PURPOSE:To effectively recover heat to be discharged from a fuel cell to a maximum limit and to utilize it in a fuel cell refrigerator integral system. CONSTITUTION:A double effect absorption type refrigerating cycle is composed of a refrigerant regeneration tube 4, a low temperature regenerator 16, a condenser 17, an absorber 18 and an evaporator 19, and cold is obtained by the evaporator 19. Here, the tube 4 is disposed in a fuel cell 1. Heat from the cell 1 by generation is recovered to be also used for cooling, directly applied to dilute absorption solution in a double effect refrigerating cycle without intermediary of intermediate medium, regenerated water refrigerant vapor is separated by a steam separator B11, and supplied to the regenerator 16 as a drive heat source. Thus, a decrease in energy and heat loss upon heat exchange and heat transfer are prevented when the intermediate medium is used, suppressed to minimum. Thus, waste heat from the cell 1 is recovered to a maximum limit and utilized for generating cold. |
