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： A fuel cell system can be initiated in shorter time while minimizing the deterioration of a fuel cell. The fuel cell system includes a fuel cell stack having a fuel electrode, an oxidizer electrode and an electrolyte membrane disposed there between, the fuel cell producing electricity by an electrochemical reaction of a fuel gas and an oxidizer gas, which are supplied to the fuel electrode and the oxidizer electrode, respectively; a fuel gas supplying device for supplying the fuel gas to the fuel cell stack; an oxidizer gas supplying device for supplying the oxidizer gas to the fuel cell stack; a current controlling device for extracting a current from the fuel cell stack; and a voltage sensor disposed in at least two of the fuel cell stacks. A controller controls the current controlling device such that a minimum voltage, which is obtained from the voltage sensor after a fuel gas is supplied to the fuel electrode without supplying the oxidizer gas to the oxidizer electrode at the time of initiating, becomes zero volts or more. Then, the oxidizer gas is supplied to the oxidizer to start producing electricity.

摘要： A fuel cell system that has a fuel cell stack with a plurality of laminated cells, each of the laminated cells includes an electrolyte membrane interposed between a fuel electrode receiving a supply of fuel gas and an oxidizing agent electrode receiving a supply of oxidizing agent gas. A fuel gas supply device supplies a fuel gas to the fuel electrode. An oxidizing agent gas supply device supplies an oxidizing agent gas to the oxidizing agent electrode. A fuel electrode side discharge system discharges a discharge gas from the fuel electrode to an external. A circulation device re-circulates the discharge gas discharged from the fuel electrode into an upstream side of the fuel electrode. A voltage limit device limits a voltage across the fuel cell stack by drawing a current from the fuel cell stack at a time of an activation of the fuel cell system. A controller halts the supply of the oxidizing agent gas to the oxidizing agent electrode from the oxidizing agent gas supply device at the time of the activation of the fuel cell system, inhibits a discharge of the discharge gas to the external through the fuel electrode side discharge system, and starts the supply of fuel gas to the fuel electrode from the fuel gas supply device in a state where the discharge gas is circulated through the circulation device.

摘要： A fuel cell system has a purge valve that adjusts the amount of nitrogen in a hydrogen circulation channel and a fuel electrode to be discharged through a discharge channel. A purge rate correcting unit variably sets a target control value of the nitrogen content in the hydrogen circulation channel and the fuel electrode by taking into account whether a driving mode is set in a normal power generation mode or an idle mode. An opening of the purge valve is controlled on the basis of the target control value.

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.
