A novel home cogeneration system that is available to air conditioning use has been proposed, and its feasibility has been investigated theoretically. Waste heat from the PEFC is usually utilized as a hot water in micro cogeneration. But, in Japan, in order to reduce increasing power consumption for air conditioning in residential use, it is indispensable to develop a home cogeneration system that can be used for air conditioning. Therefore, a single effect absorption chiller heater was adopted as waste heat recovery equipment. The absorption chiller heater is driven by the low temperature waste heat of the PEFC and is available for air conditioning. Their performances and efficiencies were predicted quantitatively by computer simulation. Total efficiency of the system reached about 80 % when the waste heat is recovered only as a hot water. But the total efficiency decreased with an increase of waste heat use for the purpose of air conditioning.
