Abstract
【解決手段】燃料電池システム10は、燃料電池スタック11と、水素タンク22から水素を供給する水素供給系と、エアコンプレッサにより酸化剤となる空気を供給する酸化剤ガス供給系と、燃料電池のインピーダンスを測定するインピーダンス測定部13と、発電された電力を変換するDC/DCコンバータ14、及び、電力を貯蔵する二次電池15等を含む電気系と、車両を駆動する駆動系50と、を有する。間欠運転で発電が停止した状態からイグニッションスイッチをオフして発電停止となった場合、インピーダンス測定部13は、空気供給が遅れることによる燃料電池セルの過渡状態を避け、空気供給が安定してからインピーダンス測定を実行する。
