The installation to the individual house of the PEM fuel cell cogeneration with heat pump is considered. The electric power and the heat power output characteristics of the system differ from each other with the control variables of system-control devices. Then, the operation actions of the system were analyzed using the electric power load pattern accompanied by short time random fluctuations. As a result, the transient response characteristics of the system are good by changing the control variables of controllers with the values of electric power load and heat power load. Furthermore, generation efficiency falls, so that electric power load and load fluctuations become large. The electric power consumption of heat pump is influenced by the values of the exhaust heat of a fuel cell stack and a reformer. When adding the same heat load as the system, the electric power consumption of heat pump decreases, so that electric power load and load fluctuations are large. Therefore, if a PEM fuel cell system is introduced into load patterns with large fluctuations in a short time of electric power load with little heat demand, it will be predicted that the advantageousness of the system decreases.
