PURPOSE:To reduce the driving power of a compressor device by operating an absorption type refrigerator using the exhaust gas heat energy of an expansion machine device and reducing the air that is under the compression process of the compressor device below atmospheric temperature. CONSTITUTION:By the energy of high temperature and pressure gas b in a fuel cell power generating system, an expansion machine device 1 is driven and a compressor device 2 is operated. The compressor device compresses the atmospheric air a to the specified pressure and supplies it to the oxydizing electrode 5a of the fuel cell. In addition, an absorption type refrigerator 3 that uses the exhaust gas energy of a low pressure expansion machine 1a as the heat source is porovided and the air obtained from a low pressure compressor 2a through an intermediate cooler 4 is cooled below the atmospheric temperature by the heat exhange with the coolant within the refrigerator 3 and is absorbed in a high pressure compressor 2b. As a result, the driving power of the compressor device 2 can be reduced by cooling the air in the compression process using the absorption type refrigerator 3. |
