It is something. In the figure, 1 is a fuel cell main body, 2 is a humidifier, 3 is a cooling water tank, 4 is a cooling water circulation pump, and 5 is a heat recovery device for extracting heat to the outside.
In this system, the cooling water stored in the cooling water tank 3 is sent to the cooling mechanism of the fuel cell main body 1 by the cooling water circulation pump 4 to cool the fuel cell main body 1 to a predetermined operating temperature. The cooling water that has become high temperature by absorbing the reaction heat accompanying the power generation is sent from the fuel cell body 1 to the humidifier 2 and used for humidifying the fuel gas and the oxidizing gas. A typical humidifier 2 is a humidifier of a bubbling method in which a gas is passed through hot water (cooling water) held in a humidification tank and bubbling is performed to humidify the gas (see, for example, JP-A-7-226222).
Alternatively, a humidifier using a membrane humidification method in which hot water and a gas are brought into contact with each other through a water vapor permeable membrane to humidify the gas (for example, see Japanese Unexamined Patent Publication No. 7-3)
26376) is generally used. All of these humidifiers use hot water as a heat source for humidification,
The temperature of the cooling water supplied to the humidifier decreases according to the humidification amount. The cooling water whose temperature has decreased after passing through the humidifier 2 is sent to, for example, a heat recovery device 5 having a heat exchanger incorporated therein, recovers heat energy to the outside, and is returned to the cooling water tank 3 again. It is. As described above, in this type of fuel cell power generation device, electric energy is obtained by the fuel cell main body 1 and heat energy is recovered by the heat recovery device 5 incorporated in the refrigerant circulation system, so that cogeneration is performed. The power generators disclosed in the above-mentioned JP-A-7-226222 and JP-A-7-326376 are configured as a system that does not include the cooling water tank 3.

いう問題点がある。As described above, in this type of conventional polymer electrolyte fuel cell power generator, the high-temperature (temperature T3) refrigerant discharged from the fuel cell body 1 is introduced into the humidifier 2. Since humidification is performed, humidification can be performed with high humidification efficiency, and the humidifier 2 can be reduced in size. However, if the high-temperature (temperature T3) refrigerant discharged from the fuel cell main body 1 is introduced into the humidifier 2 and then introduced into the heat recovery device 5, the humidification is applied to the heat recovery device 5. Since the refrigerant whose temperature has dropped to the temperature T2 is introduced with the humidifying operation in the vessel 2, it is difficult to increase the heat recovery efficiency in the heat recovery device 5, and it is difficult to increase the heat energy to the outside. There is a problem that collection cannot always be performed sufficiently.

A main body, a humidifier for humidifying the fuel gas and the oxidizing gas,
In a polymer electrolyte fuel cell power plant equipped with a heat recovery device that recovers the reaction heat generated in the fuel cell body due to the electrochemical reaction for external use, the reaction heat is absorbed and discharged from the fuel cell body The refrigerant circulation system of the fuel cell main body is configured so that the refrigerant thus introduced is introduced into the humidifier via the heat recovery device and then supplied again to the fuel cell main body.

The refrigerant circulation system of the fuel cell main body is configured so that it flows in series or parallel to the humidifier and is then supplied to the fuel cell main body again. Here, the “humidifier” may be a humidifier separately provided outside the fuel cell main body or a humidifier (humidifying unit) formed integrally with the fuel cell main body.

補われるレベルにある。According to the above (1), since the high-temperature refrigerant discharged from the fuel cell main body is directly introduced into the heat recovery device, the heat recovery in the heat recovery device is performed at a higher temperature than in the past. And the heat utilization efficiency increases. Therefore, the overall energy efficiency of the combined heat and power generation device is increased. In addition, with such a configuration, the refrigerant after passing through the heat recovery device is introduced into the humidifier, so that the humidification efficiency is reduced and the power generation efficiency is reduced. Is small and sufficiently compensated by the structural improvement of the fuel cell body which has been actively promoted in recent years.
