Description
図1は燃料電池車両の車載電源システムとして機能する燃料電池システム10のシステム構成を示す。
(1/2)O2+2H++2e- → H2O …(2)
H2+(1/2)O2 → H2O …(3)
コントローラ60は、まず、待機モードにある(ステップ101)。この待機モードは、起動信号IGがオフになっている期間中、継続する(ステップ102;NO)。一方、起動信号IGがオンになると(ステップ102;YES)、コントローラ60は、燃料電池スタック20の出力特性マップ80の初期値を設定する(ステップ103)。この初期値設定では、燃料電池スタック20の出力電流ゼロに対応する出力電圧として、開放端電圧(OCV)が設定される。
