Abstract
Description
図1は、燃料電池システムの一例である。燃料電池システムは、ECU1、燃料電池スタック2、エアコンプレッサ30、インタークーラ31、加湿装置32、インピーダンス測定装置33、冷却装置34、及びポンプ35を有する。また、燃料電池システムは、流量センサ50,56、圧力センサ51,54,57,59、露点センサ52,55、電流センサ53、温度センサ58、酸化剤ガス供給路90、酸化剤ガス排出路92、燃料ガス供給路93、及び燃料ガス排出路94を有する。
図2は、燃料電池の一例を示す断面図である。符号Gaは燃料電池スタック2の積層方向に沿った断面の一部を示す。
符号Gbは、燃料電池スタック2の積層方向から見たアノード流路220〜223の一部を示す。アノード流路220〜223には、例えば、発電により生成された水分である生成水の一部がカソード流路200〜203から移動する。
そこで、ECU1は、アノード流路222,223内の水滴81の詰まりを、アノード流路220〜223の圧力損失Plossの増加とインピーダンスZの増加を判定することにより検出する。
