FUEL CELL SYSTEM, FUEL CELL SYSTEM CONTROL METHOD, AND COLLECTIVE APARTMENT HOUSE WITH IMPROVED SYSTEM-WIDE ENERGY EFFICIENCY

摘要

PPROBLEM TO BE SOLVED: To provide a fuel cell system with system-wide energy efficiency improved. PSOLUTION: The system is provided with a plurality of fuel cells each provided in the vicinity of heat loads and power loads dispersedly existing, a power network for sending power generated by a fuel cell to a power load in the vicinity of another fuel cell, and a control part for activating a fuel cell in the vicinity of a heat load with a large demand with a larger output, supplying the power to the heat load with the use of the power network from the fuel cell with excess power, and when power consumption of the power load is fluctuated, accelerating response speed of power by responding to the fluctuations with the plurality of fuel cells. The control part, if the consumption power of the power load fluctuates more quickly, accelerates response speed of the power by changing outputs of more fuel cells in comparison with the case in which the consumption power fluctuates more moderately.
