This abstract first appeared for US patent application 20250070200 titled 'METHOD OF ACCELERATING ACTIVATION OF FUEL CELL

Original Abstract Submitted

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.
