Fuel cell system
A fuel cell system (10) outputs a valve opening command signal to a first on-off valve (122) and outputs a valve closing command signal to a second on-off valve (164) when a fuel cell stack (18) is stopped and an oxidant gas does not flow into an oxidant supply flow path (60), and then outputs a val...

| Zusammenfassung: | A fuel cell system (10) outputs a valve opening command signal to a first on-off valve (122) and outputs a valve closing command signal to a second on-off valve (164) when a fuel cell stack (18) is stopped and an oxidant gas does not flow into an oxidant supply flow path (60), and then outputs a valve closing command signal to the first on-off valve (122) and a valve closing command signal to the second on-off valve (164). The detection result of the fuel gas by the gas sensor (204) is monitored.
本发明涉及燃料电池系统，在燃料电池堆(18)停止运转并且氧化剂气体没有流到氧化剂供给流路(60)的情况下，燃料电池系统(10)在向第一开闭阀(122)输出阀开放指令信号并且向第二开闭阀(164)输出阀闭锁指令信号之后，监视气体传感器(204)对燃料气体的检测结果。 |
