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。

摘要： A fuel cell system FC replenishes a fuel cell stack with air or hydrogen by temporarily driving a compressor or a low-pressure valve even during an intermittent operation mode. If air is supplied for replenishment, the amount of air remaining in an air supply system is kept substantially constant, so that the voltage fall during a stop of the fuel cell system can be curbed. If hydrogen is supplied for replenishment, the amount of hydrogen moving to the air supply system is offset, so that a delay in supplying hydrogen can be curbed. Furthermore, the fuel cell system FC inputs signals from a sensor, such as, a brake sensor, a shift selector, or other suitable means and anticipates acceleration of a vehicle equipped with the system FC. On the basis of the anticipation of acceleration, the system FC replenishes the fuel cell stack with air or hydrogen in advance.

摘要： A fuel cell system FC replenishes a fuel cell stack with air or hydrogen by temporarily driving a compressor 41 or a low-pressure valve 24 even during an intermittent operation mode. If air is supplied for replenishment, the amount of air remaining in an air supply system is kept substantially constant, so that the voltage fall during a stop of the fuel cell system can be curbed. If hydrogen is supplied for replenishment, the amount of hydrogen moving to the air supply system is offset, so that a delay in supplying hydrogen can be curbed.

摘要： In a fluid leakage detection apparatus, hydrogen is supplied from a hydrogen tank to an FC stack of a fuel cell via first and second pipes. An inlet valve is provided between the hydrogen tank and the first pipe, and an outlet valve is provided between the first pipe and the second pipe. A controller serves to control valve opening a valve closing operation of the inlet and outlet valves, respectively. Those valves are closed in a state where the pressure within the hydrogen tank is made lower than the pressure within the first pipe, and the pressure within the second pipe is made lower than the pressure within the first pipe by operating those valves. Thereafter, the increase or decrease in the pressure within the first pipe is detected by a pressure gauge such that the leakage in the inlet valve or the outlet valve is determined. This makes it possible to detect the leakage both in the inlet valve and the outlet valve at the same time.

摘要： In a power supply device including a fuel cell unit with a stack of fuel cells or a fuel cell stack and a secondary battery, an intermittent drive mode is selected under a preset condition to receive power supply only from the secondary battery. The control procedure of the invention determines whether a temporary stop of the fuel cell stack or continuance of the stop of the fuel cell stack leads to potential performance deterioration of the fuel cell stack at a restart of the fuel cell unit. In response to estimation of the potential performance deterioration, the control procedure controls the power supply device to continue or start power generation of the fuel cell stack, regardless of selection of the intermittent drive mode under the preset condition.
