The hydrogen gas discharge passage is formed by mounting and the metal plate and the lower surface of the floor panel.
Thereby, the hydrogen staying in the recessed space is sucked out by the traveling airflow generation unit along the lower surface of the floor panel.

請求項３に記載の発明は、請求項１または２に記載の燃料電池自動車において、前記フロアパネルの一般面に対する前記燃料電池の下方突出量に応じ、前記水素ガス排出通路のガス排出口（例えば、後述の実施形態における開口２１ａ）を前記燃料電池の後方側に配置したことを特徴とする。

In the figure, the arrow FR indicates the front of the vehicle, the arrow LH indicates the left side of the vehicle, and the arrow UP indicates the upper side of the vehicle.

最初に、図１〜図４に示す第１の実施形態について説明する。
図１は、この発明にかかる燃料電池自動車１を側面から見た概略構成図である。この燃料電池自動車１は、水素と酸素の電気化学反応によって発電を行う燃料電池スタック２（以下、燃料電池２」と言う）を車体のフロア下に搭載するもので、該燃料電池２により生じた電力で電動モータ５を駆動して走行する。 First, the first embodiment shown in FIGS. 1 to 4 will be described.
FIG. 1 is a schematic configuration diagram of a fuel cell vehicle 1 according to the present invention as viewed from the side. The fuel cell vehicle 1 includes a fuel cell stack 2 (hereinafter referred to as a fuel cell 2) that generates power by an electrochemical reaction between hydrogen and oxygen, and is generated by the fuel cell 2. The electric motor 5 is driven with electric power to travel.

燃料電池２は、単位燃料電池（単位セル）を多数積層してなる周知の固体高分子膜型燃料電池（ＰＥＭＦＣ）であり、そのアノード側に燃料ガスとして水素ガスを供給し、カソード側に酸化剤ガスとして酸素を含む空気を供給することで、電気化学反応により水の生成とともに電力を発生する。   The fuel cell 2 is a well-known polymer electrolyte fuel cell (PEMFC) in which a large number of unit fuel cells (unit cells) are stacked. Hydrogen gas is supplied as a fuel gas to the anode side and oxidation is performed on the cathode side. By supplying air containing oxygen as the agent gas, electric power is generated along with the generation of water by an electrochemical reaction.

一方、この燃料電池自動車１は、車両左右のサイドフレーム３，３（図３参照）に、複数のビーム材から成るフレームユニットであるフロントサブフレーム４Ａとセンターサブフレーム４Ｂとリヤサブフレーム４Ｃが結合されている。
フロントサブフレーム４Ａには、車室の前方において、車両駆動源である電動モータ５が主に支持され、センターサブフレーム４Ｂには、車室下方の前部側において、燃料電池２と、その電池の補機類７ａ，７ｂとが支持されている。また、リヤサブフレーム４Ｃには、車室下方の後部側において、バッテリ８と、燃料電池２に水素を供給するための水素タンク９とが主に支持されている。なお、図１においては、１０は、燃料電池冷却用の冷却水を冷却するためのラジエータであり、１１Ｆ，１１Ｒは、車室内のフロントシートとリヤシートである。 On the other hand, in the fuel cell vehicle 1, a front subframe 4A, a center subframe 4B, and a rear subframe 4C, which are frame units made of a plurality of beam members, are coupled to the left and right side frames 3, 3 (see FIG. 3). Has been.
The front subframe 4A mainly supports an electric motor 5 as a vehicle drive source in front of the vehicle compartment, and the center subframe 4B has the fuel cell 2 and its battery on the front side below the vehicle compartment. The auxiliary machines 7a and 7b are supported. The rear subframe 4C mainly supports a battery 8 and a hydrogen tank 9 for supplying hydrogen to the fuel cell 2 on the rear side below the passenger compartment. In FIG. 1, 10 is a radiator for cooling the cooling water for cooling the fuel cell, and 11F and 11R are a front seat and a rear seat in the vehicle interior.

図３に示すように、車両の左右両側のサイドシル１２からサイドフレーム３とセンターサブフレーム４Ｂの上面にかけては、車室内に面するフロアパネル１３が取り付けられている。このフロアパネル１３の車幅方向の略中央部は車室内の上方に向かって略矩形状に膨出し、その膨出領域が車体前後方向に連続したセンターコンソール部１４となっている。このセンターコンソール部１４の下方側には凹空間１５が形成され、この凹空間１５の内側に、センターサブフレーム４Ｂに支持された燃料電池２と電池用補機類７ａ，７ｂが配置されている。   As shown in FIG. 3, a floor panel 13 facing the vehicle interior is attached from the side sills 12 on both the left and right sides of the vehicle to the upper surfaces of the side frames 3 and the center subframe 4B. A substantially central portion of the floor panel 13 in the vehicle width direction bulges in a substantially rectangular shape toward the upper side of the vehicle interior, and a bulge region forms a center console portion 14 that continues in the vehicle body front-rear direction. A concave space 15 is formed below the center console portion 14, and the fuel cell 2 and battery auxiliary devices 7a and 7b supported by the center subframe 4B are disposed inside the concave space 15. .

センターコンソール部１４は、図２に示すようにフロントシート１１Ｆに着座した乗員の足元付近から車体後方側に向かってほぼ一定高さに隆起し、フロントシート１１Ｆのシートバック１１Ｆｂ付近で一段高く隆起した後に、リヤシート１１Ｒの前方でフロアパネル１３の一般面と同一高さまで立ち下がっている。シートバック１１Ｆｂ付近で一段高く隆起した隆起部１４ａは、その上面側に乗員用の肘掛４２等が取り付けられるとともに、凹空間１５内の上方に一段高く拡張された領域１５ａ（以下、「拡張空間部１５ａ」と呼ぶ。）に、燃料電池２の各種の制御を行うための制御装置（ＥＣＵ）１６が収容されている。
また、フロアパネル１３の後縁部１３ａの下面には、リヤサブフレーム４Ｃに取り付けられるリヤフロアパネル１７が一体に接合されている。また、センターサブフレーム４Ｂの下面には、図３に示すように、少なくとも燃料電池２とセンターコンソール部１４の下方を覆うアンダーカバー１８が取り付けられている。 As shown in FIG. 2, the center console portion 14 protrudes from the vicinity of the feet of the passenger seated on the front seat 11F toward the rear side of the vehicle body at a substantially constant height, and rises one step higher near the seat back 11Fb of the front seat 11F. Later, it is lowered to the same height as the general surface of the floor panel 13 in front of the rear seat 11R. The raised portion 14a raised one step higher in the vicinity of the seat back 11Fb has an occupant's armrest 42 and the like attached to the upper surface side thereof, and an area 15a (hereinafter referred to as an "expanded space portion") that is extended higher up in the concave space 15. 15a ") accommodates a control device (ECU) 16 for performing various controls of the fuel cell 2.
A rear floor panel 17 attached to the rear sub-frame 4C is integrally joined to the lower surface of the rear edge portion 13a of the floor panel 13. Further, as shown in FIG. 3, an under cover 18 is attached to the lower surface of the center subframe 4 </ b> B so as to cover at least the lower part of the fuel cell 2 and the center console portion 14.

ところで、上記のように車体に取り付けられたフロアパネル１３の後縁部１３ａは、センターサブフレーム４Ｂのほぼ終端部となる位置にあり、車体の下面から見たときに若干の窪み形状となっている。このため、車両の走行時に車体下面に沿って流れる走行気流は、図２中の矢印で示すように、フロアパネル１３の下面側の後縁部１３ａ付近で湾曲した流れとなり、その湾曲した流れの周囲に負圧を作り出す。この負圧を作り出すフロアパネル１３の下面側の後縁部１３ａ付近の領域は、この発明における走行気流発生部１９となっている。   By the way, the rear edge portion 13a of the floor panel 13 attached to the vehicle body as described above is in a position that is substantially the end portion of the center sub-frame 4B, and is slightly recessed when viewed from the lower surface of the vehicle body. Yes. For this reason, the traveling airflow that flows along the lower surface of the vehicle body when the vehicle is traveling becomes a curved flow near the rear edge portion 13a on the lower surface side of the floor panel 13, as indicated by the arrow in FIG. Create negative pressure around. A region in the vicinity of the rear edge portion 13a on the lower surface side of the floor panel 13 that creates the negative pressure serves as a traveling airflow generation portion 19 in the present invention.

また、センターコンソール部１４の隆起部１４ａとフロアパネル１３の後縁部１３ａには、接続プラグ２０，２１が貫通して取り付けられ、車室内側に配管されたガス排出管２２の各端部が接続プラグ２０，２１に接続されている。接続プラグ２１の下端はフロアパネル１３の後縁部１３ａの下方に突出し、その下端の開口２１ａ（ガス排出口）が走行気流発生部１９内に臨んでいる。ガス排出管２２は、センターコンソール部１４の下方の拡張空間部１５ａと走行気流発生部１９を接続し、車両の走行時に走行気流発生部１９に生じる負圧を拡張空間部１５ａに作用させ、拡張空間部１５ａ内に滞留している水素ガスをベンチュリー効果によってフロアパネル１３の後縁部１３ａ下方に強制的に排出する。   Further, connecting plugs 20 and 21 are attached to the raised portion 14a of the center console portion 14 and the rear edge portion 13a of the floor panel 13, and each end portion of the gas exhaust pipe 22 piped to the vehicle interior side is provided. Connected to connection plugs 20 and 21. The lower end of the connection plug 21 protrudes below the rear edge portion 13 a of the floor panel 13, and the lower end opening 21 a (gas discharge port) faces the traveling airflow generation unit 19. The gas discharge pipe 22 connects the expansion space 15a below the center console section 14 and the traveling airflow generation section 19, and causes the negative pressure generated in the traveling airflow generation section 19 when the vehicle travels to act on the expansion space 15a. Hydrogen gas staying in the space 15a is forcibly discharged below the rear edge 13a of the floor panel 13 by the venturi effect.

なお、接続プラグ２１の開口２１ａの位置は、フロアパネル１３の一般面に対する燃料電池２の下方突出量に応じて決められている。すなわち、燃料電池２の車両後方側では燃料電池２の下方突出量に応じて走行気流の流速の速い領域が変化し、燃料電池２の下方突出量の増大に応じて走行気流の流速の速い領域が車両後方側に変化する。このため、接続プラグ２１の開口２１ａは、走行気流の流速のより速い位置に臨ませるために、燃料電池２の下方突出量の増大に応じて車両後方側になるように位置設定されている。   The position of the opening 21 a of the connection plug 21 is determined according to the downward protrusion amount of the fuel cell 2 with respect to the general surface of the floor panel 13. That is, on the vehicle rear side of the fuel cell 2, the region where the traveling airflow velocity is fast changes according to the downward protrusion amount of the fuel cell 2, and the region where the traveling airflow velocity is fast according to the increase of the downward protrusion amount of the fuel cell 2. Changes to the vehicle rear side. For this reason, the opening 21a of the connection plug 21 is positioned so as to be on the vehicle rear side in accordance with an increase in the downward projecting amount of the fuel cell 2 so as to face a position where the flow velocity of the traveling airflow is faster.

以上のように、この燃料電池自動車１においては、車両走行時に、フロアパネル１３の下面の走行気流発生部１９に生じる負圧がガス排出管２２を通してセンターコンソール部１４の凹空間１５内に作用して、凹空間１５内のガスを強制的に吸い出すようになるため、燃料電池２や補機類７ａ，７ｂ、接続配管等から漏れ出た水素を、電動ファン等を用いずに安定的に外部に排出することができる。
特に、この実施形態においては、センターコンソール部１４側の接続プラグ２０が、内壁高さが最も高く水素ガスの滞留し易い拡張空間部１５ａに臨んで設けられているため、センターコンソール部１４内に滞留する水素ガスを効率良く外部に排出することができる。 As described above, in the fuel cell vehicle 1, when the vehicle travels, the negative pressure generated in the traveling airflow generation unit 19 on the lower surface of the floor panel 13 acts in the recessed space 15 of the center console unit 14 through the gas discharge pipe 22. Because the gas in the concave space 15 is forcibly sucked out, the hydrogen leaked from the fuel cell 2, the auxiliary machines 7a and 7b, the connecting pipes, etc. can be stably discharged without using an electric fan or the like. Can be discharged.
In particular, in this embodiment, the connection plug 20 on the center console portion 14 side is provided facing the expansion space portion 15a having the highest inner wall height and in which hydrogen gas is likely to stay. The staying hydrogen gas can be efficiently discharged to the outside.

この燃料電池自動車１においては、接続プラグ２１の開口２１ａの位置が燃料電池２の下方突出量に応じて決められているため、走行気流のによる大きなベンチュリー効果を、水素ガスの強制排出に有効に用いることができる。   In this fuel cell vehicle 1, since the position of the opening 21a of the connection plug 21 is determined according to the downward projecting amount of the fuel cell 2, the large venturi effect due to the traveling airflow is effectively used for the forced discharge of hydrogen gas. Can be used.

図５は、この発明の第２の実施形態を示すものである。以下、この第２の実施形態も含め他の実施形態について説明するが、第１の実施形態と同一部分には同一符号を付し、重複する部分については説明を省略するものとする。
この実施形態の燃料電池自動車１０１は、基本的な構成は第１の実施形態とほぼ同様であるが、センターコンソール部１４内の凹空間１５と車両外部の走行気流発生部１９を接続するガス排出管１２２（水素ガス排出通路）がセンターコンソール部１４の車外側下面からフロアパネル１３の後縁部１３ａの下面にかけて配管されている点で第１の実施形態と異なっている。 FIG. 5 shows a second embodiment of the present invention. Hereinafter, other embodiments including the second embodiment will be described. However, the same parts as those of the first embodiment are denoted by the same reference numerals, and the description of the overlapping parts will be omitted.
The basic configuration of the fuel cell automobile 101 of this embodiment is substantially the same as that of the first embodiment, but the gas discharge that connects the recessed space 15 in the center console section 14 and the traveling airflow generation section 19 outside the vehicle. The pipe 122 (hydrogen gas discharge passage) is different from that of the first embodiment in that the pipe 122 (hydrogen gas discharge passage) is piped from the lower surface of the center console portion 14 to the lower surface of the rear edge portion 13a of the floor panel 13.

この燃料電池自動車１０１においては、第１の実施形態と同様に、走行気流を利用してセンターコンソール部１４内の凹空間１５から水素ガスを強制的に排出することができるが、ガス排出管１２２が車外側に配置されているため、車内側への水素ガスの進入をより確実に防止することができるとともに、車内側の有効スペースの拡大と見栄えの向上を図ることができる。   In this fuel cell vehicle 101, as in the first embodiment, hydrogen gas can be forcibly discharged from the recessed space 15 in the center console portion 14 using the traveling airflow, but the gas discharge pipe 122 is used. Is disposed outside the vehicle, it is possible to more reliably prevent hydrogen gas from entering the inside of the vehicle, and to increase the effective space inside the vehicle and improve the appearance.

図６〜図８は、この発明の第３の実施形態を示すものである。
この実施形態の燃料電池自動車２０１は、第１，第２の実施形態と基本的な構成は同様であり、また、水素ガス排出通路が車外側に配置されている点では第２の実施形態と同様であるが、水素ガス排出通路の具体的な構造が第２の実施形態と異なっている。
即ち、この実施形態の燃料電池自動車２０１では、図７に示すような断面ハット状の長尺な金属板３０がセンターコンソール部１４（フロアパネル１３）の隆起部１４ａの下面から後部壁１４ｂに沿って接合され、その金属板３０とフロアパネル１３の間で断面台形状の水素ガス排出通路が形成されている。この水素ガス排出通路３１は、センターコンソール部１４内の拡張空間１５ａとフロアパネル１３の後縁部１３ａの走行気流発生部１９を接続するように設けられている。 6 to 8 show a third embodiment of the present invention.
The fuel cell vehicle 201 of this embodiment has the same basic configuration as the first and second embodiments, and is different from the second embodiment in that the hydrogen gas discharge passage is arranged outside the vehicle. Although the same, the specific structure of the hydrogen gas discharge passage is different from that of the second embodiment.
That is, in the fuel cell automobile 201 of this embodiment, a long metal plate 30 having a cross-sectional hat shape as shown in FIG. 7 extends from the lower surface of the raised portion 14a of the center console portion 14 (floor panel 13) along the rear wall 14b. A hydrogen gas discharge passage having a trapezoidal cross section is formed between the metal plate 30 and the floor panel 13. The hydrogen gas discharge passage 31 is provided so as to connect the extended space 15a in the center console portion 14 and the traveling airflow generation portion 19 of the rear edge portion 13a of the floor panel 13.

この燃料電池自動車２０１は、第２の実施形態と同様の効果を得ることができることに加え、断面ハット状の金属板３０をフロアパネル１３の下面に取り付けて水素ガス排出通路を形成したことから、フロアパネル１３の下面側の水素ガス排出通路の占有スペースを小さくすることができる。   In addition to being able to obtain the same effects as in the second embodiment, this fuel cell automobile 201 has a hydrogen gas discharge passage formed by attaching a cross-sectional hat-shaped metal plate 30 to the lower surface of the floor panel 13. The space occupied by the hydrogen gas discharge passage on the lower surface side of the floor panel 13 can be reduced.

なお、この発明は上記の実施形態に限定されるものではなく、その要旨を逸脱しない範囲で種々の設計変更が可能である。   In addition, this invention is not limited to said embodiment, A various design change is possible in the range which does not deviate from the summary.
