  • PURGING DEVICE AND METHOD FOR IMPROVING COLD-STARTABILITY OF FUEL CELL
    Publication number: 20120123620
    Abstract: The present invention provides a purging device and method for improving cold start performance of a fuel cell by direct heating, in which a gas mixture of hydrogen and air is supplied to a cathode of a fuel cell stack after shutdown of a fuel cell system to generate heat by a reaction of hydrogen and air, and the generated heat is used to increase the temperature of the fuel cell stack and, at the same time, remove water from the fuel cell stack.
