Abstract
A system for determining performance of a fuel cell stack may include a vehicle that collects a current of the fuel cell stack and a current of the fuel cell stack and a server that receives the voltage of the fuel cell stack and the current of the fuel cell stack from the vehicle in real time, determines an average state of health (SOH) of the fuel cell stack for each current section within an effective current range based on the current of the fuel cell stack and the voltage of the fuel cell stack within the effective current range, determines an overall average SOH in the effective current range based on the average SOH of the fuel cell stack for each current section, and determines whether the fuel cell stack has failed based on the overall average SOH.
