In this paper, we have proposed that an electric double layer capacitor storage, which has quick response in output or input of electricity but has smaller capacity than normal secondary batteries, is applied to a residential fuel cell co-generation system to shave spike-like electric power consumptions. The method is expected to enhance the utilization rate of the system and to moderate burdens for power grid connecting to such distributed generator as fuel cell.<br>A low-pass filter method was introduced for balancing between the power supply and the demand, and leveling the power input from a grid. According to the simulation by using practically measured load patterns, the appropriate storage capacity is about 500Wh for a household, the fuel cell utilization rate or the grid burden improvement is increased by around 40% in comparison with the case of the system without storage capacity. It has been clarified that, in the energy network method of over 5 households, the storage capacity can be approximately reduced down to 40% with extreme burden improvement less than 90% of the stand alone condition. Also we have verified the practical operation and the performance by using an experimental system.
