PURPOSE:To provide an optimum system in view of a demand by combining a thermoelectric ratio judging device capable of detecting a change in thermoelectric ratio over a wide range, a fuel generating plant and a exhaust heat recovery system. CONSTITUTION:In a battery cooling system, a heat exchanger 4b for recovering exhaust heat is interposed between another heat exchanger 4a for discharging exhaust heat and a circulating pump 3, and is connected onto a demand side 7, thus constituting an exhaust heat recovery system 8. A heat ratio judging device calculates a ratio of a heat load requiring value on the demand side to a power transmission load requiring value thereon to set a target generating load and a target load in addition to an exhaust heat discharging command, and sends them to the heat exhaust recovery system 8. Flow rates, temperatures and the like of the heat exchanger 4a connected to a cooling tower 5 and the heat exchanger 4b of the recovery system 8 are controlled on the basis of the command. Consequently, only the load required for the demand is supplied from the exhaust heat of a fuel cell generating plant. Moreover, extra exhaust heat is discharged to outside air so that a stable heat supplying generating system can be obtained and a heat load and an electric load which are widely changed can be supplied. |
