- a power cord 282 is further electrically connected in parallel with the power cable 259 at the rear portion of the converter assembly 250.
- the power cord 282 is connected to the inverter 93 shown in FIG. 1 by a power plug 283 provided at the tip.
- the bottom surface protection plate 262 is a protection means for protecting the FC converter 90 from the impact of a collision from the lower side of the vehicle, that is, from the bottom surface.
- the bottom surface protection plate 262 is provided with an attachment portion 263 on the rear side of the vehicle and an attachment portion 265 on the front side of the vehicle.
- the attachment portions 263 and 265 are members that hold the bottom surface protection plate 262 at four diagonal points, and have a bent structure as illustrated.
- the attachment portions 263 and 265 of the bottom surface protection plate 262 are related to the second feature of the present invention so that the attachment portion 265 provided on the front side is released with a weaker force than the attachment portion 263 provided on the rear side. It is configured.
- the fastening groove 266 of the mounting portion 265 on the front side of the vehicle is open in the front direction of the vehicle, whereas the fastening groove 264 of the mounting portion 263 on the rear side of the vehicle is open in the vehicle width direction. Therefore, when an impact is applied to the converter assembly 250 from the front side of the vehicle, the fastening groove 266 of the mounting portion 265 on the front side of the vehicle is more easily disengaged from the fastening of the bolt 281 than the fastening groove 264 of the mounting portion 263 on the rear side of the vehicle. It is easy.
- the front protective plate 270 is a protective means shaped so as to cover the inclined portion 256 provided on the lower part of the front surface 255 of the FC converter 90.
- the inclined portion 256 according to the first feature of the present invention is formed in front of the lower housing 252 of the FC converter 90.

図3に本実施形態1における燃料電池システムの配置を含む車両底面図を示す。以下に説明するフレームやメンバー、ピラー等の各種部材は、一定の剛性を有する金属材料、例えば、アルミニウム、SUS、鉄等で構成されるものとする。金属材料は、加工の容易さ、強度、耐性、重量、コスト等の観点から任意に選択可能である。金属材料に公知の硬化処理、例えば焼き入れや合金化を図ってもよい。
図4に示すように、車両走行用モーター94は、取付ゴム131を介して、フロントサスペンションメンバー112に設けられたモーターマウント130に締結されている。車両前方からの衝突の衝撃が加わると、車両走行用モーター94が後退し、フロントサスペンションメンバー112が後退する。しかしながら、本発明の関連装置としての後述する構成をコンバーターアセンブリ250が備えているので、燃料電池アセンブリ200を衝突の衝撃から保護するように構成されている。図2でも前述したように、ダッシュボード105の車両中央部に設けられたトンネル部109の内部に、コンバーターアセンブリ250および燃料電池アセンブリ200が配置されている。サイドロッカーメンバー128(129)の前方からはフロントピラー106が立設し、中央部からはセンターピラー107が立設している。リヤロッカーメンバー146の中央部からはリヤピラー108が立設している。図3で前述したように、サイドロッカーメンバー128および129は、第1クロスメンバー126、第2クロスメンバー132、第3クロスメンバー136により、コンバーターアセンブリ250および燃料電池アセンブリ200を囲む骨格構造が構成されている。

図5に示すように、燃料電池アセンブリ200は、保護構造体220に燃料電池ユニット201が設置されて構成されている。
図5~図7を参照しながら、コンバーターアセンブリ250の構造を詳しく説明する。図6は、コンバーターアセンブリ250の上側からの斜視図である。図7は、コンバーターアセンブリ250の下側からの斜視図である。
図8および図9を参照しながら、本実施形態の構造によって奏する特徴的な機能を説明する。
本発明の第1の特徴は、燃料電池ユニット201に隣接して設置される関連装置であるFCコンバーター90に、車両前側に傾斜部256を備えたことである。この構造によれば、車両前側から車両100に衝突の衝撃が加わった場合に、FCコンバーター90の移動方向が前進方向と平行ではない方向、すなわち下方向に変更されるのである。図8を参照して説明する。
本発明の燃料電池システムの第2の特徴は、関連装置であるコンバーターアセンブリ250において、底面保護プレート262の前側に設けられる取付部265が後側に設けられる取付部263よりも弱い力で締結が解除されるように構成されていることである。
本発明の燃料電池システムの第3の特徴は、関連装置であるFCコンバーター90の後部、すなわち燃料電池ユニット201側に設けられた突起部258に関する。この突起部258は、車両が衝突した場合において想定されるコンバーターアセンブリ250の移動により、燃料電池ユニット201の電極端子に当接することになる位置に設けられていることを特徴とする。図9を参照して説明する。
本発明の燃料電池システムの第4の特徴は、一定以上の力が加わることにより関連装置であるFCコンバーター90の電源を短絡可能に構成されたリレー部257(短絡部)をFCコンバーター90の後部に備えたことである。
(1)本実施形態における第1の特徴によれば、コンバーターアセンブリ250の前側に傾斜部256を備えている。かかる構成により、車両前側から衝突の衝撃が加わった場合に、先に衝突の衝撃を受けるフロントサスペンションメンバー112や車両走行用モーター94の移動方向を下側に変更可能であり、燃料電池ユニット201の破損を防止することが可能である。
本発明の実施形態2は、本発明の第1の特徴の変形例に関する。
上記実施形態1では、燃料電池アセンブリ200の前側にコンバーターアセンブリ250を配置し、FCコンバーター90に本発明の第1の特徴、すなわち傾斜部256を設けた。本実施形態2では、FCコンバーター90以外の関連装置に本発明の第1の特徴を設けるものである。
本実施形態2では、冷却液ポンプ35が本発明における第1の特徴として機能する。すなわち、車両前側から車両100に衝突の衝撃が加わった場合に、フロントサスペンションメンバー112等の関連装置の移動方向が前進方向と平行ではない方向、すなわち下方向に変更されるのである。図13を参照して説明する。
本発明の実施形態3は、上記実施形態2の変形例に関する。
図14に本実施形態3における燃料電池アセンブリ300bの車両側面図を示す。図14に示すように、本実施形態3の燃料電池アセンブリ300bは、保護構造体310に後側構造体320および前側構造体330が設けられている点で、上記実施形態2と共通している。
本発明は上記実施形態に限定されることなく種々に変形して適用することが可能である。
このように構成すれば、前側から衝突の衝撃を受けた場合に、フロントサスペンションメンバー112はコンバーターアセンブリ250の下側に入り込む。よって、燃料電池ユニット201と衝突しない程度にフロントサスペンションメンバー112の移動方向を変更することが可能である。
