Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an operation method for a fuel battery system capable of suppressing reduction in output energy during warm-up operation.SOLUTION: In a warming-up operation of a fuel battery 3 of a fuel battery system 2 that includes a fuel battery 3 capable of outputting electric energy and a battery 40 capable of storing electric energy generated from the fuel battery 3 and outputting electric energy to the outside, when the stored energy amount of the battery 40 is less than a predetermined value, the fuel battery 3 is warmed up without outputting the stored energy of the battery 40 to the outside, and the electric energy generated from the fuel battery 3 is stored in the battery 40, whereas when the stored energy amount of the battery 40 is not less than the predetermined value, the storage energy of the battery 40 is outputted to the outside, the fuel battery 3 is warmed up, and the electric energy generated from the fuel battery 3 is stored in the battery 40.SELECTED DRAWING: Figure 1
【課題】暖機運転中における出力エネルギーの低下を抑制できる燃料電池システムの運転方法を提供すること。【解決手段】電気エネルギーを出力可能な燃料電池3と燃料電池3から生じた電気エネルギーを蓄電可能であり電気エネルギーを外部出力可能なバッテリー40とを備える燃料電池システム2の燃料電池3の暖機運転時において、バッテリー40の蓄電エネルギー量が所定値未満である場合には、バッテリー40の蓄電エネルギーを外部出力することなく、燃料電池3を暖機運転させ、燃料電池3から生じた電気エネルギーをバッテリー40に蓄電し、バッテリー40の蓄電エネルギー量が所定値以上である場合には、バッテリー40の蓄電エネルギーを外部出力するとともに、燃料電池3を暖機運転させ、燃料電池3から生じた電気エネルギーをバッテリー40に蓄電する。【選択図】図1 |
