摘要： An FC voltage increasing converter includes a plurality of converter parts having reactors. Regarding the first of the plurality of converter parts provided with a thermistor, the output starts to be limited when the temperature detected by the thermistor reaches a limitation starting temperature, which is obtained based on a reference heat-resistant temperature, which is obtained by subtracting an error of the thermistor from a specification heat-resistant temperature of each of the reactors. Meanwhile, regarding the second, third and fourth of the plurality of converter parts not provided with thermistors, the outputs start to be limited when the temperature detected by the thermistor reaches a limitation starting temperature obtained based on an allowable temperature, which is obtained by subtracting a characteristic-variation temperature of the reactor from the reference heat-resistant temperature of the reactor.

摘要： When the operation point of a DC/DC converter, which steps up/down the output voltage of a fuel cell stack, is in a range of reduction in response capability and further there is issued a request of determining an AC impedance, a controller switches numbers of the drive phases of the DC/DC converter to determine an AC impedance of the fuel cell stack. If the operation point of the DC/DC converter is in the range of reduction in response capability and further the precision of determining the AC impedance is reduced, then the determination of AC impedance in the range of reduction in response capability is inhibited and the switching of the phases of the DC/DC converter is implemented, thereby causing the operation point of the DC/DC converter to be out of the range of reduction in response capability, with the result that the precision of determining the AC impedance can be raised.

摘要： When a request power for a fuel cell is smaller than a predetermined value, a fuel cell system stops the supply of an oxidizing gas to the fuel cell and lowers the output voltage of the fuel cell from a use upper limit voltage to a reduction voltage to perform catalyst activation processing. When the output voltage of the fuel cell lowers to an air blow voltage because of the shortage of the oxidizing gas, the fuel cell system resupplies the oxidizing gas to recover the output voltage of the fuel cell.

摘要： A fuel cell system capable of reducing time spent before actual execution of low-temperature countermeasure processing is provided. At the time of activation, a control unit for the fuel cell system refers to, for example, a detected FC temperature and judges whether or not the low-temperature countermeasure processing is necessary for the activation. If the control unit determines that the low-temperature countermeasure processing is necessary, it controls an output voltage of the fuel cell to be a target voltage for the low-temperature countermeasure processing, without having the fuel cell enter an OCV state, and then executes the low-temperature countermeasure processing.

摘要： When a power generation instruction value for a fuel cell is reduced during warm-up of the fuel cell by a low power generation efficiency operation as compared to a normal operation and when supply of a reactant gas to the fuel cell cannot be controlled so as to follow the reduction of the power generation instruction value, the reactant gas supply to the fuel cell is reduced and the output voltage to the fuel cell is increased. Thus, it is possible to charge an excessive power equivalent to a difference between a fuel cell generation amount and the power generation instruction value into a capacitance component of the fuel cell, so that the power supplied to the external load of the fuel cell coincides with the power generation instruction value. Thus, when a power request for the fuel cell during the low-efficiency operation is suddenly reduced, it is possible to perform control so that the excessive power is not supplied to the external load.

摘要： There is disclosed a fuel cell system which can control an output current of a fuel cell even if an error occurs in split flow control of an oxidizing gas. The fuel cell system includes a fuel cell and a feed device for supplying the oxidizing gas under pressure to the fuel cell. A feed channel is connected to a discharge channel by a bypass channel so that the oxidizing gas flows while bypassing the fuel cell. The system includes a regulator valve and a bypass valve which adjust the split flow of the oxidizing gas to the bypass channel and the fuel cell. When the regulator valve or the bypass valve has an error, a controller stops the control of the output current of the fuel cell by control of the regulator valve and switches the control to a control of the output current of the fuel cell by control of the feed device.
