摘要： A fuel cell system includes an ECU that sets the fuel cell stack to a state of idling stop by lowering both a revolution speed of an air pump and a discharge current value of the fuel cell stack to less than during idling power generation within a range larger than 0, in response to a predetermined idling stop initiation condition having been satisfied during idling power generation. The ECU decreases the discharge current value further as the lowest cell voltage value CV_low of the fuel cell stack decreases so that the lowest cell voltage value CV_low does not fall below a cancellation threshold B, with an event of the lowest cell voltage CV_low of the fuel cell stack having fallen below the cancellation threshold B as a cancellation condition of idling stop.

摘要： A fuel cell system calculates amount of fluid discharged from a fuel gas circulation path with water and fuel gas in accordance with an ordinary process map if inside an anode is not scavenged when a fuel cell stops electrochemical reaction; measures amount of water remaining in a fuel gas circulation path in accordance with cumulative electricity output, temperature, or elapsed time after starting the electrochemical reaction if the inside the anode is scavenged previously; and determines whether the inside the fuel gas circulation path is in dry condition or humid condition. The fuel cell system calculates amount of fluid discharged from the fuel gas circulation path with water or the fuel gas in accordance with a map predetermined for the dry condition if the fuel cell system determines that the inside the fuel gas circulation path is in the dry condition. The fuel cell system calculates the amount of the fluid to be discharged with the water or the fuel gas in accordance with the ordinary map if the fuel cell system determines that the inside the fuel gas circulation path is in the humid condition. Accordingly, wasteful discharge of fuel gas can be prevented in a purging operation after starting up the fuel cell system.

摘要： A controller of a fuel cell system includes an anode gas replacement apparatus, a stoppage time detection apparatus, and a cathode gas flow rate control apparatus. The anode gas replacement apparatus replaces hydrogen in an anode gas channel using an anode gas supply apparatus. The stoppage time detection apparatus detects a stoppage time during which operation of the fuel cell stack is stopped. When the anode gas replacement apparatus replaces the hydrogen, the cathode gas flow rate control apparatus changes the flow rate of the cathode gas supplied from the cathode gas supply apparatus depending on the stoppage time.
