HIGH EFFICIENCY FUEL CELL SYSTEM SUPPRESSING VARIATION IN POWER CONSUMPTION, METHOD FOR CONTROLLING FUEL CELL SYSTEM AND BUILDING STRUCTURE

摘要

A fuel cell system in which variation in power consumption of the entire system can be suppressed and energy loss can be reduced. The fuel cell system comprises a fuel cell, a power load which operates using the power generated by the fuel cell, a demand control section for transmitting power 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 a notice of permitting increase in power consumption is received from the fuel cell control section. The fuel cell control section transmits a permission notice to the load control section of one power load such that power consumption of this power load increases at the lowering timing of power consumption of another power load.
