1. A system for determining performance of a fuel cell stack, the system comprising:
a vehicle configured to collect a voltage of the fuel cell stack and a current of the fuel cell stack; and
a server configured to receive the voltage of the fuel cell stack and the current of the fuel cell stack from the vehicle in real time, determine 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, determine an overall average SOH in the effective current range based on the average SOH of the fuel cell stack for each current section, and determine whether the fuel cell stack has failed based on the overall average SOH,
wherein, when the current of the fuel cell stack received from the vehicle in real time is provided in the current section in effective current range, the server determines instantaneous SOH of the fuel cell based on the current value of the fuel cell stack.
