Description
本発明の一つの形態によれば、車室と、前記車室よりも前方に位置するフロントルームと、を有する燃料電池車両が提供される。この燃料電池車両は、前記フロントルーム内に配置された燃料電池と、前記フロントルーム内において前記燃料電池の下方に配置された、前記燃料電池にカソードガスを供給するエアコンプレッサと、前記フロントルーム内において前記燃料電池よりも下方に配置された、前記燃料電池に冷媒を供給する冷媒供給ポンプと、を備え、前記冷媒供給ポンプは、前記エアコンプレッサの前方に配置されている。また、この燃料電池車両は、さらに、前記フロントルーム内において前記燃料電池よりも下方に配置された、前記エアコンプレッサから送り出された前記カソードガスを冷却するインタークーラを有し、前記インタークーラは、前記エアコンプレッサの後方に配置されている。この形態によれば、エアコンプレッサの前方に冷媒供給ポンプが配置されているので、燃料電池車両が前方衝突した場合に、前方側(例えば、冷媒供給ポンプよりも前方側に位置する燃料電池車両の部品)からエアコンプレッサに加わる衝撃を冷媒供給ポンプによって緩和できる。これにより、エアコンプレッサが損傷する可能性を低減できる。またこの形態によれば、エアコンプレッサの前方に冷媒供給ポンプが配置されているので、燃料電池車両が前方衝突した場合に、前方側(例えば、冷媒供給ポンプよりも前方側に位置する燃料電池車両の部品)からエアコンプレッサに加わる衝撃を冷媒供給ポンプによって緩和できる。これにより、エアコンプレッサが損傷する可能性を低減できる。
図1は、本発明の一実施形態としての燃料電池車両500の概略構成を断面視にて示す説明図である。図1では、燃料電池車両500の幅方向LHの所定位置での、車両の前方FDに向かう前方方向および後方RDに向かう後方方向に沿った断面を表している。本実施形態では、前方方向および後方方向に沿った方向を「前後方向FRD」と呼ぶ。燃料電池車両500は、燃料電池101を電力源として搭載し、動力源であるモータMを駆動することにより、後輪RWが駆動される。なお、図1では、燃料電池車両500の幅方向LH、前方FDに向かう前方方向、および後方RDに向かう後方方向に加えて、重力方向、すなわち、鉛直下方Gを図示している。図1における各方向を示す符号および矢印は、他の図における各方向を示す符号および矢印に対応する。
なお、この発明は上記の実施例や実施形態に限られるものではなく、その要旨を逸脱しない範囲において種々の態様において実施することが可能であり、例えば次のような変形も可能である。
上記実施形態において、インタークーラ35はエアコンプレッサ30の後方RDに配置されていなくてもよい。また、上記実施形態において、エアコンプレッサ30は、前後方向FRDについて、第1部分302が第2部分303よりも後方RD側に位置していなくてもよく、例えば、長手方向LDと幅方向LHとが平行であってもよい。また、上記実施形態において、アノードオフガス循環ポンプ27は、燃料電池車両500を前方FD側から見たときに、タンク20と全てが重なっていてもよいし、タンク20と全てが重なっていなくてもよい。またエアコンプレッサ30、冷媒供給ポンプ40、アノードオフガス循環ポンプ27、エアコンコンプレッサ50のうちで、燃料電池車両500からの要求によって印加される最大電圧が最も高い要素は、エアコンプレッサ30でなくてもよい。このようにしても、エアコンプレッサ30の前方FDに冷媒供給ポンプ40が配置されているので、燃料電池車両500が前方衝突した場合に、前方FD側からエアコンプレッサ30に加わる衝撃を冷媒供給ポンプ40によって緩和できる。
