  • Fuel cell startup apparatus and method
    Patent number: 9742016
    Abstract: A fuel cell startup apparatus and method reduces high-voltage generation and corrosion of a cathode electrode that may occur because the density of oxygen is locally high in a cell near a central flow distributor after long-term parking of a fuel-cell vehicle. To this end, density control gas is selectably injected into a fuel supply line prior to supply of reaction gas of hydrogen and air in a fuel cell startup process after long-term parking to forcedly mix anode-side gas in the fuel supply line and the cell with the density control gas.
