FUEL CELL SYSTEM, FUEL CELL SYSTEM CONTROL METHOD, AND BUILDING that suppresses peak power consumption below maximum generated power

摘要

A fuel cell system in which the peak of power consumption can be prevented appropriately from exceeding the maximum power generation of the fuel cell. The fuel cell system comprises a fuel cell, a power load which operates using electric power, a demand control section for transmitting demand information in advance when it is necessary to increase the power consumption of the power load, a fuel cell control section for transmitting a notice of permitting increase in power consumption on condition that the fuel cell can supply more power to the power load upon receiving the demand information from the demand control section, and a load control section for increasing power consumption of the power load on condition that the notice of permission is received from the fuel cell control section. The fuel cell control section instructs the load control section to lower power consumption when power consumption of the power load is required to be lowered in order to maintain the total power consumption at a low level. Upon receiving the order to lower power consumption from fuel cell control section, the load control section lowers power consumption.
