Abstract
Disclosed herein is a method for estimating a power of a fuel cell. The method includes estimating a predictive current at a predetermined voltage in a controller, based on a present current-voltage characteristic of the fuel cell while the temperature of the fuel cell is being raised, estimating a first power, based on the estimated predictive current and the predetermined voltage, after the step of estimating the predictive current, estimating a second power based on a cell voltage rate while estimating the first power, and calculating an available power of the fuel cell, based on the first power and the second power, after the step of estimating the first power and the step of estimating the second power are performed.
