<P>PROBLEM TO BE SOLVED: To obtain a fuel cell power generation system of a high heat recovery temperature, which is a type having a coolant tank to store a cooling medium to cool a fuel cell stack, and of utilizing heat of this cooling tank as cogeneration by recovering it. <P>SOLUTION: This is provided with a reflux port, in which the end part of a downstream of a coolant piping is connected in the coolant tank in order to store the coolant to cool the fuel cell stack and with a heat exchanger tube in which a heat recovery fluid is circulated in the vicinity, and is provided with a coolant stream control mechanism in the coolant tank so that a stream of the heat recovery fluid flowing in this heat exchanger tube, and a stream of the coolant flowing in the vicinity of the reflux port in the coolant tank will make a mutually opposed flow. <P>COPYRIGHT: (C)2007,JPO&INPIT |
