1. a fuel cell system, comprising:

  • Fuel cell pack, described fuel cell pack comprises anode-side, cathode side, plus end and negative terminal, and described fuel cell pack also comprises the short circuit line being electrically coupled to described plus end and described negative terminal;

    Be electrically coupled to the switch of described short circuit line, described switch can optionally disconnect and close, to provide or to remove the short circuit striding across fuel cell pack;

    Cathode inlet valve, for blocking the cathode flow channels of the porch of fuel cell pack;

    Cathode outlet valve, for blocking the cathode flow channels in the exit of fuel cell pack;

    Hydrogen source, for providing hydrogen to the anode-side of fuel cell pack;

    WithController, for controlling described cathode inlet valve, described cathode outlet valve, described switch and described hydrogen source, described controller side by side or almost side by side carries out following operation;

    Closing Switch, close cathode inlet valve, close cathode outlet valve, and open hydrogen source, make hydrogen be supplied to the anode-side of fuel cell pack, and the air existed in the cathode side of fuel cell pack reacts with the hydrogen of the anode-side that is directed to fuel cell pack, and do not produce voltage due to short circuit.
