Power controlling apparatus for fuel cell system and method thereof

A power controlling apparatus for a fuel cell system, comprising:

• a fuel cell controller which:
• analyzes power state information of a fuel cell system and transmits a power state information signal in accordance with the analysis, the power state information indicative of an amount of power of the fuel cell system, and
• receives a load request power information signal, analyzes the received load request power information signal, and generates a first control signal to change an amount of power to be output from the fuel cell system based on the analysis of the received load request power information signal;
• and
• a power conversion controller which is configured to:
• transmit the load request power information signal to the fuel cell controller based on power information requested by a load, and
• analyze the power state information signal transmitted by the fuel cell controller, and generates a second control signal to control a power conversion amount based on the analysis of the power state information signal.
