FUEL CELL MANAGEMENT METHOD

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.

1. A fuel cell management method, comprising steps of:
removing, by a controller, droplets remaining in a fuel cell stack using air supplied to a cathode and hydrogen supplied to an anode; removing hydrogen and oxygen remaining in the fuel cell stack by stopping the supply of hydrogen and air and chemically reacting the hydrogen and oxygen in the fuel cell stack to remove the residual hydrogen and oxygen; generating hydrogen in the cathode of the fuel cell stack after removing the residual hydrogen and oxygen; and additionally removing the residual oxygen using the generated hydrogen and adsorbing the generated hydrogen on a surface of a catalyst layer formed on the anode and the cathode and accelerating the chemical reaction of the air and the hydrogen.
