Abstract
A fuel cell stack diagnostic system is provided. The system includes a fuel cell stack having a plurality of cell channels and a diagnostic analyzer that performs a voltage measurement on each of the plurality of cell channels. The diagnostic analyzer determines that the voltage measurement is abnormal as a first level when a voltage ratio is less than a first reference voltage ratio when starting a vehicle in which the fuel cell stack diagnostic system is mounted. Additionally, the voltage ratio is a ratio of a minimum cell channel voltage to an average cell channel voltage.
