1. A system for operating a fuel cell, the system comprising:
a controller configured to derive an output limit value of the fuel cell through an interval average value corresponding to an average of output values of the fuel cell for a designated time and a cumulative average value corresponding to an average of the output values of the fuel cell until a current point in time after starting to operate the fuel cell, and to control operation of the fuel cell based on the derived output limit value.
