Abstract
Description
[燃料電池車の燃料電池システム100]
まず実施形態の燃料電池車FCVに搭載される燃料電池システム100の構成について、図1を参照しながら説明する。
図2は、マグネットフィルタ34の概略構成を示す模式図である。図3は、図2におけるA-A’断面図である。
以上説明した本実施形態における燃料電池システム100によれば、磁力を利用した簡易な構成により燃料電池10に悪影響を及ぼし得る異物の除去性能を維持することが可能となっている。
次に図8を参照しつつ、第2実施形態における燃料電池車の燃料電池システム200について説明する。なお、以降で説明する各実施形態および変形例においては、上記した第1実施形態と同じ機能の構成については同一の番号を付すとともに適宜その説明は省略する。
なお、制御装置70と各装置との通信は、例えば、CAN(Controller Area Network)通信を用いて実現される。
以下に、マグネットフィルタ34に付着した鉄粒子Feの清掃方法について説明する。
第1実施形態の燃料電池システム100において、マグネットフィルタ34に付着した鉄粒子Feを清掃する場合には、中空の楕円柱磁性体34aの内部に挿入された永久磁石34cを抜き去ることにより、付着した鉄粒子Feを容易に脱落させることが可能である。本実施形態では、鉄粒子Feを捕捉するために電磁石ではなく永久磁石を使用しているため、車両電源のオフにより捕捉した鉄粒子Feを脱落させることがない。そのため、意図しない鉄粒子Feの放出により燃料電池の寿命特性が低下することを回避できる。
以下に、本実施形態の燃料電池システム200におけるマグネットフィルタ34に付着した鉄粒子Feを除去すべき時期(清掃時期)の予測方法について説明する。なおこの予測方法は、楕円柱磁性体34aと円柱磁性体棒34bとの間で電気的な導通が確立された後で、上記した制御装置70によって以下に示す手順で実行される。
