- connection location between the receptacle 12 and the filling nozzle 23 is below freezing by filling the cooled fuel gas, freezing at the connection location between the receptacle 12 and the filling nozzle 23 is suppressed. Can do.
- the receptacle 12 and the filling nozzle 23 during the filling operation can be used even in the case where rain easily falls into the fuel gas filling position of the gas fuel vehicle 1. Can be prevented from being frozen, and the fuel gas can be smoothly filled in the gas fuel vehicle 1. Therefore, even a user who is not skilled in the filling operation can easily perform the operation of filling the fuel gas vehicle 1 with the fuel gas.
- a fuel cell vehicle equipped with a fuel cell that generates power using fuel gas made of hydrogen gas has been described as an example.
- the present invention is a fuel cell vehicle as long as it is a gas fuel vehicle that travels using gas as fuel. Not limited to.
Abstract
Description
また、前記カバーが、前記ガスステーションのノズルに設けられても良い。この場合、前記カバーは、円筒状をなすと共に前記ノズルの先端部外縁から軸方向外方へ延在するように取り付けられていてもよい。
2 ガスステーション
11 充填口
12 レセプタクル
13,61,72 カバー
23 充填ノズル(ノズル)
34,62 水抜き孔
100 ガス充填システム
図1は、燃料ガスと酸化ガスとの電気化学反応によって発電する燃料電池をエネルギ源として搭載した燃料電池車両などのガス燃料車両1と、このガス燃料車両1に燃料ガスを充填するガスステーション2と、を備えてなるガス充填システム100を示している。
次に、本発明の第1実施形態について説明する。以下の説明において、図1と同一または同様の構成部分については、同一符号を付して詳細な説明を省略する場合がある。
なお、赤外線通信器52は、レセプタクル12の中間部に形成されたフランジ部51に取り付けられていてもよいが、かかる場合には、赤外線通信器52と赤外線通信器53とが相互に何の障害物もなく対向するように、例えば底板部42の一部を中抜きする等の構成にしておく。
かかる特殊事情がある場合においても、本実施形態によれば、充填作業中におけるレセプタクル12と充填ノズル23との凍結による固着を抑制することができ、燃料ガスを円滑にガス燃料車両1へ充填することができる。したがって、セルフ式のガスステーション2が普及し、充填作業に熟練していない不特定多数の利用者が充填作業を実施する場合であっても、ガス燃料車両1への燃料ガスの充填作業を容易に行うことができる。
次に、第2実施形態について説明する。なお、第1実施形態と同一構成部分は、同一符号を付して説明を省略する。
次に、本発明の第3実施形態について説明する。
