Method of accelerating activation of fuel cell

Abstract

Disclosed is a method of accelerating activation of a fuel cell, which may reduce an activation time of a fuel cell stack and the amount of hydrogen used. The method includes performing a process of alternately repeating allowance and interruption of supply of air to a fuel cell stack, simultaneously with a current application process of applying a high-current load equal to or greater than a predetermined current to the fuel cell stack. This is done while pressurizing hydrogen to a predetermined pressurization set pressure and supplying the pressurized hydrogen to the fuel cell stack to induce pumping of hydrogen to a cathode of the fuel cell stack in a state of interrupting supply of the air.
