摘要： For implementing a stop control which extracts a current from a fuel cell and consumes a cathode side oxygen at a system stop, the current extraction from the fuel cell is ended in a state that a certain quantity of oxygen smaller than when the current extraction is started remains on a cathode side of the fuel cell. With this, the hydrogen movement to the cathode side after the system stop can be effectively suppressed and thereby a cathode internal hydrogen concentration at the system start can be kept low, thus making it possible to properly process the cathode side hydrogen at the system start.

摘要： Deterioration at the start-up and deterioration during the leaving period are suppressed in a good balance. As a system shutdown process, a controller (30) causes consumption of the air (oxygen) present in an oxidant electrode of a fuel cell stack (1) (oxygen consumption control). Further, after the termination of the oxygen consumption control, the controller (30) performs control to set a medium pressure hydrogen valve (13) and a hydrogen pressure adjustment valve (14) in a closed state. The controller (30) thereby causes hydrogen to be held in a passage located between the medium pressure hydrogen valve (13) and the hydrogen pressure adjustment valve (14). During a system shutdown period, a predetermined amount of hydrogen (medium pressure hydrogen) held in the hydrogen supply passage (L1) at a position between the medium pressure hydrogen valve (13) and the hydrogen pressure adjustment valve (14) can be supplied to the fuel electrode of the fuel cell stack (1) through a bypass passage (L2).
摘要翻译：启动时的恶化和离职期间的恶化得到了很好的平衡。作为系统关闭处理，控制器（30）使燃料电池堆（1）的氧化剂电极中存在的空气（氧气）消耗（氧耗控制）。此外，在氧消耗控制结束之后，控制器（30）进行将中压氢阀（13）和氢压调节阀（14）设定为关闭状态的控制。因此，控制器（30）使氢被保持在位于中压氢阀（13）和氢压力调节阀（14）之间的通道中。在系统关闭期间，在中压氢阀（13）和氢压调节阀（14）之间的位置处保持在氢供给通路（L1）中的预定量的氢（中压氢）可以供给到燃料电池堆（1）的燃料电极通过旁路通路（L2）。

摘要： At system shutdown, supply of hydrogen to a fuel electrode of a fuel cell stack is stopped, and at the same time dry air is supplied to an oxidant electrode. The dry air is subsequently supplied also to the fuel electrode, and finally the system is shut down. This allows optimal conditioning of a fuel cell at system shutdown, and effectively suppresses deterioration of a proton exchange membrane or a catalyst layer of the fuel cell which is caused at system shutdown as well as during storage. Furthermore, a fuel cell system excellent in safety and the like can be provided.
