  • Patent number: 10340541
    Abstract: An operation control method and system of a fuel cell (stack) are provided and extend the operation field of the fuel cell in a fuel cell electric vehicle and ensure power performance in the initial stage of starting of the vehicle. In an operation control method of a fuel cell having improved reverse voltage durability, in which an oxygen evolution catalyst is added to the anode electrode, a cell voltage of the fuel cell during normal operation of the fuel cell is monitored. The monitored cell voltage of the fuel cell is compared with a first setting voltage. When the cell voltage is less than the first setting voltage as the cell voltage decreases, a fuel cell operation control process for increasing the humidity in a cell of the fuel cell is performed.
