PURPOSE: An operation control method of a home fuel cell system is provided to improve operation efficiency of a fuel cell by predicting the power and heat quantity according to the used environment, and the required power and heat quantity. CONSTITUTION: An operation control method of a home fuel cell system comprises the steps of: (S01) computing demanded power required for home; (S02) computing demanded quantity of heat required for home; (S03) computing fuel cell generation power generated from a fuel cell(11) according to the computed power and heat; (S04) computing the heat quantity generated from the fuel cell and the heat quantity generated from the fuel reformer; (S05) computing power follow-up working costs according to required power, the heat quantity generated from the fuel cell, fuel cell working costs from the heat quantity generated from the fuel reformer, fuel reformer working costs, cooling device working costs, and auxiliary boiler working costs; (S06) computing heat follow-up working costs according to the required power, fuel cell working costs from the power generated from the fuel cell, and system power supply costs; and (S07) controlling the fuel cell system with one control of power follow-up control or heat follow-up control by comparing the power follow-up working costs with the heat follow-up working cost. |
