Electric power generation control system and electric power generation control method for fuel cell

A power generation control system for a fuel cell, comprising:

• a chargeable/dischargeable unit connected to a fuel cell, for being charged with electric power from the fuel cell and discharging electric power to a load;
• a target power computing unit for computing a target power to be generated by the fuel cell;
• a power-lowering request detection unit for detecting a power-lowering request to the fuel cell;
• an available power detection unit for detecting available power of the chargeable/dischargeable unit;
• a power extraction limiting unit for limiting electric power to be extracted from the fuel cell based on the power-lowering request detected by the power-lowering request detection unit and the available power detected by the available power detection unit;
• and
• a power extraction control unit for controlling electric power to be extracted from the fuel cell based on the target power computed by the target power computing unit and an output of the power extraction limiting unit,
• wherein, as the power-lowering request detection unit detects a power-lowering request, the power extraction limiting unit reduces electric power to be extracted from the fuel cell by an amount less than the available power of the chargeable/dischargeable unit.
