Abstract:
    The present invention discloses a power supply apparatus and method for a line connection type fuel cell system. The power supply apparatus for the line connection type fuel cell system includes: a storing unit for pre-storing a normal region and a warning region according to an operating condition of a fuel cell and a correlation between an output voltage and an output current of the fuel cell; and a control unit for detecting an operating point on the basis of the operating condition of the fuel cell, comparing the detected operating point with the normal region and the warning region, and outputting a control signal for increasing or decreasing the output current of the fuel cell according to the comparison result.
