1. A method for starting a fuel cell device having a plurality of fuel cells under frost starting conditions, comprising:
establishing a presence of frost starting conditions for the fuel cell device;
anode-side supplying of a hydrogen-containing reactant and cathode-side supplying of an oxygen-containing reactant in a sub-stoichiometric ratio with an oxygen deficit;
maintaining the anode-side supplying of the hydrogen-containing reactant and cathode-side supplying of the oxygen-containing reactant in a sub-stoichiometric ratio for a given interval of time;
after elapsing of the given interval of time, causing complete discharging of the fuel cells in a discharge phase; and
thereafter, converting the fuel cell device to a normal mode with supplying of the reactants according to requirements for a given operating state and power demand.
