摘要： A system controller drives a gas circulator with a purge valve closed to supply hydrogen to a fuel cell stack and then increases anode operating pressure and cathode operating pressure to target operating pressures after a predetermined condition is satisfied. This allows an amount of gas mixture of remaining oxygen and hydrogen to be suppressed compared to the case of increasing the anode operating pressure in a state where oxygen remains in the anode circulation path. Accordingly, it is possible to suppress local generation of electric potential and heat and prevent degradation of the components of the fuel cell stack. Moreover, hydrogen is not discharged during activation, which eliminates the need to include dilution equipment of combustion equipment for treating hydrogen and increases the degree of freedom in the layout of the fuel cell system.

摘要： A fuel cell stack includes a heat exchange unit that performs heat exchange between a gas mixture containing source hydrogen and a circulating gas and cooling water used for controlling the temperature of the fuel cell stack. A system controller adjusts the temperature of the cooling water by controlling a temperature control unit on the basis of the temperature of source hydrogen flowing into a junction at which the source hydrogen and a circulating gas are mixed such that the temperature of a source/recirculated hydrogen mixture that is mixed at the junction and that is supplied to the fuel cell stack is kept within a managed temperature range.

摘要翻译：系统控制器驱动气体循环器，其中关闭吹扫阀以向燃料电池堆供应氢，然后在满足预定条件之后将阳极操作压力和阴极操作压力提高到目标工作压力。与在氧气保持在阳极循环路径中的状态下增加阳极工作压力的情况相比，能够抑制余下的氧气和氢气的混合气体的量。因此，可以抑制电位的局部产生和热量，并且防止燃料电池堆的部件的劣化。此外，在活化期间氢气不会排出，这不需要包括用于处理氢气的燃烧设备的稀释设备并且增加燃料电池系统的布局的自由度。

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.
