Description
(2)上記形態の燃料電池システムであって、さらに、前記冷媒回路に設けられ、前記冷媒に含まれる不純物イオンを交換するイオン交換器を備え、前記絶縁抵抗値検出部は、前記イオン交換器に前記冷媒を通じさせない状態で前記絶縁抵抗値を検出し、その後、前記イオン交換器に前記冷媒を通じた状態で前記絶縁抵抗値を検出し、前記絶縁抵抗値が低下した値から復帰した場合には、前記タンクに前記絶縁抵抗値を低下させる誤った冷媒が補充されたことに起因する前記絶縁抵抗値の一時的な低下と判定するようにしてもよい。この形態によれば、絶縁抵抗値の一時的な低下の原因が、絶縁抵抗値を低下させる冷媒がタンクに誤って補充されたものか否かを判定できる。
(3)本発明は、燃料電池システム以外の種々の形態で実現することも可能である。例えば、燃料電池システムにおける漏電検出方法の製造方法や誤冷媒補充検出方法等の形態で実現することができる。
