A fuel cell power generation system uses natural gas as a raw material, generates hydrogen-rich gas in a fuel reformer, uses oxygen in the air as an oxidant, causes a reaction in a battery, and uses the resulting DC output with an inverter. It is exchanged for exchange.
At that time, the air is pressurized by a compressor, and then the flow control system 1,
2 and 3, the fuel is humidified by steam, heated through a heat exchanger 4, and adjusted to flow rate, temperature, and humidity appropriate for the reaction, and then enters the fuel cell main body 6. At this time, the separated contained water is discharged from the drain 5.

After the reaction, the air leaving the air electrode has a high temperature and high humidity, and is cooled by the heat exchanger 10 and released into the atmosphere. At that time, the separated contained moisture is discharged from the drain 11.

構成されたものである。 Hereinafter, one embodiment of the present invention will be described based on FIG. 2. In the figure, 1 is a flow sensor, 2 is a flow controller, 3 is a flow control valve, 6 is a fuel cell main body,
7 is a pressure sensor, 8 is a pressure regulator, 9 is a pressure regulating valve, and 12 is a temperature/humidity exchanger. As the temperature/humidity exchanger 12, there is one described as a "fixed type total heat exchanger" for air conditioning on page 157 of "Air Conditioning Standard Text" published by Ohmsha Co., Ltd. (February 1981). As shown in Figure 3, this is a partition plate 1 made of special asbestos paper that has heat and moisture permeability.
3 and a spacer plate 14 made of special kraft paper, the air supply and exhaust air are separated from each other and passed through.

極に入る前に外部から予め加湿されている。 Next, the operation will be explained. The flow rate of the supplied air is controlled by flow rate control systems 1, 2, and 3. Thereafter, through the temperature/humidity exchanger 12, heat and humidity are exchanged with air that has become humid and high temperature due to reactions within the cell, and enters the air electrode of the fuel cell main body 6. Note that the pressure is controlled to a predetermined pressure by pressure control systems 7, 8, and 9 on the outlet side of the fuel cell main body 6. After reacting with the fuel, the air passes through the temperature/humidity exchanger 12 again, undergoes heat and humidity exchange with low-temperature, low-humidity air, and is exhausted. Note that when the battery is started, the supplied air is humidified from the outside before entering the air electrode.
