Claims (6)
- 연료전지시스템에 있어서,내부에 촉매층을 구비하고, 반응가스의 공급을 받아 발전을 행하는 연료전지; 및 상기 연료전지에 냉매를 공급하여 상기 연료전지의 온도를 제어하는 냉매시스템을 포함하여 이루어지고,차기 시스템 시동 시 상기 연료전지의 온도 또는 상기 연료전지의 온도와 상관관계를 갖는 온도가 기설정된 온도 이하인 것으로 추정되는 경우, 상기 냉매시스템은 시스템 정지 시 상기 냉매의 공급을 정지시키고, 기설정된 시간의 경과 후에 상기 냉매의 공급을 재개하는 것을 특징으로 하는 연료전지시스템.
- 제1항에 있어서,상기 시스템 정지 시, 상기 연료전지는 상기 연료전지로의 반응가스공급이 차단되는 상태에서 발전을 행하도록 되어 있는 것을 특징으로 하는 연료전지시스템.
- 제1항 또는 제2항에 있어서,상기 냉매시스템은, 상기 연료전지와 상기 연료전지로 공급될 냉매간의 온도차가 기설정된 값 이하가 되도록 상기 연료전지로의 냉매 공급을 제어하는 것을 특징으로 하는 연료전지시스템.
- 제3항에 있어서,상기 냉매시스템은 상기 냉매를 상기 연료전지에 간헐적으로 공급하는 것을 특징으로 하는 연료전지시스템.
- 제1항 내지 제4항 중 어느 한 항에 있어서,상기 연료전지로부터 배출되는 냉매의 온도를 토대로 상기 냉매시스템의 이상을 판정하는 이상판정부를 더 포함하여 이루어지는 것을 특징으로 하는 연료전지시스템.
- 내부에 촉매층을 구비하고, 반응가스의 공급을 받아 발전을 행하는 연료전지; 및 상기 연료전지에 냉매를 공급하여 상기 연료전지의 온도를 제어하는 냉매시스템을 포함하여 이루어지는 연료전지시스템의 운전정지방법에 있어서,차기 시스템 시동 시 상기 연료전지의 온도 또는 상기 연료전지의 온도와 상관관계를 갖는 온도가 기설정된 온도 이하인 것으로 추정되는 경우, 시스템 정지 시 상기 냉매의 공급이 정지되고, 기설정된 시간의 경과 후에 상기 냉매의 공급이 재개되는 것을 특징으로 하는 연료전지시스템의 운전정지방법.
