摘要： A fuel cell system according to the present invention is characterized by comprising a measurement unit which measures an impedance of a fuel cell in a predetermined frequency region, and a regulation unit which regulates an amount of a gas to be supplied to the fuel cell based on a measured value of the impedance in the predetermined frequency region. According to such a constitution, the impedance of the fuel cell in the predetermined frequency region (e.g., a low frequency region) is measured, and the amount of the gas (e.g., an amount of an oxidizing gas) to be supplied to the fuel cell is regulated based on this measured value of the impedance. Here, since the impedance of the fuel cell in the predetermined frequency region largely differs with a fuel supply state (see FIG. 2), the amount of the gas to be supplied to the fuel cell can be regulated based on the measured value of the impedance to realize a highly efficient and stable operation.

摘要： A fuel cell system capable of measuring AC impedance comprises: power generation stabilizing means for stabilizing power generation in a fuel cell, and impedance measuring means for measuring the AC impedance after power generation in the fuel cell has been stabilized. Since the AC impedance in a low frequency range is measured after power generation in the fuel cell is stabilized, no external disturbance occurs during measurement, and the AC impedance can be measured with a high degree of precision. Thus, a fuel cell system and a measuring method with which AC impedance can be measured with a high degree of precision can be provided.

摘要： There is provided a fuel cell system capable of notifying a user that control for low-temperature countermeasure is performed, without any strange feeling and false recognition. When control for low-temperature countermeasure such as scavenging at system termination or warm-up at system start-up is made, the user is reliably notified that the control is performed, by a text message or a speech message. Consequently, even in a situation where the system is operating after an ignition key is turned off, the user suffers neither strange feeling nor false recognition.

摘要： A DC/DC converter includes a reactor, IGBT devices, a dead time generation unit, and a DC-CPU. The dead time generation unit operates in response to a reference signal for a duty ratio, to output first and second activation signals provided with an inactive period corresponding to a dead time preventing both of the IGBT devices from conducting. The DC-CPU corrects a tentative duty ratio calculated as based on a voltage control value, in accordance with a value of a current flowing through the reactor, to output the reference signal. Preferably the DC-CPU associates the value of the current of the reactor with three states and when the value approaches a value at which a state transitions to a different state, the DC-CPU gradually switches a correction value.

摘要： There is disclosed a fuel cell system in which a poisoned electrode catalyst can be recovered while meeting a demand for an output power. When a controller detects that an electrode catalyst is positioned, the controller derives a target operation point adequate for recovering a function of the poisoned electrode catalyst to realize shift of an operation point so that the output power is kept constant. Specifically, an FC voltage is controlled using a DC/DC converter, and an amount of an oxidizing gas to be fed from an oxidizing gas supply source is adjusted, thereby controlling an FC current.
