Zusammenfassung:	A method of predicting a life of a membrane electrode assembly (MEA) of a fuel cell for electric power generation includes: deriving an operating condition for accelerated degradation, which is applicable to the fuel cell; operating the fuel cell for a specific time under the derived operating condition for accelerated degradation and under a normal operating condition, and identifying the degree of degradation of the fuel cell under each of the operating conditions; calculating an acceleration multiple based on the degree of degradation identified under the operating condition for accelerated degradation and under the normal operating condition; and predicting the life of the membrane electrode assembly based on the acceleration multiple.
