AIR-CONDITIONING SYSTEM HAVING FUEL CELL, AIR-CONDITIONING METHOD USING FUEL CELL, AND FUEL CELL VEHICLE HAVING AIR-CONDITIONING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a technology capable of enhancing energy utilizing efficiency in an air-conditioning system having a fuel cell, and suppressing the stability of temperature control.

SOLUTION: A fuel cell power generation system 100 executes the intermittent operation of alternatively repeating a first operational state that a secondary cell 160 is charged while power generated by a fuel cell 110 is output to the outside of the system in the case of a low load, and a second operational state that the operation of the fuel cell 110 is stopped, and power from a secondary cell 160 is output to the outside of the system. An in-vehicle air-conditioning system 200 utilizes the output power from the fuel cell power generation system 100 in a heating mode, and also utilizes the waste heat of the fuel cell 110 via a refrigerant of the fuel cell. Furthermore, when the fuel cell power generation system 100 is in the first operational state, the drive of electric heaters 262, 263 is stopped, and when the fuel cell power generation system is in the second operational state, the refrigerant for the fuel cell is heated by the electric heaters 262, 263.
