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： A fuel cell management method includes removing droplets remaining in a fuel cell stack using air supplied to a cathode and hydrogen supplied to an anode. Hydrogen and oxygen remaining are removed in the fuel cell stack by stopping the supply of the hydrogen and the air, and the hydrogen and the oxygen in the fuel cell stack are chemically reacted to remove residual hydrogen and oxygen. Hydrogen is generated in the cathode of the fuel cell stack after removing the residual hydrogen and oxygen. The residual oxygen is additionally removed using the generated hydrogen, the generated hydrogen is absorbed on a surface of a catalyst layer formed on the anode and cathode and accelerating the chemical reaction of hydrogen and air.

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.
