Methods and systems of reducing the start-up time for a fuel cell are described. One method of reducing the start-up time includes: concurrently supporting load requests for the fuel cell and stabilizing the voltage of the fuel cell; wherein stabilizing the voltage of the fuel cell comprises: providing a flow of hydrogen to the fuel cell and opening an anode valve, wherein the hydrogen flow continues for predetermined volume or a predetermined time; and ending voltage stabilization after the predetermined volume or predetermined time is exceeded while continuing to support load requests for the fuel cell.
