Abstract
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.
