However, in such a case, the temperature around the seal member could not be measured accurately, and the amount of fuel gas released had to be taken with a large margin in view of the margin value.
Moreover, in the said patent document 1, there were many auxiliary machines and it was difficult to use the seal member in an appropriate temperature range.
Further, the above-mentioned Patent Document 2 has a disadvantage that the structure is complicated.

そこで、この発明の目的は、燃料ガスタンクの開口部とバルブブロックとの間のシール部材の正確な温度を測定し、信頼性の高い燃料ガスタンクを構築することが可能な燃料電池システムを提供することにある。   Accordingly, an object of the present invention is to provide a fuel cell system capable of measuring a precise temperature of a seal member between an opening of a fuel gas tank and a valve block and constructing a highly reliable fuel gas tank. It is in.

この発明は、車両に搭載された燃料電池と、この燃料電池に燃料ガスを供給する燃料ガスタンクとを備えた車両用燃料電池システムにおいて、前記燃料ガスタンクの開口部にバルブブロックを設け、前記燃料ガスタンクの開口部と前記バルブブロックとの間にシール部材を設け、前記バルブブロックには前記シール部材近傍の温度を検出する第１温度検出手段を設けたことを特徴とする。   The present invention provides a vehicle fuel cell system comprising a fuel cell mounted on a vehicle and a fuel gas tank for supplying fuel gas to the fuel cell, wherein a valve block is provided at an opening of the fuel gas tank, and the fuel gas tank A seal member is provided between the opening and the valve block, and the valve block is provided with first temperature detecting means for detecting the temperature in the vicinity of the seal member.

この発明の燃料電池システムは、燃料ガスタンクの開口部とバルブブロックとの間にシール部材を設け、このシール部材の正確な温度を計測して信頼性の高い燃料ガスタンクを構築することが可能となる。   In the fuel cell system according to the present invention, a seal member is provided between the opening of the fuel gas tank and the valve block, and it is possible to construct a highly reliable fuel gas tank by measuring the accurate temperature of the seal member. .

この発明は、燃料ガスタンクの開口部とバルブブロックとの間のシール部材の正確な温度を計測し、信頼性の高い燃料ガスタンクを構築する目的を、シール部材の温度が使用下限温度未満となり、燃料ガスが燃料ガスタンクの開口部とバルブブロックとの隙間から漏れてしまうような状況に陥ることがないようにして実現するものである。
以下、図面に基づいてこの発明の実施例を詳細且つ具体的に説明する。 The purpose of this invention is to accurately measure the temperature of the seal member between the opening of the fuel gas tank and the valve block, and to construct a highly reliable fuel gas tank. This is realized in such a manner that the gas does not leak from the gap between the opening of the fuel gas tank and the valve block.
Hereinafter, embodiments of the present invention will be described in detail and specifically with reference to the drawings.

図１〜図４は、この発明の実施例を示すものである。
図３、図４において、１は燃料電池車の燃料電池システムである。この燃料電池システム１は、燃料電池車に搭載された燃料電池２と、この燃料電池２に燃料ガス（水素）を供給するタンクユニット３の円筒状の燃料ガスタンク（高圧水素タンク）４とを備える。この燃料電池２と燃料ガスタンク４とは、燃料供給管５で連結している。燃料ガスタンク４は、タンク本体６内に燃料ガス貯蔵空間７を形成している。 1 to 4 show an embodiment of the present invention.
3 and 4, reference numeral 1 denotes a fuel cell system of a fuel cell vehicle. The fuel cell system 1 includes a fuel cell 2 mounted on a fuel cell vehicle, and a cylindrical fuel gas tank (high-pressure hydrogen tank) 4 of a tank unit 3 that supplies fuel gas (hydrogen) to the fuel cell 2. . The fuel cell 2 and the fuel gas tank 4 are connected by a fuel supply pipe 5. The fuel gas tank 4 forms a fuel gas storage space 7 in the tank body 6.

タンク本体６には、ガスを充填、放出するための開口部９が形成されている。この開口部９は、口金構造を有し、内面に雌ねじ１８が形成されている。
燃料ガスタンク４の開口部９には、燃料ガス出力管５の端部を接続したバルブブロック１０が設けられる。
タンクユニット３にあっては、円筒状の二つの燃料ガスタンク４から構成され、この二つの燃料ガスタンク４の開口部９（バルブブロック１０側）を車両左側に向けて、横たわるように配置されている。具体的には、燃料ガスタンク４は、タンク固定フレームに載せられた状態で、タンク固定用バンドを用いてタンク固定フレームに固定されている。タンク固定フレームは、燃料ガスタンク４を搭載した状態で、車両フロアに下方より固定されている。これにより、燃料ガスタンク４は、燃料電池車に搭載されることになる。 The tank body 6 has an opening 9 for filling and discharging gas. The opening 9 has a base structure, and an internal thread 18 is formed on the inner surface.
The opening 9 of the fuel gas tank 4 is provided with a valve block 10 to which the end of the fuel gas output pipe 5 is connected.
The tank unit 3 is composed of two cylindrical fuel gas tanks 4 and is arranged to lie with the opening 9 (valve block 10 side) of the two fuel gas tanks 4 facing the left side of the vehicle. . Specifically, the fuel gas tank 4 is fixed to the tank fixing frame using a tank fixing band while being placed on the tank fixing frame. The tank fixing frame is fixed to the vehicle floor from below with the fuel gas tank 4 mounted thereon. As a result, the fuel gas tank 4 is mounted on the fuel cell vehicle.

バルブブロック１０は、図１に示すように、燃料ガスタンク４からの燃料ガスの充填放出を制御するものであり、燃料ガスタンク４の外部に位置するブロック本体１１と、開口部９から燃料ガスタンク４の内部に位置するブロック挿入部１２とを備えている。
このブロック挿入部１２は、タンク本体６の開口部９の厚さに対応する長さの大径部１３と、燃料ガス貯蔵空間７内に突出する小径部１４とからなる。
開口部９には、タンク本体６とブロック体１１との間のフランジ部１６と、開口部９の厚さに対応する長さの係合部１７とからなり、バルブブロック１０の大径部１３が固定されている。 As shown in FIG. 1, the valve block 10 controls the filling and discharging of the fuel gas from the fuel gas tank 4, and the block main body 11 located outside the fuel gas tank 4 and the opening 9 to the fuel gas tank 4. And a block insertion portion 12 located inside.
The block insertion portion 12 includes a large-diameter portion 13 having a length corresponding to the thickness of the opening 9 of the tank body 6 and a small-diameter portion 14 protruding into the fuel gas storage space 7.
The opening 9 includes a flange portion 16 between the tank body 6 and the block body 11, and an engagement portion 17 having a length corresponding to the thickness of the opening 9, and the large-diameter portion 13 of the valve block 10. Is fixed.

開口部９の内周面には、所定長さの雌ねじ１８が形成されるとともに、この雌ねじ１８の先端側にシール部材（Ｏリング）１９を設けるシール溝２０が形成されている。
バルブブロック１０の大径部１３の外周面には、開口部９の内周面に形成された雌ねじ１８に螺合する雄ねじ２１が形成される。
よって、バルブブロック１０は、燃料ガスタンク４の開口部９にねじ結合によって締結される。また、シール部材１９は、燃料ガスタンク４の開口部９とバルブブロック１０の大径部１３との間に配設され、燃料ガス貯蔵空間７の気密性を保持する。 A female screw 18 having a predetermined length is formed on the inner peripheral surface of the opening 9, and a seal groove 20 for forming a seal member (O-ring) 19 is formed on the distal end side of the female screw 18.
On the outer peripheral surface of the large-diameter portion 13 of the valve block 10, a male screw 21 that is screwed into the female screw 18 formed on the inner peripheral surface of the opening 9 is formed.
Therefore, the valve block 10 is fastened to the opening 9 of the fuel gas tank 4 by screw connection. The seal member 19 is disposed between the opening 9 of the fuel gas tank 4 and the large-diameter portion 13 of the valve block 10 to maintain the airtightness of the fuel gas storage space 7.

バルブブロック１０には、シール部材１９近傍の温度を検出するように、大径部１３で第１温度検出手段（温度センサ）２２が設けられる。この第１温度検出手段２２には、バルブブロック１０の内部を通って外部に延出する第１検出信号線２３が接続している。この第１検出信号線２３は、制御手段２４に連絡している。
そして、この制御手段２４においては、シール部材１９の実温度とシール部材１９近傍の温度とを事前に測定し、その温度関係をマップにして設定することで、シール部材１９近傍の温度の測定でシール部材１９自体の正確な温度を判断することが可能となり、よって、ボルトネックとなるシール部材１９の温度を把握することが可能となる。
また、バルブブロック１０には、燃料ガスタンク４から燃料電池２へと燃料ガスを供給する燃料ガス出力管５、シール部材１９の周囲温度を測定する第１温度検出手段２２の他、燃料ガス供給口から燃料フィルタを経由して充填される燃料ガスを燃料ガスタンク４ヘと供給する燃料ガス供給配管が接続される。 The valve block 10 is provided with first temperature detection means (temperature sensor) 22 at the large diameter portion 13 so as to detect the temperature in the vicinity of the seal member 19. A first detection signal line 23 extending to the outside through the inside of the valve block 10 is connected to the first temperature detecting means 22. The first detection signal line 23 communicates with the control means 24.
In this control means 24, the actual temperature of the seal member 19 and the temperature in the vicinity of the seal member 19 are measured in advance, and the temperature relationship is set as a map so that the temperature in the vicinity of the seal member 19 can be measured. It is possible to determine the exact temperature of the seal member 19 itself, and thus it is possible to grasp the temperature of the seal member 19 serving as a bolt neck.
The valve block 10 includes a fuel gas output port 5 for supplying fuel gas from the fuel gas tank 4 to the fuel cell 2, a first temperature detecting means 22 for measuring the ambient temperature of the seal member 19, and a fuel gas supply port. To the fuel gas tank 4 is connected to the fuel gas supply pipe for supplying the fuel gas filled via the fuel filter.

このような構造において、燃料ガスタンク４の開口部９にバルブブロック１０を設け、燃料ガスタンク４の開口部９とバルブブロック１０との間にシール部材１９を設け、バルブブロック１０にはシール部材１９近傍の温度を検出する第１温度検出手段２２を設けたことから、燃料ガスタンク４内に貯蔵された燃料ガスを、燃料電池２に供給するために放出する燃料ガス供給量（放出量）を決定する上で重要な要素であるシール部材１９の正確な温度を計測することが可能である。よって、シール部材１９の温度が使用下限温度未満となり燃料ガスが燃料ガスタンク４の開口部９とバルブブロック１０との隙間から漏れてしまうような状況に陥ることのない信頼性の高い燃料ガスタンク４を構築することが可能である。   In such a structure, a valve block 10 is provided in the opening 9 of the fuel gas tank 4, a seal member 19 is provided between the opening 9 of the fuel gas tank 4 and the valve block 10, and the valve block 10 has a vicinity of the seal member 19. Since the first temperature detecting means 22 for detecting the temperature of the fuel gas is provided, the fuel gas supply amount (discharge amount) to be released for supplying the fuel gas stored in the fuel gas tank 4 to the fuel cell 2 is determined. It is possible to measure the exact temperature of the seal member 19 which is an important factor. Therefore, the highly reliable fuel gas tank 4 that does not fall into a situation where the temperature of the seal member 19 is lower than the lower limit temperature and the fuel gas leaks from the gap between the opening 9 of the fuel gas tank 4 and the valve block 10 is provided. It is possible to build.

また、図１、図２に示すように、バルブブロック１０の先端には、ブロック挿入部１２で、第１温度検出手段２２に直接燃料ガスが当たらないように、壁部２５が径方向に延出して設けられる。
これにより、燃料ガスタンク４内に貯蔵された燃料ガスを燃料電池２へ放出する場合において、放出される燃料ガスが第１温度検出手段２２に直接当たるのを防ぐことができ、よって、シール部材１９の周囲の正確な温度を検出することが可能となる。 As shown in FIGS. 1 and 2, the wall portion 25 extends in the radial direction so that the fuel gas does not directly hit the first temperature detecting means 22 at the tip of the valve block 10 by the block insertion portion 12. Provided.
As a result, when the fuel gas stored in the fuel gas tank 4 is discharged to the fuel cell 2, it is possible to prevent the released fuel gas from directly hitting the first temperature detecting means 22, and thus the seal member 19. It becomes possible to detect the accurate temperature around the.

更に、図１、図２に示すように、第１温度検出手段２２は、燃料ガスタンク４の開口部９とバルブブロック１０とから構成される隔室２６に設けられている。この隔室２６は、前記壁部２５と開口部９の係合部１７の先端部１７Ａとの間に形成される。
これにより、燃料ガスタンク４内に貯蔵された燃料ガスを燃料電池２へ放出する状況（過程）においても、燃料ガスタンク４内を循環する放出される燃料ガス自体の温度に影響されることがない。よって、シール部材１９の周囲の正確な温度を検出することが可能である。 Further, as shown in FIGS. 1 and 2, the first temperature detecting means 22 is provided in a compartment 26 constituted by the opening 9 of the fuel gas tank 4 and the valve block 10. The compartment 26 is formed between the wall portion 25 and the distal end portion 17A of the engaging portion 17 of the opening 9.
Thus, even in a situation (process) in which the fuel gas stored in the fuel gas tank 4 is released to the fuel cell 2, the temperature of the released fuel gas circulating in the fuel gas tank 4 is not affected. Therefore, it is possible to detect the accurate temperature around the seal member 19.

また、図１に示すように、バルブブロック１０には、小径部１４の先端で、燃料ガスタンク４内の温度を検出する第２温度検出手段（温度センサ）２７が設けられる。この第２温度検出手段２７には、バルブブロック１０の内部を通って外部に延出する第２検出信号線２８が接続している。この第２検出信号線２８は、制御手段２４に連絡している。
これにより、制御手段２４において、第２温度検出手段２７による燃料ガスの温度と第１温度検出手段２２によるシール部材１９の温度とを同時に把握し、燃料ガスの放出量の調整等の制御をより細かく行い、燃料ガスを効率良く使用させることが可能となる。
また、二つの第１温度検出手段２２と第２温度検出手段２７とを、共に、バルブブロック１０に組み込むことができるので、第１温度検出手段２２・第２温度検出手段２７から延びる配線を束ねるクランプや、コネクタを共有化することが可能である。 As shown in FIG. 1, the valve block 10 is provided with second temperature detection means (temperature sensor) 27 that detects the temperature in the fuel gas tank 4 at the tip of the small diameter portion 14. A second detection signal line 28 extending to the outside through the inside of the valve block 10 is connected to the second temperature detecting means 27. The second detection signal line 28 communicates with the control means 24.
As a result, the control means 24 simultaneously grasps the temperature of the fuel gas by the second temperature detection means 27 and the temperature of the seal member 19 by the first temperature detection means 22, and performs more control such as adjustment of the discharge amount of the fuel gas. It is possible to use the fuel gas efficiently by performing finely.
Further, since the two first temperature detecting means 22 and the second temperature detecting means 27 can be incorporated into the valve block 10, the wires extending from the first temperature detecting means 22 and the second temperature detecting means 27 are bundled. It is possible to share clamps and connectors.

この実施例に係る燃料電池システム１おいては、上記の特許文献１と比較して、補機が少なく、シール部材１９を適正な温度域でのみ使用することが可能となる。
また、上記の特許文献２と比較して、燃料ガスタンク４内の温度ではなく、開口部９に取り付けられたシール部材１９の周囲の温度を測定することが目的であり、また、バルブブロック１０と第１温度検出手段２２・第２温度検出手段２７とが一体的なので、組付性が良く、さらに、調整する必要がなく、構造を簡単にすることが可能となる。 In the fuel cell system 1 according to this embodiment, compared with the above-described Patent Document 1, there are fewer auxiliary machines, and the seal member 19 can be used only in an appropriate temperature range.
Further, as compared with the above-mentioned Patent Document 2, the object is not to measure the temperature inside the fuel gas tank 4 but to measure the temperature around the seal member 19 attached to the opening 9, and the valve block 10 and Since the first temperature detecting means 22 and the second temperature detecting means 27 are integrated, the assemblability is good, and further, there is no need for adjustment, and the structure can be simplified.

なお、この発明においては、温度がボトルネックとなる部品の近傍に温度測定位置を設ける場合でも、同様の効果を得る。   In the present invention, the same effect can be obtained even when a temperature measurement position is provided in the vicinity of a component whose temperature becomes a bottleneck.

この発明に係る車両用燃料電池システムを、水素のみならず他の気体燃料の各種車両に適用することができる。   The vehicle fuel cell system according to the present invention can be applied not only to hydrogen but also to various types of vehicles using gaseous fuel.
