Abstract:
1. A fuel cell system comprising: a controller including an inhibition system and first, second, and third determination systems; a fuel cell which generates a power by use of a fuel gas and an oxidizing gas; and an air compressor for adjusting an amount of the oxidizing gas to be supplied to the fuel cell under control of the controller; the controller programmed to: feed back a deviation between the target current and an actually measured current of the fuel cell to a change amount of the actually measured voltage of the fuel cell to determine a target voltage value with the third determination system, wherein the controller is programmed to stop the supply of the oxidizing gas from the air compressor in a case where an output voltage of the fuel cell is lowered from the vicinity of an opened circuit voltage to a voltage at a low-efficiency operation point with the inhibition system.
