NOVELTY - A stabilizing apparatus comprises a converter (120) for transforming direct current generated from fuel cell (110) into electric power output, where voltage of the electric power output is stable; a direct voltage detector (150) for detecting a direct voltage of the direct current; and a regulating module (260) for regulating electric current of the electric power output based on the direct voltage of the direct current.    USE - A stabilizing apparatus for fuel cell.    ADVANTAGE - The direct voltage detector can detect a direct voltage of the direct current. The regulating module can regulate an electric current of the electric power output based on the direct voltage of the direct current.    DETAILED DESCRIPTION - A stabilizing apparatus comprises a converter (120) for transforming direct current generated from fuel cell (110) into electric power output, where voltage of the electric power output is stable; a direct voltage detector (150) for detecting a direct voltage of the direct current; and a regulating module (260) for regulating electric current of the electric power output based on the direct voltage of the direct current. The apparatus further comprises voltage determining module (210) for determining whether the direct voltage of the direct current exceeds a protective voltage of the fuel cell; a unit for turning off the converter when the direct voltage of the direct current is less than the protective voltage of the fuel cell; a calculator for calculating a protective period when the direct voltage of the direct current exceeds the protective voltage of the fuel cell; and rebooting module (225) for rebooting the converter after the protective period. An INDEPENDENT CLAIM is included for a method for stabilizing a fuel cell.    DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of an apparatus for stabilizing a fuel cell.
