摘要： While the operation of a fuel cell is stopped, a pressure decrease caused by a current sweep is suppressed from being misjudged as being the occurrence of a hydrogen leak or a cross leak, and the judgment accuracy of the hydrogen leak, etc. is improved. In order to realize this feature, during an intermittent operation, in which, when a load on the fuel cell system is low, electrical power is supplied from a power storage unit in the fuel cell system to a power-consuming apparatus and power generation of a fuel cell is temporarily stopped, in the situation where a current sweep for suppressing a degradation of the fuel cell is performed, a hydrogen pressure in an anode of the fuel cell is corrected based on hydrogen consumed by the current sweep, and a hydrogen leak judgment based on a pressure decrease or a cross leak judgment based on a pressure decrease is performed on the basis of the corrected hydrogen pressure. For example, a pressure decrease speed of the hydrogen pressure in the anode which decreases due to power generation in the current sweep is integrated to obtain the amount of hydrogen pressure decrease caused by the power generation; and the amount of hydrogen pressure decrease can be reflected.

摘要： Even when the atmospheric pressure is lowered, a sufficient amount of oxidant gas is supplied to a fuel cell without causing any failure in a compressor. A control unit judges whether or not both the following conditions are satisfied: the accelerator opening degree detected by an accelerator opening degree sensor is equal to or larger than a predetermined opening degree; and the state where the atmospheric pressure detected by a pressure sensor is equal to or lower than a predetermined pressure value has been maintained for a predetermined time period or longer. If the judgment result is positive, the control unit changes the maximum rotation speed permitted in the compressor from a normal maximum rotation speed to an increased maximum rotation speed. The control unit then judges whether or not a predetermined time period has elapsed from when the maximum rotation speed was changed to the increased maximum rotation speed, and also judges whether or not the state where a discharge temperature of the compressor detected by the temperature sensor is equal to or higher than a predetermined temperature has been maintained for a predetermined time or longer. If the result of at least one of these judgments is positive, the control unit returns the maximum rotation speed to the normal maximum rotation speed.

摘要： In order to prevent the fuel economy from being lowered by a wasteful discharge of fuel gas, in the operation method of a fuel cell system capable of performing intermittent operation for temporarily stopping power generation of the fuel cell, in the case where the secondary pressure of the tank regulator becomes at least a first threshold during intermittent operation, the intermittent operation is stopped and the normal operation is returned. In the case where the intermittent operation is stopped a number of times, subsequent intermittent operation may be prohibited.
