Abstract
【解決手段】発電停止時にアノード掃気が実施されていない場合には(S100、No)、通常用のマップに基づいてパージ量を算出し(S500)、アノード掃気が実施された場合には(S100、Yes)、燃料電池の積算発電量、温度、発電時間などに基づいて燃料循環路内の水分量を検出し(S200)、燃料循環路内の乾燥状態が解消したかどうかを判断する(S300)。燃料循環路内の乾燥状態が解消していないと判断した場合には(S300、Yes)、アノード掃気後用のマップに基づいてパージ量を算出する(S400)。その後、燃料循環路内の乾燥状態が解消した場合には(S300、Yes)、通常用マップにてパージ量を算出する(S500)。
