Description
本実施形態1は、電気自動車等の移動体に搭載する燃料電池システムに、本発明の発電停止制御方法を適用したものであり、特に間欠運転の発電停止期間に本発明の発電停止制御を適用したものである。
2H++2e-+(1/2)O2 → H2O …(2)
燃料ガス系統10は、水素ガス供給源としての水素タンク11、元弁SV1、調圧弁RG、燃料電池入口遮断弁SV2、燃料電池スタック10を経て燃料電池出口遮断弁SV3、気液分離器12及び遮断弁SV4、水素ポンプ13、並びに逆止弁RVを備えている。
本実施形態にかかる間欠運転モードは、軽負荷時に燃費を向上させる運転方法であり、一定期間の燃料電池による発電と一定期間の発電停止とが繰り返されるモードである。本発明の停止制御は、この間欠発電の発電停止期間において適用される。すなわち、間欠運転時の燃料電池スタック1の発電停止期間において、燃料電池スタック1において酸欠や熱劣化を生じない最低酸素供給量以上の空気(酸化ガス)の供給量が維持される。
上記実施形態1では燃料電池が発電期間から発電停止期間に入る際に、発電期間の空気供給量から制限された空気供給量に急に変化させていたが、本実施形態2では徐々に空気供給量を変化させるものである。当該実施形態は、実施形態1と同様の構造で実施されるものとする。
上記実施形態1では燃料電池が発電停止期間における制限された空気供給量を一定にしていたが、本実施形態3は、断続的に空気供給量を変化させる例に関する。当該実施形態は、実施形態1と同様の構造で実施されるものとする。
本発明は上記各実施形態に限定されることなく種々に変更して利用することができる。例えば、燃料電池の発電停止期間における空気供給量を、制限領域に維持する制御方法には種々の方法が考えられ、そのために検出すべき物理量も変更可能である。コンプレッサの制御タイミングや制御量も上記各実施形態には限定されない。
