The transient response characteristics of the power supply of a small-scale fuel-cell co-generation system, constituted from a reformer, a fuel cell stack, an inverter, an interconnection device system with a changeover switch, and auxiliary heat sources were investigated. Furthermore, the relation among the settling time, time constant of the reformer and the fuel cell, and the setting values of the parameter in PI control was analyzed. By changing the PI control parameters according to the reforming load, the setting time is shortened. Moreover, the operating cost of the system was estimated, with reference to the power demand and heat demand pattern of individual houses in Sapporo and Tokyo. Consequently, the annual balance of payments achieved by installing a heat pump system with COP=3.0 into the fuel cell system shows a favorable balance in Tokyo, and a passive balance of about zero in Sapporo respectively.
