摘要： A fuel cell system includes a fuel cell, a fuel gas passage, and an oxidant gas passage. The fuel cell includes a solid polymer membrane, a fuel electrode, and an oxidant electrode. A coolant flows into the fuel cell via a coolant passage to adjust a temperature of the fuel cell. An oxidant gas outlet temperature detector is configured to detect an outlet temperature of an oxidant gas discharged from an outlet of the oxidant gas passage. A coolant temperature detector is configured to detect a temperature of the coolant passing through an inlet or an outlet of the coolant passage. A dry-up controller is configured to decide that the solid polymer membrane is in a dry-up state when a temperature difference between the temperature of the coolant and the outlet temperature of the oxidant gas exceeds a first threshold value.

摘要： A fuel cell system for a vehicle includes a fuel cell, a fuel supply device, an oxidizer supply device, an anode potential measuring device, and a discharge controller. The anode potential measuring device is configured to measure an anode potential of an anode. The discharge controller is configured to control discharge of electric current from the fuel cell as part of a process of stopping the fuel cell during idling of the vehicle. When receiving idle stop permission for the fuel cell, the discharge controller determines whether the fuel cell is permitted to discharge. When the anode potential is equal to or lower than a predetermined threshold value, the discharge controller permits the fuel cell to discharge. When the anode potential is higher than the predetermined threshold value, the discharge controller does not permit the fuel cell to discharge.
