The operational planning of the energy network of the small fuel cell which connected each system of hydrogen, oxygen, waste heat, and electric power with piping or the electric wire is considered. Arbitrary fuel cells can be power-generation-operated or water-electrolysis-operated at arbitrary sampling time. When the fuel cell which carries out power generation operation is in the situation of partial load, water electrolysis operation is performed by other fuel cells. Consequently, the driving point of the fuel cell to generate operating is shifted to a high efficient area, and it is predicted that the whole system efficiency goes up. The hydrogen and oxygen which were generated by water electrolysis operation of fuel cells are stored in each cyinder through the network. And the hydrogen and oxygen of each cylinder shift time and are consumed by power generation operation of fuel cells. The method of the operational planning analysis was considered installing such a fuel cell network system into five residential houses of the Sapporo city. From the results of analysis, the effect of the water electrolysis operation system of fuel cells is concentrated on summer of low thermoelectric ratio. Therefore, when introducing this system into the area where a thermoelectric ratio is smaller than Sapporo city, the effect of energy saving is more large. From the developed analysis method, the maximum of the hydrogen quantity to be stored is 1.25kg, and the maximum quantity of thermal storage is estimated to be 55MJ.
