A discharge side manifold 36 that is a pipe to be connected is attached. The substantially cylindrical hydrogen cylinder 15 is supported by the rear frame 9 and the guide pipe 10 above the rear wheels (drive wheels) WR with the valve side connected to the hydrogen cylinder regulator 16 facing the front of the vehicle body. The hydrogen charged in the hydrogen cylinder 15 is reduced in pressure by a hydrogen cylinder regulator 16 that is electrically controlled based on information from various sensors and the like, and then supplied to the fuel cell 30 via the fuel gas pipe 45. A rear cowl 14 as a part of the exterior part is disposed above the rear frame 9 so as to cover the hydrogen cylinder 15.

前記ハンドルポスト４の車体前方側には、外気を濾過するエアクリーナボックス５４が設けられており、該エアクリーナボックス５４から導入された空気は、スクロール型圧縮機５２によって加湿機５３に圧送される。そして、加湿機５３によって適切な湿度が与えられた反応ガスは、反応ガス管３４およびこれに接続される吸入側マニホールド３３を介して、燃料電池３０に圧送される。   An air cleaner box 54 that filters outside air is provided on the front side of the vehicle body of the handle post 4, and air introduced from the air cleaner box 54 is pumped to the humidifier 53 by the scroll compressor 52.

図３は、燃料電池車両１の上面図である。図４は、燃料電池車両１の左側面図であり、また、図５は燃料電池車両１の外装部品の一例を示す斜視図である。前記と同一符号は、同一または同等部分を示す。車幅方向中央に配設される燃料電池３０の上部には、燃料ガス管４５が接続される燃料ガス吸入孔３８と、前記吸入側マニホールド３３が接続される反応ガス吸入口３２とが設けられている。略直方体の電圧変換器５０は、燃料電池３０の車体前方側において、左右一対のメインフレーム２に挟まれるように車幅方向中央に配設されている。また、電圧変換器５０の天面には、金属等で形成された多数の薄い板状部材を車体前後方向に立設してなる放熱フィン５０ａが取り付けられている。   FIG. 3 is a top view of the fuel cell vehicle 1. FIG. 4 is a left side view of the fuel cell vehicle 1, and FIG. 5 is a perspective view showing an example of an exterior part of the fuel cell vehicle 1. The same reference numerals as those described above denote the same or equivalent parts. A fuel gas suction hole 38 to which the fuel gas pipe 45 is connected and a reaction gas suction port 32 to which the suction side manifold 33 is connected are provided on the upper portion of the fuel cell 30 disposed in the center in the vehicle width direction. ing. The substantially rectangular parallelepiped voltage converter 50 is disposed at the center in the vehicle width direction so as to be sandwiched between the pair of left and right main frames 2 on the vehicle body front side of the fuel cell 30. In addition, on the top surface of the voltage converter 50, there are attached heat radiating fins 50a formed by standing a large number of thin plate members made of metal or the like in the longitudinal direction of the vehicle body.

図６は、図３のＡ−Ａ線断面図である。前記放熱フィン５０ａは、多数の板状部材５０ｂを車体前後方向に配置して構成されているので、放熱フィン５０ａの向きと走行風の向きとが揃い、放熱フィン５０ａに触れる外気が流れやすくなって冷却効果をさらに高めることができる。また、板状部材５０ｂを互いに連結する基部にも車体前後方向の放熱通風孔５０ｃが形成されており、外気との接触面積が拡大されて、電圧変換器５０の冷却効果がさらに高められる。   6 is a cross-sectional view taken along line AA in FIG. Since the heat radiating fin 50a is configured by arranging a large number of plate-like members 50b in the longitudinal direction of the vehicle body, the direction of the heat radiating fin 50a is aligned with the direction of the traveling wind, and the outside air that touches the heat radiating fin 50a can easily flow. The cooling effect can be further enhanced. Further, the base portion that connects the plate-like members 50b to each other is also formed with a heat radiating vent hole 50c in the longitudinal direction of the vehicle body, so that the contact area with the outside air is expanded, and the cooling effect of the voltage converter 50 is further enhanced.

電圧変換器５０は、前輪ＷＦを操舵する操向ハンドル５と、運転者１００が着座するシート１８との間に形成される跨ぎ部２０の内部に収められている。車幅方向左右に形成される足乗せ部１９に挟まれると共に、足乗せ部１９より一段高い天面を有する跨ぎ部２０は、乗降時に運転者が跨ぎやすいように極力低く形成されるため、自ずと電圧変換器５０と跨ぎ部２０の天面との間隔は小さくなる。したがって、電圧変換器５０および放熱フィン５０ａが車体外部と近い位置に置かれることとなり、電圧変換器５０の冷却効果を高めることが可能となる。また、本実施形態では、前記放熱フィン５０ａが、跨ぎ部２０の天面に形成された窓部から車体外方に臨むように構成されているので、放熱フィン５０ａが外気に直接触れるようになり、冷却効果をより一層高めることができるようになる。   The voltage converter 50 is housed in a straddle portion 20 formed between the steering handle 5 that steers the front wheel WF and the seat 18 on which the driver 100 is seated. Since the straddle portion 20 sandwiched between the footrest portions 19 formed on the left and right sides in the vehicle width direction and having a top surface that is one step higher than the footrest portion 19 is formed as low as possible so that the driver can easily straddle when getting on and off, The space | interval of the voltage converter 50 and the top | upper surface of the crossing part 20 becomes small. Therefore, the voltage converter 50 and the heat radiating fins 50a are placed close to the outside of the vehicle body, and the cooling effect of the voltage converter 50 can be enhanced. Further, in the present embodiment, since the radiating fin 50a is configured to face the outside of the vehicle body from the window formed on the top surface of the straddling portion 20, the radiating fin 50a comes into direct contact with the outside air. The cooling effect can be further enhanced.

本実施形態に係る燃料電池車両１では、樹脂の薄板等で形成された外装部品としてのカウリング１７の内側に、燃料電池３０を冷却する冷却水の放熱器としてのラジエータ６０Ｌ，６０Ｒが配設されており、電圧変換器５０は、左右ラジエータ６０Ｌ，６０Ｒの間に配設されている。これにより、ラジエータを通過した温風が電圧変換器５０に当たるのを防止し、車両正面からの走行風を車幅方向中央に配設された電圧変換器５０に当てることができる。なお、電圧変換器５０の側方を通過する走行風は、放熱フィン５０ａが臨む跨ぎ部の窓部から車体外部に排出するほか、車体後方の燃料電池３０の冷却に利用してもよい。   In the fuel cell vehicle 1 according to the present embodiment, radiators 60L and 60R as cooling water radiators for cooling the fuel cell 30 are disposed inside a cowling 17 as an exterior part formed of a thin resin plate or the like. The voltage converter 50 is disposed between the left and right radiators 60L and 60R. Thereby, it is possible to prevent the warm air that has passed through the radiator from hitting the voltage converter 50 and to apply the traveling wind from the front of the vehicle to the voltage converter 50 disposed at the center in the vehicle width direction. In addition, the traveling wind passing through the side of the voltage converter 50 may be used for cooling the fuel cell 30 at the rear of the vehicle body as well as being discharged to the outside of the vehicle body from the window portion of the straddle portion where the radiating fin 50a faces.

上記したように、本発明に係る燃料電池車両においては、放熱フィン５０ａを有する電圧変換器５０を、操向ハンドル５とシート１８との間に設けられた跨ぎ部２０に、放熱フィン５０ａが上を向くように配設したので、放熱フィン５０ａが車体外部に近い位置に置かれるようになり、簡単な構成によって電圧変換器５０の冷却効果を高めることができるようになる。また、本実施形態に係る燃料電池車両１においては、燃料電池３０やシート下の水素ボンベ１５、駆動モータを内装するスイングアーム１１等の重量物によって、前後輪の重量配分が後輪側寄りになりやすいが、車体前方寄りに位置する跨ぎ部２０に重量物である電圧変換器５０を配設することにより、前輪側の比率を増加させやすくなり、車体の前後重量バランスを向上させることができるようになる。   As described above, in the fuel cell vehicle according to the present invention, the voltage converter 50 having the radiating fin 50a is disposed on the straddle portion 20 provided between the steering handle 5 and the seat 18 so that the radiating fin 50a is located above. Since the heat dissipating fins 50a are placed close to the outside of the vehicle body, the cooling effect of the voltage converter 50 can be enhanced with a simple configuration. Further, in the fuel cell vehicle 1 according to the present embodiment, the weight distribution of the front and rear wheels is closer to the rear wheel side by heavy objects such as the fuel cell 30, the hydrogen cylinder 15 under the seat, and the swing arm 11 that houses the drive motor. Although it is easy to become, the voltage converter 50 which is a heavy article is arrange | positioned in the bridge | crossing part 20 located near the vehicle body front, It becomes easy to increase the ratio of the front wheel side, and can improve the front-back weight balance of a vehicle body. It becomes like this.

なお、電圧変換器、放熱フィン、操向ハンドル、シート、跨ぎ部、外装部品の形状等は、上記した実施形態に限られず種々の変更が可能である。例えば、電圧変換器の放熱フィンは、その一部のみが車体外方に露出するようにしてもよい。   The shape of the voltage converter, the heat radiation fin, the steering handle, the seat, the straddling portion, the exterior part, and the like are not limited to the above-described embodiment, and various changes can be made. For example, only a part of the heat dissipation fins of the voltage converter may be exposed to the outside of the vehicle body.

また、燃料電池車両の形態は、自動二輪車のほか３／４輪車等であってもよく、燃料電池、水素貯蔵手段、過給機、加湿機、二次電池、ラジエータ等の構成部品の形態や配置も種々の変更が可能である。   Further, the form of the fuel cell vehicle may be a three- or four-wheeled vehicle in addition to the motorcycle, and forms of components such as a fuel cell, a hydrogen storage means, a supercharger, a humidifier, a secondary battery, and a radiator. Various changes can be made to the arrangement.
