摘要： A fuel cell system 10 includes a fuel cell 20, gas supply systems 30, 40, which supply gases to the fuel cell 20, and a controller 60, which controls the gas supply systems 30, 40. During a non-operation period of the fuel cell 20, the controller 60 controls the gas supply systems 30, 40 to carry out the scavenging treatment. If the scavenging treatment is interrupted by an operation performed by a user, then the controller 60 controls the gas supply systems 30, 40 and restarts the scavenging treatment after a predetermined time elapses from the interruption.

摘要： Ein Brennstoffzellensystem weist eine Batterie (25) auf, einen Gaszufuhrabschnitt, einen Temperaturerfassungsabschnitt, der so konfiguriert ist, dass er eine angenommene Temperatur (T) erfasst, von der angenommen wird, dass diese während des Betriebsstopps der Brennstoffzelle erreicht wird; und einen Spülsteuerabschnitt. Wenn bestimmt wird, dass die angenommene Temperatur (T) zu der Zeit des Betriebsstopps der Brennstoffzelle (20) bei einer vorbestimmten Temperatur oder darüber liegt, führt der Spülsteuerabschnitt (15) den Stoppzeit-Spülvorgang mit einer ersten Spülleistung durch; und wenn bestimmt wird, dass die angenommene Temperatur (T) niedriger ist als die vorbestimmte Temperatur, führt der Spülsteuerabschnitt (15) den Stoppzeit-Spülvorgang mit einer zweiten Spülleistung durch, die höher ist als die erste Spülleistung.

摘要： An objection is to provide a technology by which a decline in the starting performance of a fuel cell system may be controlled in a low-temperature environment. A control method of a fuel cell system includes a temperature acquisition step of acquiring a temperature of the fuel cell at start-up of the fuel cell; and an exhaust gas control step of restricting, when the temperature of the fuel cell is below a predetermined value, a flow rate of an exhaust gas flowing into a flow path configuring portion that configures at least a part of a flow path of the exhaust gas of the fuel cell as compared to the flow rate of the exhaust gas flowing into the flow path configuring portion when the temperature of the fuel cell is equal to or less than the predetermined value.

摘要： The present invention provides a fuel cell system capable of suppressing the accumulation of impurities in a hydrogen system even when a hydrogen pump stops. A fuel cell system 100 includes a hydrogen pump 4, which is provided in a hydrogen gas circulation flow path 3 and which circulates a hydrogen off-gas discharged from the outlet side of a hydrogen electrode la of a fuel cell 1 to the inlet side of the hydrogen electrode 1a, a discharge valve 61, through which the hydrogen off-gas flowing in the hydrogen gas circulation flow path 3 is discharged out of the hydrogen gas circulation flow path 3, a determination section 81, which determines whether the hydrogen pump 4 is stopped, and a control unit 80, which controls the opening/closing of the discharge valve 61. If the determination section 81 determines that the hydrogen pump 4 has been stopped, then the control unit 80 controls the opening/closing of the discharge valve 61 to increase the discharge amount of the hydrogen off-gas discharged through the discharge valve 61 so as to be greater than the discharge amount of the hydrogen off-gas discharged on the assumption that the hydrogen pump 4 is in operation.

摘要： A fuel cell has: an electrolyte; an anode provided on one side of the electrolyte and having a fuel-gas consuming face at which fuel gas is consumed; a cathode provided on the other side of the electrolyte and having an oxidizing-gas consuming face at which oxidizing gas is consumed; and a fuel-gas passage portion forming a passage through which fuel gas is supplied to predetermined regions of the fuel-gas consuming face of the anode. The fuel cell has an operation mode in which almost the entire amount of the supplied fuel gas is consumed at the fuel-gas consuming face of the anode.
