトのフォークＦが挿入される。フォークＦが空間４３１Ｓに挿入できるように、空間４３１ＳのＹ軸方向の幅Ｗと、Ｚ軸方向の高さＨは定められる。より具体的には、フォークＦの形状は、運搬する対象物の重量等により定まることから、燃料電池発電装置４０１を運搬するのに適するフォークＦの幅より幅Ｗを広くし、フォークＦの高さより高さＨを高くする。例えば、空間４３１Ｓの幅Ｗは、フォークＦの幅より１．１から１．３倍程度の幅にする。また、例えば、空間４３１Ｓの高さＨは、フォークＦの高さより１．５から３．５倍程度の高さにする。 The square pipe 431 has an internal space 431S into which the fork F of a forklift is inserted. The width W in the Y-axis direction and the height H in the Z-axis direction of the space 431S are determined so that the fork F can be inserted into the space 431S. More specifically, since the shape of the fork F is determined by factors such as the weight of the object to be transported, the width W is made wider than the width of the fork F suitable for transporting the fuel cell power generation device 401, and the height H is made higher than the height of the fork F. For example, the width W of the space 431S is about 1.1 to 1.3 times the width of the fork F. Also, for example, the height H of the space 431S is about 1.5 to 3.5 times the height of the fork F.
　また、図１０に示す例のように、フォークＦの長さが角パイプ４３１の長さＬより長い場合もある。したがって、空間４３１Ｓは、角パイプ４３１の長手方向（Ｘ軸方向）にわたって形成されるようにしてもよい。また、少なくとも燃料電池発電装置４０１の運搬時には、角パイプ４３１は、内面４３１ａＢに突起等を設けない構成にする。言い換えると、内面４３１ａＢは、平坦に形成される。なお、縦板部４３１ｂ、横板部４３１ｃ及び縦板部４３１ｄのそれぞれの内面についても、少なくとも燃料電池発電装置４０１の運搬時に、突起等を設けない構成にすることが望ましい。また、縦板部４３１ｂ、横板部４３１ｃ及び縦板部４３１ｄのそれぞれの内面について突起等を設ける場合、少なくとも燃料電池発電装置４０１の運搬時に、フォークＦが挿入できるような寸法にすることが望ましい。角パイプ４３２についても同様である。 Also, as shown in the example of FIG. 10, the length of the fork F may be longer than the length L of the square pipe 431. Therefore, the space 431S may be formed along the longitudinal direction (X-axis direction) of the square pipe 431. Also, at least when the fuel cell power generation device 401 is transported, the square pipe 431 is configured so that no protrusions or the like are provided on the inner surface 431aB. In other words, the inner surface 431aB is formed flat. It is preferable that the inner surfaces of the vertical plate portion 431b, the horizontal plate portion 431c, and the vertical plate portion 431d are also configured so that no protrusions or the like are provided, at least when the fuel cell power generation device 401 is transported. Also, when protrusions or the like are provided on the inner surfaces of the vertical plate portion 431b, the horizontal plate portion 431c, and the vertical plate portion 431d, it is preferable that the dimensions are such that the fork F can be inserted at least when the fuel cell power generation device 401 is transported. The same applies to the square pipe 432.
　例えば、角パイプ４３１の外面に突起等を設ける場合は、角パイプ４３１の外面に溶接等により突起等を取り付けるようにして、角パイプ４３１の内側に突起等がないようにする。なお、燃料電池発電装置４０１を運搬しないときは、角パイプ４３１の内側に突起等があってもよい。 For example, if protrusions or the like are provided on the outer surface of the square pipe 431, the protrusions or the like are attached to the outer surface of the square pipe 431 by welding or the like so that there are no protrusions or the like on the inside of the square pipe 431. Note that when the fuel cell power generation device 401 is not being transported, there may be protrusions or the like on the inside of the square pipe 431.
　上述のように、角パイプ４３１が有する空間４３１Ｓは、＋Ｘ側からフォークリフトのフォークＦが挿入されるように形成されている。言い換えると、角パイプ４３１が有する空間４３１Ｓは、フォークリフトのフォークＦが＋Ｘ側から挿入される際に、角パイプ４３１に干渉しないように、フォークリフトのフォークＦより大きい空間となっている。 As described above, the space 431S of the square pipe 431 is formed so that the forks F of the forklift are inserted from the +X side. In other words, the space 431S of the square pipe 431 is larger than the forks F of the forklift so that the forks F do not interfere with the square pipe 431 when they are inserted from the +X side.
　なお、燃料電池発電装置４０１を設置後など、燃料電池発電装置４０１を運搬していないときは、開放部４３１ｈ１及び開放部４３１ｈ２をカバー等により塞いでもよい。 In addition, when the fuel cell power generation device 401 is not being transported, such as after installation, the openings 431h1 and 431h2 may be covered with a cover or the like.
　また、角パイプ４３１において、空間４３１Ｓは、フォークが挿入できれば、角パイプ４３１を貫通していなくてもよい。例えば、空間４３１Ｓは、フォークが挿入できれば、Ｘ軸方向の途中まで形成されているような形態でもよい。言い換えると、角パイプ４３１は、開放部４３１ｈ１を備えて、開放部４３１ｈ２を備えず、角パイプ４３１の－Ｘ側は、塞がれていてもよい。角パイプ４３２についても同様である。 Also, in the square pipe 431, the space 431S does not have to penetrate the square pipe 431 as long as a fork can be inserted therein. For example, the space 431S may be formed partway in the X-axis direction as long as a fork can be inserted therein. In other words, the square pipe 431 may have an open portion 431h1 but no open portion 431h2, and the -X side of the square pipe 431 may be blocked. The same applies to the square pipe 432.
　　（角パイプ４３２）
　角パイプ４３２は、Ｘ軸方向に延びる角パイプである。角パイプ４３２は、角パイプ４３１からＹ軸方向の－Ｙ側に離隔して設けられる。角パイプ４３２は、＋Ｘ側の上部に、燃料電池ユニット４１０が載置される載置部４３２Ａを有する。また、角パイプ４３２は、－Ｘ側の上部に、補機ユニット４２０が載置される載置部４３２Ｂを有する。 (Square pipe 432)
The square pipe 432 is a square pipe extending in the X-axis direction. The square pipe 432 is provided at a distance from the square pipe 431 on the -Y side in the Y-axis direction. The square pipe 432 has a mounting portion 432A on which the fuel cell unit 410 is mounted at an upper portion on the +X side. The square pipe 432 also has a mounting portion 432B on which the auxiliary unit 420 is mounted at an upper portion on the -X side.
　燃料電池発電装置４０１が運搬される際に、矢印ＦＡに示す向きに、角パイプ４３２の＋Ｘ側からフォークリフトのフォークの他方が挿入される。 When the fuel cell power generation device 401 is transported, the other fork of the forklift is inserted into the +X side of the square pipe 432 in the direction indicated by the arrow FA.
　なお、角パイプ４３１において説明したように、角パイプ４３２は、＋Ｘ側に開放部４３２ｈ１（図８参照）及び－Ｘ側に開放部４３２ｈ２（図８参照）を備える。また、角パイプ４３２は、内部に空間４３２Ｓを有する。また、燃料電池発電装置４０１を設置後など、燃料電池発電装置４０１を運搬していないときは、開放部４３２ｈ１及び開放部４３２ｈ２をカバー等により塞いでもよい。 As explained for the square pipe 431, the square pipe 432 has an opening 432h1 (see FIG. 8) on the +X side and an opening 432h2 (see FIG. 8) on the -X side. The square pipe 432 also has a space 432S inside. After the fuel cell power generation device 401 is installed, or when the fuel cell power generation device 401 is not being transported, the openings 432h1 and 432h2 may be covered with a cover or the like.

From another perspective, the fuel cell power generation system 1302 includes the mobile stand 1330 below the pallet 430 in the fuel cell power generation system 1101 shown in FIG. 11.
　燃料電池発電装置１３０２は、移動用架台１３３５として、Ｘ軸方向から運搬機器の載荷部材を挿入できるパレット４３０と、Ｙ軸方向から運搬機器の載荷部材を挿入できる移動用架台１３３０と、を備える。燃料電池発電装置１３０２は、移動用架台１３３５として、パレット４３０と移動用架台１３３０とを備えることにより、Ｙ軸方向からも運搬機器の載荷部材を挿入できる。 The fuel cell power generation system 1302 is provided with a pallet 430 as a mobile stand 1335 into which the load members of the transport equipment can be inserted from the X-axis direction, and a mobile stand 1330 into which the load members of the transport equipment can be inserted from the Y-axis direction.

　例えば、燃料電池発電装置４０１は、Ｘ軸方向から運搬機器の載荷部材を挿入できるが、Ｙ軸方向から運搬機器の載荷部材を挿入できない。燃料電池発電装置４０１において、移動用架台を２段にすることにより、Ｙ軸方向からも運搬機器の載荷部材を挿入できる。 For example, the fuel cell power generation device 401 allows the loading members of the transport equipment to be inserted from the X-axis direction, but does not allow the loading members of the transport equipment to be inserted from the Y-axis direction. In the fuel cell power generation device 401, by making the mobile platform two-tiered, the loading members of the transport equipment can be inserted from the Y-axis direction as well.

　熱交換器２１２１は、燃料電池発電装置５０１における熱交換器５２１と同様の機能、構成を有することから、燃料電池発電装置５０１における熱交換器５２１の説明を参照することとして、熱交換器２１２１の詳細な説明についてここでは省略する。熱交換器２１２２、リザーバータンク２１２３、リザーバータンク２１２４、イオン交換器２１２５、エアフィルタ２１２６、電気回路ボックス２１２７、補機ユニット２１２０が備える冷却液ポンプ及び補機ユニット２１２０が備える気液分離器のそれぞれについても同様である。また、動力配線端子台２１４１、信号配線端子台２１４２、電源配線端子台２１４３及び接地配線端子台２１４４のそれぞれについても同様である。 Since the heat exchanger 2121 has the same function and configuration as the heat exchanger 521 in the fuel cell power generation system 501, the description of the heat exchanger 521 in the fuel cell power generation system 501 should be referred to, and a detailed description of the heat exchanger 2121 will be omitted here.

The same applies to the following bar materials. The bar material is not limited to steel sections with an L-shaped cross section, but may be steel sections with a C-shaped or U-shaped cross section, round bars, square bars, etc.
　棒材２１２０ｆ１における＋Ｙ側の端部は、棒材２１２０ｆ２における＋Ｘ側の端部に接続される。棒材２１２０ｆ１における－Ｙ側の端部は、棒材２１２０ｆ４における＋Ｘ側の端部に接続される。棒材２１２０ｆ３における＋Ｙ側の端部は、棒材２１２０ｆ２における－Ｘ側の端部に接続される。棒材２１２０ｆ３における－Ｙ側の端部は、棒材２１２０ｆ４における－Ｘ側の端部に接続される。棒材２１２０ｆ１、棒材２１２０ｆ２、棒材２１２０ｆ３及び棒材２１２０ｆ４は、平面視で、すなわち、＋Ｚ側からＺ軸方向に沿って見たときに、矩形状となる。枠体２１２０ｆは、棒材２１２０ｆ１と棒材２１２０ｆ３とを接続する連結部材２１２０ｆｍ１を備える。また、枠体２１２０ｆは、棒材２１２０ｆ１と棒材２１２０ｆ３とを接続する連結部材２１２０ｆｍ１と、棒材２１２０ｆ２とを接続する連結部材２１２０ｆｍ２を備える。 The +Y end of bar 2120f1 is connected to the +X end of bar 2120f2.

The frame 2120f is fixed to the pallet 2130 with nine bolts BT2.
　枠体２１２０ｆは、パレット２１３０に９本のボルトＢＴ２により固定されているが、５本以上のボルトＢＴ２で固定されればよい。言い換えると、補機フレームの一例である枠体２１２０ｆは、５点以上でパレット１３０に固定されればよい。枠体２１２０ｆを４点以下でパレット２１３０に固定しても十分固定されない場合があることから、枠体２１２０ｆは、５点以上でパレット２１３０に固定されるとよい。 The frame 2120f is fixed to the pallet 2130 with nine bolts BT2, but five or more bolts BT2 may be used. In other words, the frame 2120f, which is an example of an accessory frame, may be fixed to the pallet 130 at five or more points. Since fixing the frame 2120f to the pallet 2130 at four or fewer points may not be sufficient, it is preferable that the frame 2120f be fixed to the pallet 2130 at five or more points.
　また、枠体２１２０ｆは、Ｚ軸方向に沿って延びる棒材２１２０ｆ５、棒材２１２０ｆ６、棒材２１２０ｆ７及び棒材２１２０ｆ８を備える。棒材２１２０ｆ５における－Ｚ側の端部は、棒材２１２０ｆ１と棒材２１２０ｆ４とが結合する角に接続する。棒材２１２０ｆ６における－Ｚ側の端部は、棒材２１２０ｆ１と棒材２１２０ｆ２とが結合する角に接続する。棒材２１２０ｆ７における－Ｚ側の端部は、棒材２１２０ｆ２と棒材２１２０ｆ３とが結合する角に接続する。棒材２１２０ｆ８における－Ｚ側の端部は、棒材２１２０ｆ３と棒材２１２０ｆ４とが結合する角に接続する。 Furthermore, frame 2120f includes bars 2120f5, 2120f6, 2120f7, and 2120f8 extending along the Z-axis direction.

　棒材２１２０ｆ５及び棒材２１２０ｆ８のそれぞれは、棒材２１２０ｆ６及び棒材２１２０ｆ７のそれぞれより長い。 Bar material 2120f5 and bar material 2120f8 are each longer than bar material 2120f6 and bar material 2120f7.
　さらに、枠体２１２０ｆは、＋Ｚ側に、棒材２１２０ｆａ、棒材２１２０ｆｂ、棒材２１２０ｆｃ及び棒材２１２０ｆｄを備える。棒材２１２０ｆａ及び棒材２１２０ｆｃのそれぞれは、Ｙ軸方向に沿って延びる。棒材２１２０ｆｃは、棒材２１２０ｆａからＸ軸方向に沿って－Ｘ側に離隔して設けられる。棒材２１２０ｆｂ及び棒材２１２０ｆｄのそれぞれは、Ｘ軸方向に沿って延びる。棒材２１２０ｆｄは、平面視で棒材２１２０ｆｃからＹ軸方向に沿って－Ｙ側に離隔して設けられる。 Furthermore, frame 2120f is provided with rods 2120fa, 2120fb, 2120fc, and 2120fd on the +Z side.

Each of rods 2120fb and 2120fd extends along the X-axis direction. Rod 2120fd is spaced apart from rod 2120fc along the Y-axis direction on the -Y side in a plan view.
　棒材２１２０ｆａにおける＋Ｙ側の端部は、棒材２１２０ｆｂにおける＋Ｘ側の端部に接続される。棒材２１２０ｆａにおける－Ｙ側の端部は、棒材２１２０ｆ５における＋Ｚ側の端部と－Ｚ側の端部との間に接続される。棒材２１２０ｆｃにおける＋Ｙ側の端部は、棒材２１２０ｆｂにおける－Ｘ側の端部に接続される。棒材２１２０ｆｃにおける－Ｙ側の端部は、棒材２１２０ｆ８における＋Ｚ側の端部と－Ｚ側の端部との間に接続される。棒材２１２０ｆｄにおける＋Ｘ側の端部は、棒材２１２０ｆ５の＋Ｚ側の端部に接続される。棒材２１２０ｆｄにおける－Ｘ側の端部は、棒材２１２０ｆ８の＋Ｚ側の端部に接続される。 The +Y end of bar 2120fa is connected to the +X end of bar 2120fb. The -Y end of bar 2120fa is connected between the +Z end and the -Z end of bar 2120f5. The +Y end of bar 2120fc is connected to the -X end of bar 2120fb. The -Y end of bar 2120fc is connected between the +Z end and the -Z end of bar 2120f8. The +X end of bar 2120fd is connected to the +Z end of bar 2120f5. The -X end of bar 2120fd is connected to the +Z end of bar 2120f8.
　棒材２１２０ｆ６における＋Ｚ側の端部は、棒材２１２０ｆａと棒材２１２０ｆｂとが結合する角に接続する。棒材２１２０ｆ７における＋Ｚ側の端部は、棒材２１２０ｆｂと棒材２１２０ｆｃとが結合する角に接続する。 The +Z end of bar 2120f6 connects to the corner where bar 2120fa and bar 2120fb join. The +Z end of bar 2120f7 connects to the corner where bar 2120fb and bar 2120fc join.
　棒材２１２０ｆａ、棒材２１２０ｆｂ、棒材２１２０ｆｃ及び棒材２１２０ｆｄは、平面視で矩形状となる。また、棒材２１２０ｆａ、棒材２１２０ｆｂ、棒材２１２０ｆｃ及び棒材２１２０ｆｄは、平面視で、棒材２１２０ｆ１、棒材２１２０ｆ２、棒材２１２０ｆ３及び棒材２１２０ｆ４と重なるようになっている。 Bar material 2120fa, bar material 2120fb, bar material 2120fc, and bar material 2120fd are rectangular in plan view. Also, bar material 2120fa, bar material 2120fb, bar material 2120fc, and bar material 2120fd are configured to overlap bar material 2120f1, bar material 2120f2, bar material 2120f3, and bar material 2120f4 in plan view.
　枠体２１２０ｆは、棒材２１２０ｆａ、棒材２１２０ｆｂ及び棒材２１２０ｆｃにより画定される天面１２０ｆＳを有する。 The frame 2120f has a top surface 120fS defined by the bars 2120fa, 2120fb, and 2120fc.
　枠体２１２０ｆは、棒材２１２０ｆ５と棒材２１２０ｆ８とを接続して枠体２１２０ｆを補強する補強部材２１２０ｆｒを備える。熱交換器２１２１は、補強部材２１２０ｆｒで固定される。枠体２１２０ｆを補強する補強部材２１２０ｆｒで、補機の一つである熱交換器２１２１が固定されることにより、部品点数を低減できる。また、枠体２１２０ｆを補強する補強部材２１２０ｆｒで、補機の一つである熱交換器２１２１が固定されることにより、材料費や組み立て工数を低減できる。 The frame 2120f includes a reinforcing member 2120fr that connects the rods 2120f5 and 2120f8 to reinforce the frame 2120f. The heat exchanger 2121 is fixed by the reinforcing member 2120fr. The number of parts can be reduced by fixing the heat exchanger 2121, which is one of the auxiliary devices, to the reinforcing member 2120fr that reinforces the frame 2120f. Furthermore, the material costs and assembly man-hours can be reduced by fixing the heat exchanger 2121, which is one of the auxiliary devices, to the reinforcing member 2120fr that reinforces the frame 2120f.
　なお、枠体２１２０ｆは、枠体２１２０ｆが備える棒材の間を接続する連結部材１２０ｆｍを備えてもよい。また、連結部材１２０ｆｍは、枠体２１２０ｆが備える棒材と連結部材１２０ｆｍとの間を接続してもよい。枠体２１２０ｆが連結部材１２０ｆｍを備えることにより、枠体２１２０ｆの剛性を高めることができる。 The frame body 2120f may include a connecting member 120fm that connects between the rods included in the frame body 2120f. The connecting member 120fm may also connect between the rods included in the frame body 2120f and the connecting member 120fm. By including the connecting member 120fm in the frame body 2120f, the rigidity of the frame body 2120f can be increased.
　なお、棒材が構造部材の一例である。 The bar is an example of a structural member.
　次に、補機ユニット２１２０における補機の配置について説明する。図３８及び図３９のそれぞれは、第３Ａ実施形態に係る燃料電池発電装置の一例である燃料電池発電装置２００２における補機の配置について説明する図である。 Next, the arrangement of the auxiliaries in the auxiliary unit 2120 will be described. Each of Figures 38 and 39 is a diagram illustrating the arrangement of the auxiliaries in a fuel cell power generation system 2002, which is an example of a fuel cell power generation system according to embodiment 3A.
　補機ユニット２１２０における補機の中で、運用時にメンテナンスが必要となるメンテナンス部品、例えば、リザーバータンク２１２３、リザーバータンク２１２４、イオン交換器２１２５及びエアフィルタ２１２６は、枠体２１２０ｆにおける天面２１２０ｆＳに設けられる。言い換えると、補機フレームの一例である枠体２１２０ｆは、天面２１２０ｆＳにメンテナンス部品を備える。 Among the accessories in the accessory unit 2120, the maintenance parts that require maintenance during operation, such as the reservoir tank 2123, the reservoir tank 2124, the ion exchanger 2125, and the air filter 2126, are provided on the top surface 2120fS of the frame 2120f. In other words, the frame 2120f, which is an example of an accessory frame, has maintenance parts on the top surface 2120fS.
　燃料電池発電装置２００２における補機ユニット２１２０における＋Ｘ側の面は、例えば、作業員等が補機にアクセスするためのメンテナンス面２１２０Ｓとなる。 The +X side surface of the auxiliary unit 2120 in the fuel cell power generation system 2002 is, for example, the maintenance surface 2120S through which workers or the like can access the auxiliary equipment.
　枠体２１２０ｆにおいて、天面２１２０ｆＳの上側における周囲の一部はフレームレスになっている。メンテナンス部品が設けられる空間２１２０Ｖ、言い換えると、枠体２１２０ｆにおける天面２１２０ｆＳの上部の空間２１２０Ｖ、は、メンテナンス部品の周囲の少なくとも１面が開放された空間になっている。補機ユニット２１２０におけるメンテナンス部品が、枠体２１２０ｆにおける天面２１２０ｆＳに設けられることにより、メンテナンス面２１２０Ｓからアクセスを容易にできる。 In the frame 2120f, a portion of the periphery above the top surface 2120fS is frameless. The space 2120V in which the maintenance parts are provided, in other words the space 2120V above the top surface 2120fS of the frame 2120f, is a space with at least one side open around the maintenance parts. By providing the maintenance parts of the auxiliary unit 2120 on the top surface 2120fS of the frame 2120f, they can be easily accessed from the maintenance surface 2120S.
　また、メンテナンス部品の中で、メンテナンス作業が特に煩雑なメンテナンス部品、例えば、イオン交換器２１２５及びエアフィルタ２１２６は、メンテナンス面２１２０Ｓの近くに設けられる。メンテナンス部品の中で、メンテナンス作業が特に煩雑なメンテナンス部品が、メンテナンス面２１２０Ｓの近くに設けられることにより、メンテナンス作業における効率を高めることができる。 Furthermore, among the maintenance parts, those requiring particularly complicated maintenance work, such as the ion exchanger 2125 and the air filter 2126, are provided near the maintenance surface 2120S. By providing among the maintenance parts, those requiring particularly complicated maintenance work near the maintenance surface 2120S, the efficiency of the maintenance work can be improved.
　さらに、メンテナンス部品の一例であるリザーバータンク２１２４は、図３５から図３７に示す枠体２１２０ｆに両端持ちで固定されたサポート２１２０ｓ１により枠体２１２０ｆに固定される。また、メンテナンス部品の一例であるイオン交換器２１２５は、枠体２１２０ｆに両端持ちで固定されたサポート２１２０ｓ２と、断面係数を上げて剛性を高めたサポート２１２０ｔ１及びサポート２１２０ｔ２により枠体２１２０ｆに固定される。サポート２１２０ｔ１及びサポート２１２０ｔ２は、断面をＵ字形にすることにより、断面係数を上げて剛性を高める。 Furthermore, the reservoir tank 2124, which is an example of a maintenance part, is fixed to the frame body 2120f by support 2120s1 fixed to the frame body 2120f shown in Figures 35 to 37 at both ends. Furthermore, the ion exchanger 2125, which is an example of a maintenance part, is fixed to the frame body 2120f by support 2120s2 fixed to the frame body 2120f at both ends, and supports 2120t1 and 2120t2 whose section modulus has been increased to increase rigidity. Supports 2120t1 and 2120t2 have a U-shaped cross section, which increases the section modulus and increases rigidity.
　メンテナンス部品を両端持ちで固定されたサポート又は断面係数を上げて剛性を高めたサポートは、燃料電池発電装置２００２の運用時の振動や輸送時の衝撃に耐える剛性を備える。 Supports that have maintenance parts fixed at both ends or supports with increased rigidity due to an increased section modulus provide the rigidity to withstand vibrations during operation of the fuel cell power generation system 2002 and shocks during transportation.
　次に、補機ユニット２１２０における液系機器と電気系機器について説明する。図４０及び図４１のそれぞれは、第３Ａ実施形態に係る燃料電池発電装置の一例である燃料電池発電装置２００２における液系機器と電気系機器の配置について説明する図である。 Next, the liquid system devices and electrical system devices in the auxiliary unit 2120 will be described. Each of Figures 40 and 41 is a diagram explaining the arrangement of the liquid system devices and electrical system devices in a fuel cell power generation system 2002, which is an example of a fuel cell power generation system according to embodiment 3A.
　燃料電池発電装置２００２において、電気系機器は、液系機器から離隔して配置される。より具体的には、電気系機器が配置される空間は、液系機器が配置される空間と分けて設けられる。電気系機器は、空間ＳＥ１又は空間ＳＥ２に設けられる。電気系機器は、例えば、動力配線、信号配線、電気回路ボックス２１２７である。液系機器は、空間ＳＷに設けられる。液系機器は、例えば、冷却液配管、熱交換器２１２１、熱交換器２１２２、リザーバータンク２１２３、リザーバータンク２１２４及びイオン交換器２１２５である。 In the fuel cell power generation system 2002, the electrical system equipment is arranged away from the liquid system equipment. More specifically, the space in which the electrical system equipment is arranged is provided separately from the space in which the liquid system equipment is arranged. The electrical system equipment is provided in space SE1 or space SE2. The electrical system equipment is, for example, power wiring, signal wiring, and an electrical circuit box 2127. The liquid system equipment is provided in space SW. The liquid system equipment is, for example, a cooling liquid piping, a heat exchanger 2121, a heat exchanger 2122, a reservoir tank 2123, a reservoir tank 2124, and an ion exchanger 2125.
　燃料電池発電装置２００２において、電気系機器が液系機器から離隔して配置されることにより、液系機器から非常時に漏れた液が、電気配線等の電気系機器にかかることを抑制できる。液系機器から非常時に漏れた液が、電気配線等の電気系機器にかかることを抑制することにより、電気系機器において漏電を抑制できる。 In the fuel cell power generation system 2002, the electrical equipment is arranged away from the liquid equipment, which prevents liquid leaking from the liquid equipment in an emergency from coming into contact with electrical equipment such as electrical wiring. By preventing liquid leaking from the liquid equipment in an emergency from coming into contact with electrical equipment such as electrical wiring, leakage current in the electrical equipment can be prevented.
　さらに、燃料電池発電装置２００２において、燃料電池ユニットにおいて発電された電気を外部に流す動力配線は空間ＳＥ１に設けられる。また、燃料電池発電装置２００２において、燃料電池ユニットにおける信号を送受信するための信号配線は空間ＳＥ２に設けられる。空間ＳＥ２は、空間ＳＥ１に対して離隔して設けられる。空間ＳＥ１と空間ＳＥ２とが離隔して設けられることにより、信号配線は、動力配線から離隔して設けられる。なお、信号配線が動力配線から離隔して設けられる点については、第１実施形態に係る燃料電池発電装置の一例である燃料電池発電装置５０１の説明を参照することとして、ここでは詳細な説明は省略する。 Furthermore, in the fuel cell power generation apparatus 2002, power wiring for transmitting electricity generated in the fuel cell unit to the outside is provided in the space SE1. Furthermore, in the fuel cell power generation apparatus 2002, signal wiring for transmitting and receiving signals in the fuel cell unit is provided in the space SE2. The space SE2 is provided at a distance from the space SE1. By providing the spaces SE1 and SE2 at a distance, the signal wiring is provided at a distance from the power wiring. Note that with regard to the point that the signal wiring is provided at a distance from the power wiring, please refer to the explanation of the fuel cell power generation apparatus 501, which is an example of the fuel cell power generation apparatus according to the first embodiment, and a detailed explanation will be omitted here.

The frame member 2132 and the plate member 2132b form an opening 2132h2 on the -X side.
　上述のように、パレット２１３０は、Ｃ字形部材と平板の組合せを有する。 As described above, the pallet 2130 has a combination of C-shaped members and flat plates.
　枠部材２１３１と枠部材２１３２とを連結するために、パレット２１３０は、連結部材２１３３ａ、連結部材２１３３ｂ、連結部材２１３３ｃ、連結部材２１３３ｄ及び連結部材２１３３ｅを備える。連結部材２１３３ａ、連結部材２１３３ｂ、連結部材２１３３ｃ、連結部材２１３３ｄ及び連結部材２１３３ｅのそれぞれは、断面がＣ字形であるＣ字形部材又は断面がＵ字形であるＵ字形部材により構成される。 In order to connect frame member 2131 and frame member 2132, pallet 2130 includes connecting member 2133a, connecting member 2133b, connecting member 2133c, connecting member 2133d, and connecting member 2133e.
