Abstract
A system and method for diagnosing a fuel cell includes one or more fuel cell modules each including a fuel cell stack to output power through a first converter and a battery connected to the fuel cell stack through a second converter; and a controller configured to determine whether diagnosis of the fuel cell stack included in the one or more fuel cell modules is required, and to control the one or more fuel cell module to simultaneously or sequentially diagnose the fuel cell stack determined to require diagnosis based on an output demand power of the one or more fuel cell modules.
