Field
The present invention relates to a fuel cell system and an air system abnormality determination method.
Related Art
As described in JP 2012-4138A, for example, in a conventional fuel cell system, upon determination that a fuel cell is in transient operation, a target pressure value of the air as an oxidizing gas is increased to be higher than a target pressure value during ordinary operation. This suppresses a significant reduction in output voltage of the fuel cell in the case where the air supply system has an abnormality and thus allows the operation of the fuel cell to be continued stably.
