    摘要： A method for recovering performance of a degraded polymer electrolyte fuel cell stack through electrode reversal. In detail, oxide films formed on the surface of platinum of a cathode is removed through an electrode reversal process that creates a potential difference between an anode and the cathode by supplying air to the anode instead of hydrogen and supplying a fuel to the cathode instead of air, thus rapidly recovering the performance of a degraded polymer electrolyte fuel cell stack.

    摘要： A method for activating a stack of a fuel cell is provided. The method includes supplying oxygen and hydrogen to the stack after starting an activation process to change the stack to an open circuit voltage (OCV) state and terminating the supply. Adjacent cells of the stack are electrically connected by a cell voltage sensing terminal board and the adjacent cells are shorted to allow a cell voltage to be 0V. Additionally, oxygen and hydrogen are resupplied to the stack and predetermined current density is applied for a predetermined time is executed. The voltage is again decreased to be 0V by applying current density exceeding the predetermined current density for a time exceeding the predetermined time through the open circuit voltage state to remove oxygen remaining in the stack. Oxygen and hydrogen are resupplied after a silent period has elapsed for a predetermined time after removing the remaining oxygen.

    摘要： Disclosed is a pre-activation method for a fuel cell stack, which can reduce the amount of hydrogen used and the processing time required during the regular activation process for the fuel cell stack. The disclosure provides, in part, a pre-activation method including: injecting water droplet-containing, humidified hydrogen into a cathode inlet manifold of a fuel cell stack assembled in an assembly process such that the water droplet-containing hydrogen is supplied to a cathode of the fuel cell stack; and sealing and storing the resulting fuel cell stack for a period of time to pre-activate the fuel cell stack.

    摘要： A method for recovering the performance of a fuel cell stack mounted within a vehicle is provided. A method includes a recovery process of continuously applying a predetermined load using a load device when an air supply is stopped and hydrogen is supplied to a fuel cell stack to output current from the fuel cell stack. Further, protons and electrons generated by hydrogen oxidation reaction at an anode are moved to a cathode, to produce hydrogen at the cathode and simultaneously remove oxide on the catalyst surface of the cathode.
