摘要： There is provided a fuel cell system which is efficient and does not cause reduction in output even when operation and stopping of a fuel cell are repeated for a long period of time. The fuel cell system is provided with a fuel cell stack including a fuel chamber for supplying a hydrogen gas to a hydrogen electrode and an oxygen chamber for supplying air to an oxygen electrode. The system is provided with gas supply ports for supplying the hydrogen gas into the fuel chamber, gas discharge ports for discharging the hydrogen gas from the fuel chamber, a hydrogen suction pump and the like for sucking the hydrogen gas from the gas discharge ports, a hydrogen circulation pipe and the like for interconnecting the gas discharge ports and the gas supply ports through the hydrogen suction pump and the like, and a first hydrogen discharge pipe and the like for interconnecting the gas discharge ports and an outside gas release port through the hydrogen suction pump and the like.

摘要： A power supply unit operation is switched depending on a load requirement. Namely, when the load requirement is smaller than a predetermined value, operation of a fuel cell system is stopped and electric power is obtained from a secondary battery during an intermittent operation mode. Alternatively, when the load requirement is equal to or larger than the predetermined value, the electric power is obtained from a fuel cell during a steady operation mode. When the electric power is generated by the fuel cell in the steady operation mode, an amount of fuel supplied to the fuel cell is detected, and an operation point of the fuel cell is set in consideration of the fuel amount. However, when the operation mode is switched from the intermittent operation mode to the steady operation mode, and the fuel cell system is activated, the operation point of the fuel cell is set depending on the load requirement without considering the fuel amount until a predetermined time elapses after the activation.
摘要翻译：电源单元操作根据负载要求进行切换。也就是说，当负载要求小于预定值时，停止燃料电池系统的操作，并且在间歇运行模式期间从二次电池获得电力。或者，当负载要求等于或大于预定值时，在稳定运行模式期间从燃料电池获得电力。当在稳定运行模式下由燃料电池产生电力时，检测供给到燃料电池的燃料量，并根据燃料量设定燃料电池的运转点。然而，当操作模式从间歇操作模式切换到稳定运行模式并且燃料电池系统被激活时，根据负载要求设定燃料电池的操作点，而不考虑燃料量直到预定时间激活后经过。
