Description

本発明は、盗難防止機能を備えた燃料電池船に関する。 The present invention relates to a fuel cell ship having an anti-theft function.

電動船外機の電源として燃料電池を用いることが検討されている。例えば、特許文献１には、船体内部に燃料タンク及びバッテリを配置し、船体外部に燃料電池、電動モータ、プロペラを配置した燃料電池船が開示されている。 The use of fuel cells as a power source for electric outboard motors is being considered.

しかし、船外機に搭載されることが一般的な電動モータに比較して、燃料電池（発電装置）は大型であるうえ、水素燃料を供給するための配管で船体内部の燃料タンクと連結される必要があり、このレイアウトは現実的とは言えない。また、小型船舶にあっては盗難の問題も憂慮されるが、特許文献１には盗難対策に関する記載はない。 However, compared to electric motors that are generally mounted on outboard motors, fuel cells (power generators) are larger and are connected to the fuel tank inside the hull by pipes for supplying hydrogen fuel. This layout is not realistic. In addition, although the problem of theft is a concern for small vessels, Patent Document 1 does not describe measures against theft.

本発明は従来技術の上記の点に鑑みてなされたものであり、その目的は、盗難防止機能を備えた燃料電池船を提供することにある。 The present invention has been made in view of the above points of the prior art, and an object of the present invention is to provide a fuel cell ship having an anti-theft function.

A means (12a) for detecting the opening is provided, and when the illegal opening is detected, the relief valve is opened and hydrogen is discharged from the hydrogen fuel tank.

本発明に係る燃料電池船は、上記構成により、二次電池を収容する収納部の蓋部材が不正開放された場合に、水素燃料タンクから水素が積極的に排出されることで、素早く燃料を枯渇させ、盗難を防ぐうえで有利である。 According to the above configuration, the fuel cell ship according to the present invention quickly discharges fuel by actively discharging hydrogen from the hydrogen fuel tank when the lid member of the storage portion accommodating the secondary battery is illegally opened. It is advantageous in depleting and preventing theft.

A fuel cell stack, a fuel side header, an air side header, a compressor (not shown), a controller 21, and the like are provided, and a cooling fan 20 is attached.

水素燃料タンク３は、水素を気体のまま貯蔵する高圧水素タンクや低圧水素タンクを用いることもできるが、容器の内部に水素を分子状態で吸蔵／放出可能な水素吸蔵合金を収容した水素吸蔵合金タンクが好適である。吸蔵合金の金属種は、特に限定されるものではないが、可及的低温かつ低圧で水素放出可能な金属種が好ましい。 As the hydrogen fuel tank 3, a high-pressure hydrogen tank or a low-pressure hydrogen tank that stores hydrogen as a gas can be used, but a hydrogen storage alloy containing a hydrogen storage alloy capable of storing / releasing hydrogen in a molecular state inside the container. A tank is suitable. The metal type of the storage alloy is not particularly limited, but a metal type capable of releasing hydrogen at a low temperature and a low pressure as much as possible is preferable.

水素燃料タンク３の一端には燃料電池ユニット２に水素燃料を供給するための供給管３３が接続され、他端には非常時に水素を排出するためのリリーフ弁３０が設けられているが、これらの配置はこれ以外であってもよい。 A supply pipe 33 for supplying hydrogen fuel to the fuel cell unit 2 is connected to one end of the hydrogen fuel tank 3, and a relief valve 30 for discharging hydrogen in an emergency is provided at the other end. The arrangement of may be other than this.

As the heater 31, a resistance heating element or an electric heater that generates heat when energized is preferably used.

二次電池４は、燃料電池ユニット２で発電される電気を充電しておき、二次電池４から電動船外機６のモータに給電することで、起動時に発電能力が低下する燃料電池ユニット２の特性を補い、電動船外機６の安定的な駆動を可能にするために搭載されており、リチウムイオンバッテリ（ＬＩＢ）などが好適である。 The secondary battery 4 charges the electricity generated by the fuel cell unit 2 and supplies power from the secondary battery 4 to the motor of the electric outboard unit 6, so that the power generation capacity is reduced at the time of starting the fuel cell unit 2. It is installed to supplement the characteristics of the above and enable stable driving of the electric outboard unit 6, and a lithium ion battery (LIB) or the like is suitable.

コンバータ５は、燃料電池ユニット２や二次電池４の電圧を調整するためのＨＶＤＣ／ＤＣコンバータである。本実施形態では、燃料電池ユニット２の出力電圧（約１００Ｖ）を二次電池４の電圧（４８Ｖ）まで降圧し、上述のように二次電池４から電動船外機６に電力を安定供給する降圧タイプが使用されるが、高出力が求められる場合には、燃料電池ユニット２や二次電池４の電圧を高電圧に変換して電動船外機６に供給する昇圧タイプを使用することもできる。 The converter 5 is an HVDC / DC converter for adjusting the voltage of the fuel cell unit 2 and the secondary battery 4. In the present embodiment, the output voltage (about 100V) of the fuel cell unit 2 is stepped down to the voltage (48V) of the secondary battery 4, and power is stably supplied from the secondary battery 4 to the electric outboard unit 6 as described above. A step-down type is used, but if high output is required, a step-up type that converts the voltage of the fuel cell unit 2 or secondary battery 4 into a high voltage and supplies it to the electric outboard unit 6 can also be used. it can.

降圧コンバータ７は、燃料電池ユニット２や二次電池４の電力の一部を低電圧に変換するための１２ＶＤＣ／ＤＣコンバータであり、変換された電力は低圧用二次電池８（１２Ｖバッテリ）に蓄電され、燃料電池ユニット２に付設されたコンプレッサー（ブロワ）や電磁バルブ、冷却用ファン２０、コントローラ２１、などの補機類、および、電力管理装置９や制御装置１４に供給される。 The step-down converter 7 is a 12 VDC / DC converter for converting a part of the electric power of the fuel cell unit 2 and the secondary battery 4 into a low voltage, and the converted electric power is converted into the low voltage secondary battery 8 (12 V battery). The electricity is stored and supplied to auxiliary equipment such as a compressor (blower) and an electromagnetic valve attached to the fuel cell unit 2, a cooling fan 20, a controller 21, and a power management device 9 and a control device 14.

収納部１０は、図示例では、船体後部に並設された２つの収納部１１，１２からなり、船体右側の第１収納部１１に燃料電池ユニット２と水素燃料タンク３が収容され、船体左側の第２収納部１２に二次電池４、コンバータ５、降圧コンバータ７、二次電池８、電力管理装置９、および、制御装置１４が収容されている。なお、収納部１１，１２は、船体に備わる既存の収納部（デッキストレージ）を利用しても良いし、何れか一方または両方が既存の収納部とは別に設けられたケース等であっても良い。 In the illustrated example, the storage unit 10 is composed of two storage units 11 and 12 arranged side by side in the rear part of the hull, and the fuel cell unit 2 and the hydrogen fuel tank 3 are housed in the first storage unit 11 on the right side of the hull, and the left side of the hull. A secondary battery 4, a converter 5, a step-down converter 7, a secondary battery 8, a power management device 9, and a control device 14 are housed in the second storage unit 12. The storage units 11 and 12 may use the existing storage unit (deck storage) provided on the hull, or even if one or both of them are provided separately from the existing storage unit. good.

燃料電池ユニット２の出力側は、中央の連通部１３に挿通された配線２５により電力管理装置９を介してコンバータ５の入力側に接続されており、二次電池４の入出力は配線２４により電力管理装置９を介して燃料電池ユニット２の出力側（充電時）またはコンバータ５の入力側（放電時）に選択的に接続されるようになっている。 The output side of the fuel cell unit 2 is connected to the input side of the converter 5 via the power management device 9 by the wiring 25 inserted through the central communication portion 13, and the input / output of the secondary battery 4 is connected by the wiring 24. It is selectively connected to the output side (during charging) of the fuel cell unit 2 or the input side (during discharging) of the converter 5 via the power management device 9.

また、水素燃料タンク３のヒータ３１は、中央の連通部１３に挿通された配線４３により二次電池４に接続され、二次電池４から電力が供給されるようになっている。なお、連通部１３は配線２５，４３等が配策された後にシール材等で封止されることが好ましい。 Further, the heater 31 of the hydrogen fuel tank 3 is connected to the secondary battery 4 by a wiring 43 inserted into the central communication portion 13, and power is supplied from the secondary battery 4. It is preferable that the communication portion 13 is sealed with a sealing material or the like after the wirings 25, 43 and the like are arranged.

各収納部１１，１２は、船体甲板上の開口部１１ｃ，１２ｃを密閉するための蓋部材１１ｂ，１２ｂ（ハッチ）を備えるとともに、蓋部材１１ｂまたは１２ｂの不正開放を検知するセンサ１１ａ，１２ａが対応する収納部１１，１２内に設けられている。 Each of the storage portions 11 and 12 is provided with lid members 11b and 12b (hatch) for sealing the openings 11c and 12c on the hull deck, and sensors 11a and 12a for detecting unauthorized opening of the lid members 11b or 12b are provided. It is provided in the corresponding storage units 11 and 12.

センサ１１ａ，１２ａは、例えば、燃料電池船１の停泊中に、蓋部材１１ｂ，１２ｂが不正開放された場合における収納部１１，１２の圧力変化を検知する圧力センサで構成されるが、蓋部材１１ｂ，１２ｂに生じる開度を検知するスイッチや、蓋部材１１ｂ，１２ｂの不正開放に伴う振動を検知するセンサとすることができる。また、第１収納部１１内のセンサ１１ａは、第１収納部１１内の酸素濃度を検知するセンサを利用することもできる。この場合、通常は運転直後の低酸素濃度状態から徐々に大気圧と同等まで上昇するので、急激に酸素濃度が変化した場合には不正開放されたものと推定できる。 The sensors 11a and 12a are composed of, for example, pressure sensors that detect pressure changes in the storage portions 11 and 12 when the lid members 11b and 12b are illegally opened while the fuel cell ship 1 is berthed. It can be a switch for detecting the opening degree of the lid members 11b and 12b and a sensor for detecting the vibration caused by the illegal opening of the lid members 11b and 12b. Further, as the sensor 11a in the first storage unit 11, a sensor that detects the oxygen concentration in the first storage unit 11 can also be used. In this case, normally, the oxygen concentration gradually rises from the low oxygen concentration state immediately after the operation to the same level as the atmospheric pressure, so it can be estimated that the oxygen concentration is illegally released when the oxygen concentration changes suddenly.

上記各場合において、センサやスイッチで蓋部材１１ｂ，１２ｂの開状態が検知されることで、制御装置１４がオンになるように構成することが好ましい。また、何れの場合も、一度オンになるとセンサやスイッチの復帰動作では制御装置１４がオフにならないように構成することが好ましい。また、蓋部材１１ｂ，１２ｂに施錠機構を設け、施錠操作によって上記センサやスイッチがアクティブになるように構成することもできる。このような構成とすることで、施錠機構の鍵が不正入手された場合の盗難を防止できる。 In each of the above cases, it is preferable that the control device 14 is turned on when the open state of the lid members 11b and 12b is detected by the sensor or the switch. Further, in any case, it is preferable to configure the control device 14 so that the control device 14 does not turn off in the return operation of the sensor or the switch once it is turned on. Further, the lid members 11b and 12b may be provided with a locking mechanism so that the sensor or switch is activated by the locking operation. With such a configuration, it is possible to prevent theft when the key of the locking mechanism is illegally obtained.

なお、第１収納部１１には、燃料電池ユニット２の冷却用および反応用の空気を導入するための吸気部と、冷却後の空気や燃料電池ユニット２から排出される水蒸気を排出するための排気部を兼ねた吸排気部１５が設けられている。この吸排気部１５は塩害対策のための耐塩フィルタを備え、非使用時に密閉するためのサブハッチ３４を備えている。なお、吸気部と排気部は個別に設けられてもよい。 The first storage unit 11 has an intake unit for introducing air for cooling and reaction of the fuel cell unit 2, and an intake unit for discharging air after cooling and water vapor discharged from the fuel cell unit 2. An intake / exhaust unit 15 that also serves as an exhaust unit is provided. The intake / exhaust unit 15 is provided with a salt-resistant filter for measures against salt damage, and is provided with a sub-hatch 34 for sealing when not in use. The intake unit and the exhaust unit may be provided separately.

以上のように構成された燃料電池船１は、非使用時には制御装置１４およびセンサ１１ａ，１２ａが動作可能な状態となり、盗難防止機能が有効になる。 In the fuel cell ship 1 configured as described above, the control device 14 and the sensors 11a and 12a are in an operable state when not in use, and the anti-theft function becomes effective.

この状態において、蓋部材１１ｂ，１２ｂ（または吸排気部１５のサブハッチ３４）が開放された場合、すなわち、不正開放された場合には、センサ１１ａまたは１２ａからの検知信号が制御装置１４に送られ、制御装置１４は、電力管理装置９に内蔵されているブレーカによって配線２５を遮断し、燃料電池ユニット２および二次電池４からコンバータ５（電動船外機６）側に給電できないようにする。 In this state, when the lid members 11b and 12b (or the sub-hatch 34 of the intake / exhaust unit 15) are opened, that is, when they are illegally opened, a detection signal from the sensor 11a or 12a is sent to the control device 14. The control device 14 cuts off the wiring 25 by a breaker built in the power management device 9 so that the fuel cell unit 2 and the secondary battery 4 cannot supply power to the converter 5 (electric outboard unit 6) side.

しかし、配線２５が遮断されるのみでは、直結配線等により、燃料電池ユニット２または二次電池４の何れかから電動船外機６に給電される虞があるので、制御装置１４は、さらに以下の（ｉ）〜（ｉｉｉ）の盗難防止措置を発動する。 However, if the wiring 25 is only cut off, power may be supplied to the electric outboard motor 6 from either the fuel cell unit 2 or the secondary battery 4 due to the direct wiring or the like. Therefore, the control device 14 is further described below. Invoke the anti-theft measures of (i) to (iii).

（ｉ）水素燃料タンク３のリリーフ弁３０を開放するとともに、二次電池４から配線４３を通じてヒータ３１に給電する。水素燃料タンク３が加熱されることで水素吸蔵合金から水素の放出が促進され、リリーフ弁３０を通じて水素が排出される。 (I) The relief valve 30 of the hydrogen fuel tank 3 is opened, and power is supplied from the secondary battery 4 to the heater 31 through the wiring 43. By heating the hydrogen fuel tank 3, the release of hydrogen from the hydrogen storage alloy is promoted, and hydrogen is discharged through the relief valve 30.

（ｉｉ）燃料電池ユニット２を起動し、水素燃料タンク３内に残留する水素燃料が燃料電池ユニット２によっても消費されるようにする。この時、燃料電池ユニット２で発電される電力は電力管理装置９および配線２４を介して二次電池４に充電に充当されるが、二次電池４からヒータ３１に給電することで、二次電池４の電力も消費される。 (Ii) The fuel cell unit 2 is started so that the hydrogen fuel remaining in the hydrogen fuel tank 3 is also consumed by the fuel cell unit 2. At this time, the electric power generated by the fuel cell unit 2 is applied to the secondary battery 4 via the power management device 9 and the wiring 24, but the secondary battery 4 supplies power to the heater 31 to supply the secondary battery 4. The power of the battery 4 is also consumed.

（ｉｉｉ）二次電池４からの給電によって冷却用ファン２０が起動し、水素燃料タンク３からリリーフ弁３０を通じて排出される水素燃料が外気に拡散されるようにするとともに、冷却用ファン２０の作動により二次電池４の電力消費が促進されるようにする。 (Iii) The cooling fan 20 is started by the power supply from the secondary battery 4, so that the hydrogen fuel discharged from the hydrogen fuel tank 3 through the relief valve 30 is diffused to the outside air, and the cooling fan 20 is operated. The power consumption of the secondary battery 4 is promoted.

以上のような盗難防止措置が発動されることで、直結配線等により、燃料電池ユニット２または二次電池４の何れかから電動船外機６側への給電が可能になったとしても、直結配線等の作業で時間が経過する間に、水素燃料タンク３の水素燃料および二次電池４の電力が枯渇し、燃料電池船１は走行不能な状態になっているので、盗難を阻止できる。 By invoking the anti-theft measures as described above, even if it becomes possible to supply power from either the fuel cell unit 2 or the secondary battery 4 to the electric outboard unit 6 side by direct wiring or the like, it is directly connected. Since the hydrogen fuel in the hydrogen fuel tank 3 and the electric power of the secondary battery 4 are exhausted while the time elapses in the work such as wiring, the fuel cell ship 1 is in a non-running state, so that theft can be prevented.

なお、上記（ｉ）〜（ｉｉｉ）の盗難防止措置のうち、上記（ｉ）のみ発動するとともに、遮断弁３２で燃料電池ユニット２への水素燃料の供給を遮断するように構成することもできる。さらに、この構成において、遮断弁３２の作動後に、不正アクセスの履歴解除または直結配管等の手段で燃料電池ユニット２が起動された場合に、上記（ｉｉ）〜（ｉｉｉ）の盗難防止措置が発動するように構成することもできる。また、上記（ｉｉｉ）に加えて、二次電池４からの給電によって燃料電池船１のライトを点灯させ、二次電池４の電力消費が促進されるように構成することもできる。 Of the anti-theft measures (i) to (iii), only the above (i) can be activated, and the shutoff valve 32 can be configured to shut off the supply of hydrogen fuel to the fuel cell unit 2. .. Further, in this configuration, when the fuel cell unit 2 is activated by means such as canceling the history of unauthorized access or direct connection piping after the shutoff valve 32 is activated, the anti-theft measures (ii) to (iii) described above are activated. It can also be configured to do so. Further, in addition to the above (iii), it is also possible to turn on the light of the fuel cell ship 1 by supplying power from the secondary battery 4 so that the power consumption of the secondary battery 4 is promoted.

上記実施形態では、蓋部材１１ｂ，１２ｂとしてヒンジやスライダにより開閉可能なハッチが使用される場合を想定しているが、ネジなどの締結手段やクランプなどの緊締手段により着脱開閉可能な蓋部材など、各種の蓋部材を使用でき、さらに、剛性部材以外の蓋部材、例えば、可撓性のシート材料からなる蓋部材の使用や併用を妨げるものではなく、その場合、蓋部材の周縁部と開口部の縁部との間をファスナーで開閉可能とすることができる。 In the above embodiment, it is assumed that a hatch that can be opened and closed by a hinge or a slider is used as the lid members 11b and 12b, but a lid member that can be attached and detached by a fastening means such as a screw or a tightening means such as a clamp or the like. , Various lid members can be used, and further, it does not prevent the use or combined use of a lid member other than the rigid member, for example, a lid member made of a flexible sheet material, in which case the peripheral edge and the opening of the lid member. It can be opened and closed with a fastener between the portion and the edge of the portion.

以上、本発明のいくつかの実施形態について述べたが、本発明はこれに限定されるものではなく、本発明の技術的思想に基づいてさらに各種の変形および変更が可能である。 Although some embodiments of the present invention have been described above, the present invention is not limited to this, and various modifications and modifications can be made based on the technical idea of the present invention.
