    Abstract: The present invention provides a cell or stack for evaluating the performance of a fuel cell and a method of evaluating the performance of the fuel cell using the cell or stack, in which a semiconductor thermoelectric device, attached to the side surface of the unit cell or stack of the fuel cell, is provided so as to evaluate the performance of the fuel cell in an environment in which temperature is maintained at a uniform temperature.According to the present invention, the temperatures of an anode and a cathode of the fuel cell can be precisely changed or maintained. Further, the performance of the fuel cell can also be measured in sub-zero temperature conditions without requiring a separate environmental chamber. A rate of temperature decrease, at which the temperature decreases to a certain sub-zero temperature, or a rate of temperature increase can be precisely controlled. Therefore, the evaluation of the performance of the fuel cell can be easily and precisely achieved in an environmental temperature in which the operation of the fuel cell is required.
