1. A method for determining a fuel flow through a pulsed device that provides hydrogen fuel from a hydrogen source to an anode side of a fuel cell stack, said method comprising:

  • determining when the device is opened and closeddetermining a pressure of the anode side of the fuel cell stack just before opening the device;

    determining a pressure of the anode side of the fuel cell stack just after closing the device; and

    determining the fuel flow using the difference between the pressure just after closing the device and the pressure just before opening the device.
