Abstract
Description
図1は、本開示の一実施形態における燃料電池システム100の概略構成を示す図である。燃料電池システム100は、燃料電池スタック10と、制御部20と、カソードガス供給部30と、アノードガス供給部50と、冷却媒体循環部70と、を備える。また、燃料電池システム100は、DC/DCコンバータ80と、パワーコントロールユニット(以下、「PCU81」という)81と、負荷82と、電圧測定部83と、電流計84とを備える。本実施形態の燃料電池システム100は、例えば、燃料電池車両に搭載される。
(B1)上述した実施形態において、制御部20は、スタック温度Tfcが第2閾値温度Tth2以上の場合に、スタック温度Tfcが第2閾値温度Tth2より低い場合よりも、目標温度Taおよび設定発熱量Jaを小さく設定する。この代わりに、制御部20は、スタック温度Tfcが第2閾値温度Tth2以上の場合に、スタック温度Tfcが第2閾値温度Tth2より低い場合よりも、目標温度Taと設定発熱量Jaとのうちいずれか一方を小さく設定すればよい。例えば、制御部20は、スタック温度Tfcが第2閾値温度Tth2以上の場合に、目標温度Taを温度T1に設定し、設定発熱量Jaを熱量J2に設定する。また、制御部20は、スタック温度Tfcが第2閾値温度Tth2より低い場合に、目標温度Taを温度T2に設定し、設定発熱量Jaを熱量J2に設定する。
