Abstract
A method for activating a fuel cell stack without using an electric load includes chemically adsorbing hydrogen into a catalyst of a cathode. Oxygen remaining in the stack is removed to seal and store the fuel cell stack while maintaining a negative pressure in the fuel cell stack. The method for activating a fuel cell stack does not require an electric load device, and therefore does not increase the number of activation equipment, thereby preventing the total production speed of the fuel cell stack from reducing in response to the stack activation.
