Abstract

　燃料電池システムにおいては、一定時間の経過ごとに定電流負荷制御部４０１により定電流負荷部２のトランジスタ素子２０１Ｂ、２０２Ｂが動作されて燃料電池発電部１０１よりαアンペア及び２αアンペアの特定電流が出力される。劣化検出部４０２において、αアンペア及び２αアンペアに応じた出力電圧Ｖａ及び出力電圧Ｖｂが求められ、これら出力電圧Ｖａ、Ｖｂの差電圧ｄｖから出力抵抗Rdmfcに相当する傾きＲ（＝ｄｖ／ｄＩ）が求められるとともに、出力電圧Ｖａに電圧差ｄｖを加えた加算電圧値（Ｖａ＋ｄｖ）から開放電圧ＯＣＶが求められ、これら傾きＲ及び開放電圧ＯＣＶが劣化判定部４０３において所定の閾値と比較されて燃料電池発電部１０１の劣化を判定し劣化検出信号が出力される。従って、電池の劣化を検出でき、常に安定して負荷を駆動することができる。
