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; a detecting unit for detecting a common power current; and a control unit for detecting an operating point of the fuel cell, and outputting a control signal for varying the output current of the fuel cell on the basis of the position of the detected operating point and detection or non-detection of the common power current.
