車両に搭載される燃料電池システムにおいて、燃料電池は、例えば、固体高分子型燃料電池からなり、この固体高分子型燃料電池は、高分子イオン交換膜（「陽イオン交換膜」ともいう。）からなる電解質膜の両側に夫々アノード側電極及びカソード側電極を対設した電解質膜・電極構造体を、セパレータによって挟持することにより構成されている。   In a fuel cell system mounted on a vehicle, the fuel cell is composed of, for example, a polymer electrolyte fuel cell, and the polymer electrolyte fuel cell is also referred to as a polymer ion exchange membrane (also referred to as “cation exchange membrane”). An electrolyte membrane / electrode structure in which an anode side electrode and a cathode side electrode are opposed to each other on both sides of the electrolyte membrane is composed of a separator.

この種の燃料電池は、通常、電解質（「電解質膜」ともいう。）・電極構造体及びセパレータを所定数だけ積層することにより、燃料電池スタックとして使用されている。   This type of fuel cell is usually used as a fuel cell stack by stacking a predetermined number of electrolytes (also referred to as “electrolyte membranes”), electrode structures, and separators.

ところで、従来、燃料電池システムを搭載した車両においては、燃料電池スタック及び駆動用モータやインバータ、コンバータ等からなる車両駆動用補機から排出される熱量が、内燃機関よりも少ないものである。   Conventionally, in a vehicle equipped with a fuel cell system, the amount of heat discharged from a fuel cell stack and a vehicle driving auxiliary device including a driving motor, an inverter, a converter, and the like is smaller than that of an internal combustion engine.

この結果、燃料電池システムを搭載した車両において、内燃機関のものと同様な空調環境を得ようとすると、空調システムを大型化する必要があるとともに、消費電力も大きくなり、コストが大となって、経済的に不利であるという不都合がある。   As a result, in a vehicle equipped with a fuel cell system, to obtain an air conditioning environment similar to that of an internal combustion engine, it is necessary to increase the size of the air conditioning system, increase power consumption, and increase costs. There is a disadvantage that it is economically disadvantageous.

そこで、この発明は、上述不都合を除去するために、燃料電池スタックと、車両駆動用補機と、前記燃料スタックあるいは車両駆動用補機の少なくとも一方を冷却し、冷却水ポンプとラジエータとを設けた冷却系システムとを備えた車両用冷却装置において、前記冷却水ポンプを車室内に設置したことを特徴とする。   Therefore, in order to eliminate the above-described disadvantages, the present invention cools at least one of the fuel cell stack, the vehicle driving auxiliary device, the fuel stack or the vehicle driving auxiliary device, and includes a cooling water pump and a radiator. In the vehicular cooling device provided with the cooling system, the cooling water pump is installed in the vehicle interior.

In a vehicle cooling device equipped with a system system, a cooling water pump is installed in the vehicle interior. Therefore, in a vehicle equipped with a fuel cell system that emits less heat from the device that propels the vehicle by the cooling water pump, a heat source As the vehicle interior can be warmed and the heater capacity of the dedicated air conditioner can be reduced, the power consumption can be reduced and the air conditioning system can be downsized, and a vehicle equipped with an internal combustion engine Compared to the above, the amount of equipment and piping for propelling the vehicle is large. Can also be effective use of space in the old vehicle.

上述の如く発明したことにより、冷却水ポンプを車室内に設置し、冷却水ポンプを熱源として車室内を暖め、専用の空調装置のヒータ容量を小さくし、消費電力の低減と空調システムの小型化を実現するとともに、内燃機関を搭載する車両と比較して、車両を推進させるための装置及び配管の量の一部を車室内に設置し、ボディサイズの小さい車両においてもスペースを有効活用している。   By inventing as described above, the cooling water pump is installed in the vehicle interior, the vehicle interior is warmed using the cooling water pump as a heat source, the heater capacity of the dedicated air conditioner is reduced, power consumption is reduced, and the air conditioning system is downsized. Compared to a vehicle equipped with an internal combustion engine, a part of the device and the amount of piping for propelling the vehicle are installed in the passenger compartment, and the space is effectively used even in a vehicle with a small body size. Yes.

以下図面に基づいてこの発明の実施例を詳細に説明する。   Embodiments of the present invention will be described below in detail with reference to the drawings.

前記燃料電池スタック６は、通常、電解質（「電解質膜」ともいう。）・電極構造体及びセパレータを所定数だけ積層している。   The fuel cell stack 6 usually includes a predetermined number of electrolytes (also referred to as “electrolyte membranes”), electrode structures, and separators.

そして、前記車両２のフロントルーム１０内に、燃料電池スタック６及び駆動用モータやインバータ、コンバータ等からなる車両駆動用補機、例えばモータ１２とを配設し、燃料電池スタック６あるいはモータ１２の少なくとも一方、この実施例においては、燃料電池スタック６のみを冷却する前記冷却系システム８を設ける。   In the front room 10 of the vehicle 2, a fuel cell stack 6 and a vehicle driving auxiliary machine such as a motor 12 including a driving motor, an inverter, a converter, and the like are disposed. At least on the other hand, in this embodiment, the cooling system 8 for cooling only the fuel cell stack 6 is provided.

この冷却系システム８は、図２及び図３に示す如く、前記燃料電池スタック６と、この燃料電池スタック６に下流側端部が連絡する第１冷却水通路１４−１と、冷却水を循環させ、第１冷却水通路１４−１を介して燃料電池スタック６に冷却水を供給する冷却水ポンプ１６と、前記燃料電池スタック６の下流側端部に連絡する第２冷却水通路１４−２と、この第２冷却水通路１４−２を介して、前記燃料電池スタック６の下流側に連絡されるラジエータ１８と、このラジエータ１８を前記冷却水ポンプ１６に連絡させる第３冷却水通路１４−３と、第１〜第３冷却水通路１４−１、１４−２、１４−３に対して通路断面積が小で、且つ冷却水ポンプ１６を迂回するバイパス通路たる第４冷却水通路１４−４と、この第４冷却水通路１４−４の途中部位に配設されるリザーブタンク２０とを有している。   2 and 3, the cooling system 8 circulates the cooling water, the fuel cell stack 6, the first cooling water passage 14-1 whose downstream end communicates with the fuel cell stack 6, and the cooling water. A cooling water pump 16 for supplying cooling water to the fuel cell stack 6 via the first cooling water passage 14-1, and a second cooling water passage 14-2 communicating with the downstream end of the fuel cell stack 6. And a radiator 18 connected to the downstream side of the fuel cell stack 6 via the second cooling water passage 14-2, and a third cooling water passage 14- connecting the radiator 18 to the cooling water pump 16. 3 and the fourth cooling water passage 14-as a bypass passage having a small passage cross-sectional area with respect to the first to third cooling water passages 14-1, 14-2 and 14-3 and bypassing the cooling water pump 16. 4 and the fourth cooling water passage 14-4 And a reserve tank 20 disposed in the middle portion.

前記冷却系システム８の高さ位置関係について説明すると、図４に示す如く、前記冷却水ポンプ１６とラジエータ１８の下端とを同一高さ位置とし、ラジエータ１８よりも高い位置に前記燃料電池スタック６を位置させ、最上高さ位置には前記リザーブタンク２０を配置する。   The height positional relationship of the cooling system 8 will be described. As shown in FIG. 4, the cooling water pump 16 and the lower end of the radiator 18 are set at the same height position, and the fuel cell stack 6 is positioned higher than the radiator 18. The reserve tank 20 is disposed at the highest height position.

このリザーブタンク２０には、冷却水内に混入する空気を自動的に抜くことのできるデガス機構（図示せず）を設ける。このリザーブタンク２０部分において冷却水内に混入する空気を自動的に抜くことによって、特別な空気抜きライン設ける必要がないとともに、空気抜き作業も不要となり、この空気抜き作業を行うことなく冷却水の補充等のメンテナンスを行うことができるという利点がある。   The reserve tank 20 is provided with a degas mechanism (not shown) that can automatically remove air mixed in the cooling water. By automatically removing the air mixed in the cooling water in the reserve tank 20 part, it is not necessary to provide a special air venting line, and the air venting operation becomes unnecessary, so that the cooling water can be replenished without performing the air venting operation. There is an advantage that maintenance can be performed.

このとき、前記冷却水ポンプ１６を車室２２内に設置する構成とする。   At this time, the cooling water pump 16 is installed in the passenger compartment 22.

詳述すれば、図１及び図２に示す如く、前記車両２の車室２２内のフロア２４上に、運転席側、例えば車両右側に位置する第１フロントシート２６と、助手席側、例えば車両左側に位置する第２フロントシート２８とを設けた際に、前記冷却水ポンプ１６を助手席側の第２フロントシート２８下に位置させるものである。   More specifically, as shown in FIGS. 1 and 2, on the floor 24 in the passenger compartment 22 of the vehicle 2, the first front seat 26 located on the driver's seat side, for example, the right side of the vehicle, and the passenger seat side, for example, When the second front seat 28 located on the left side of the vehicle is provided, the cooling water pump 16 is positioned below the second front seat 28 on the passenger seat side.

ここで、前記冷却系システム８の平面的な位置関係について説明する。   Here, the planar positional relationship of the cooling system 8 will be described.

先ず、前記車両２のフロントルーム１０内において、図２に示す如く、車両２の左側に燃料電池スタック６を配設するとともに、車両２の右側にモータ１２を配設し、このモータ１２の車両前方に前記ラジエータ１８を配設し、前記燃料電池スタック６の左側には前記リザーブタンク２０を配設する。   First, in the front room 10 of the vehicle 2, as shown in FIG. 2, the fuel cell stack 6 is disposed on the left side of the vehicle 2, and the motor 12 is disposed on the right side of the vehicle 2. The radiator 18 is disposed in front, and the reserve tank 20 is disposed on the left side of the fuel cell stack 6.

また、前記車両２の車室２２内においては、図２に示す如く、前記冷却水ポンプ１６を車両２の左側に配設される助手席側の第２フロントシート２８下に設ける。   Further, in the passenger compartment 22 of the vehicle 2, the cooling water pump 16 is provided under the second front seat 28 on the passenger seat side provided on the left side of the vehicle 2, as shown in FIG. 2.

そして、前記冷却水ポンプ１６の出入口に連絡する第１冷却水通路１４−１及び第３冷却水通路１４−３は、前記車両２の車室２２内からフロア２４を貫通し、図示しない床下を車両前方に指向するように配設する。   And the 1st cooling water channel 14-1 and the 3rd cooling water channel 14-3 which connect with the entrance and exit of the above-mentioned cooling water pump 16 penetrate the floor 24 from the inside of the interior 22 of the above-mentioned vehicle 2, and under the floor which is not illustrated. It arrange | positions so that it may face in front of a vehicle.

前記第１〜第４冷却水通路１４−１、１４−２、１４−３、１４−４内を流れる冷却水温度は、６０〜８０度である。   The temperature of the cooling water flowing through the first to fourth cooling water passages 14-1, 14-2, 14-3, 14-4 is 60 to 80 degrees.

なお、符号３０は、前記車両２の後方に搭載される、前記燃料電池システム４の燃料用タンクである。   Reference numeral 30 denotes a fuel tank of the fuel cell system 4 mounted on the rear side of the vehicle 2.

次に作用を説明する。   Next, the operation will be described.

前記冷却水ポンプ１６が駆動されると、図２に示す如く、冷却水ポンプ１６は、第３冷却水通路１４−３を介して、上流のラジエータ１８側から熱交換後の冷却水を取り込むとともに、第１冷却水通路１４−１を介して、下流の前記燃料電池スタック６側に冷却水を供給する。   When the cooling water pump 16 is driven, the cooling water pump 16 takes in the cooling water after heat exchange from the upstream radiator 18 side via the third cooling water passage 14-3, as shown in FIG. Then, cooling water is supplied to the downstream fuel cell stack 6 side via the first cooling water passage 14-1.

この燃料電池スタック６を通過した冷却水は、第２冷却水通路１４−２を介して、前記ラジエータ１８に戻される。   The coolant that has passed through the fuel cell stack 6 is returned to the radiator 18 through the second coolant passage 14-2.

そしてこのとき、前記リザーブタンク２０は、図２に示す如く、第４冷却水通路１４−４によって、第１〜第３冷却水通路１４−１、１４−２、１４−３中を流れる冷却水量を一定に保つとともに、冷却水内に混入する空気を、デガス機構（図示せず）により自動的に抜いている。   At this time, as shown in FIG. 2, the reserve tank 20 has an amount of cooling water flowing through the first to third cooling water passages 14-1, 14-2, 14-3 by the fourth cooling water passage 14-4. The air mixed in the cooling water is automatically extracted by a degas mechanism (not shown).

これにより、前記車両２の車室２２内に設置した前記冷却水ポンプ１６によって、車両２を推進する装置から排出される熱量が少ない燃料電池システムを搭載した車両２において、熱源として車室２２内を暖めることが可能であり、専用の空調装置のヒータ容量を小さくすることができるため、消費電力の低減と空調システムの小型化を実現することができる。   As a result, in the vehicle 2 equipped with the fuel cell system in which the amount of heat discharged from the device for propelling the vehicle 2 is reduced by the cooling water pump 16 installed in the vehicle compartment 22 of the vehicle 2, Since the heater capacity of the dedicated air conditioner can be reduced, power consumption can be reduced and the air conditioning system can be downsized.

また、内燃機関を搭載する車両と比較して、車両を推進させるための装置及び配管の量が多いので、一部を車室２２内に設置できることにより、ボディサイズの小さい車両においてもスペースを有効活用することができるものである。   In addition, compared to a vehicle equipped with an internal combustion engine, the amount of equipment and piping for propelling the vehicle is large, so that a part of the device can be installed in the passenger compartment 22 so that space can be saved even in a vehicle with a small body size. It can be used.

更に、前記冷却水ポンプ１６を助手席側の第２フロントシート２８下に設けたことにより、乗員の下半身を主に暖房することができ、効率のよい空調装置を実現することができる。   Further, by providing the cooling water pump 16 below the second front seat 28 on the passenger seat side, the lower body of the passenger can be mainly heated, and an efficient air conditioner can be realized.

なお、この発明は上述実施例に限定されるものではなく、種々の応用改変が可能である。   The present invention is not limited to the above-described embodiments, and various application modifications are possible.

例えば、この発明の実施例においては、冷却水ポンプを車室内に設ける際に、車両左側に位置する助手席側の第２フロントシート下に前記冷却水ポンプを設ける構成としたが、診療右側に位置する運転席側の第１フロントシート下や足下部位、あるいはリヤシート下等に冷却水ポンプを設ける特別構成とすることも可能である。   For example, in the embodiment of the present invention, when the cooling water pump is provided in the passenger compartment, the cooling water pump is provided below the second front seat on the passenger seat side on the left side of the vehicle. It is also possible to adopt a special configuration in which a cooling water pump is provided under the first front seat or the foot portion on the driver seat side or under the rear seat.

さすれば、車室内の余剰部位を利用して冷却水ポンプを配設でき、ボディサイズの小さい車両におけるスペースの有効利用を図ることができるとともに、冷却水ポンプが熱源として機能することとなり、消費電力の低減と空調システムの小型化とに寄与し得るものである。   Then, the cooling water pump can be arranged by using the surplus part in the passenger compartment, and the space in the vehicle having a small body size can be effectively used, and the cooling water pump functions as a heat source, so that This can contribute to reduction of electric power and downsizing of the air conditioning system.

また、この発明の実施例においては、前記冷却水ポンプを熱源とするために、車室内、特に助手席側の第２フロントシート下に冷却水ポンプを設ける構成としたが、冷却水ポンプ以外にも、熱源となりうる部品をフロントシート下や足下部位等に配置する特別構成とすることも可能である。   In the embodiment of the present invention, in order to use the cooling water pump as a heat source, the cooling water pump is provided in the passenger compartment, particularly under the second front seat on the passenger seat side. However, it is also possible to adopt a special configuration in which components that can serve as heat sources are arranged under the front seat or under the foot.

すなわち、冷却水ポンプ以外にも、熱源となりうる部品を車室内に配置することによって、熱源によって車室内を暖めることが可能となり、空調装置のヒータ能力を低く設定することができ、ヒータ消費電力の抑制に寄与し得るものである。   In other words, in addition to the cooling water pump, by disposing components that can serve as heat sources in the vehicle interior, the vehicle interior can be warmed by the heat source, the heater capacity of the air conditioner can be set low, and the heater power consumption can be reduced. It can contribute to suppression.
