摘要: An apparatus for converting power of a fuel cell for power generation to remove an open voltage of the fuel cell when a failure occurs during power generation of the fuel cell and a method thereof are provided. A power converter converts and supplies power generated by the fuel cell to a system or load. A controller detects a failure occurring in the fuel cell, the power converter, or the system or load, while the fuel cell is driven, and reduces an open circuit voltage (OCV) of the fuel cell by a dummy resistor connected with an output terminal of the fuel cell, when the failure occurs in the fuel cell, the power converter, or the system or load. The apparatus removes an OCV of a fuel cell stack to prevent performance and life of the fuel cell from being reduced.

摘要: An apparatus for converting power of a fuel cell for power generation to remove an open voltage of the fuel cell and a method thereof are provided. A power converter converts and supplies power generated by the fuel cell to a system or load. A controller maintains a current linkage to the system or load to reduce an open circuit voltage (OCV) of the fuel cell, after power generation of the fuel cell is ended. The apparatus removes the OCV of the fuel cell to reduce performance and life of the fuel cell, when the fuel cell is stopped.

摘要: An apparatus for converting power of a fuel cell for power generation to remove an open voltage of the fuel cell and a method thereof are provided. A controller links current to a system or load to reduce an open circuit voltage (OCV) of the fuel cell before power generation of the fuel cell is started, after the fuel cell is started. A power converter converts and supplies power generated by the fuel cell to the system or load. The apparatus removes an OCV of a fuel cell stack to prevent performance and life of the fuel cell from being reduced.
