Description
図1は、本発明の第1実施形態における燃料電池システム100の構成の一例を示す構成図である。
CH3CHO → CH4+CO ・・・(2)
CH3CHO+H2O → 3H2O+2CO ・・・(3)
CO+H2O ⇔ CO2+H2 ・・・(4)
C2H5OH → C2H4+H2O ・・・(5)
CH4+H2O ⇔ 3H2+CO ・・・(6)
図6は、改質器24の流入ガス中の含酸素燃料の濃度と燃料電池スタック10の出力との関係を示す観念図である。
図8は、本発明の第3実施形態における改質器24の運転制御方法に関する処理手順例を示すフローチャートである。
上述の実施形態では図1に示したように改質器24への排ガス供給量が増加するよう排気制御弁42の開度を大きくして改質器24を加熱したが、改質器24を加熱する手法はこれに限られるものではない。そこで本発明の第4実施形態では改質器24を加熱する他の手法について図9を参照して説明する。
上述の実施形態では含酸素燃料濃度の過多に伴う改質器24におけるガス組成の悪化が抑制されるように改質器24の加熱制御を行ったが、改質器24への含酸素燃料ガスの供給量を減らすことでガス組成の悪化を抑制することが可能である。
