摘要： The present invention provides a fuel cell system that controls a pressure for a fuel gas supplied to a fuel cell so that the anode-cathode differential pressure between an anode and a cathode of a fuel cell is maintained within a predetermined range, in order to provide a desired generation amount while reducing the amount of fuel gas discharged to the exterior of the system even if it is difficult to provide an appropriate fuel gas supply amount for a fuel cell load (the generation requirement on the cell). If the system determines that the amount of fuel gas supplied to the fuel cell is less than an appropriate required gas amount for the load (generation requirement) (step S9: NO), for example, if the concentration of nitrogen in the fuel gas reaches a predetermined value or greater, the open and close state of shut-off valves H3, H3A is switched to increase the pressure for the fuel gas supplied to the fuel cell 20 (step S11).

摘要： In a fuel cell system of the invention, a pressure regulator is provided in the pathway of a hydrogen supply conduit that connects a hydrogen tank to a fuel cell stack. An anode off gas discharged from the fuel cell stack is recirculated through a recirculation pipe into the hydrogen supply conduit. A hydrogen pump is provided in the pathway of the recirculation pipe to increase the pressure of the anode off gas. A control unit of the fuel cell system includes a hydrogen pump control module, an abnormality diagnosis module, and an atmospheric pressure-based correction module. The hydrogen pump control module regulates the rotation speed of the hydrogen pump corresponding to a power demand to be output from the fuel cell system. The abnormality diagnosis module detects an abnormal state, based on a result of determination of whether the pressure of the hydrogen supply measured by a pressure sensor is within a certain range defined by two preset threshold values. The atmospheric pressure-based correction module corrects the rotation speed of the hydrogen pump and the threshold values used for abnormality diagnosis according to the atmospheric pressure measured by an atmospheric pressure sensor. Even in the state of unstable output of the pressure regulator with a variation of the atmospheric pressure, such correction compensates for the varying flow rate of the hydrogen supply to the fuel cell stack and thus effectively prevents misjudgment of abnormality diagnosis. Namely the technique of the invention reduces the potential effect of the varying pressure of the hydrogen supply to the fuel cell system with a variation of the atmospheric pressure.

摘要翻译： 在本发明的燃料电池系统中，压力调节器设置在将氢罐连接到燃料电池堆的氢气供应管道的通路中。 从燃料电池堆排出的阳极废气通过再循环管再循环到氢气供应管道中。 在再循环管道的通路中设置氢泵以增加阳极废气的压力。 燃料电池系统的控制单元包括氢泵控制模块，异常诊断模块和基于大气压的校正模块。 氢泵控制模块调节与从燃料电池系统输出的功率需求对应的氢泵的转速。 异常诊断模块基于由压力传感器测量的氢供给压力是否在由两个预设阈值限定的一定范围内的判定结果来检测异常状态。 基于大气压的校正模块根据由大气压力传感器测量的大气压力校正氢泵的转速和用于异常诊断的阈值。 即使在压力调节器的输出不稳定的情况下，这种校正补偿了向燃料电池堆供应的变化的流量，从而有效地防止了异常诊断的误判。 也就是说，本发明的技术降低了随着大气压力变化而对燃料电池系统的氢气供应变化的压力的潜在影响。
