Transient response characteristics of electric power supply of small-scale fuel-cell co-generation systems constituted from a reformer, a fuel cell stack, an inverter, inter connection device system with a changeover switch, and auxiliary heat sources were investigated. Furthermore, numerical analyses of the relation of settling time, time constant of reformer and fuel cell, setting values of parameter in PI control were carried out. By changing PI control parameters according to the load of reforming, it turns out that setting time is shortened. Moreover, operating cost of the system was estimated using electric power demand and heat power demand pattern of the average individual houses in Sapporo-city and Tokyo. Consequently, annual balance of payment by installing heat pump systems with COP=3.0 into the fuel cell system serves as favorable balance in Tokyo, and become passive balance of about zero or a some in Sapporo-city.
