PURPOSE:To enhance the energy efficiency of a fuel cell as a whole by providing a decompressing means and a pressurizing means in reasonable arrangement, wherein the decompressing means is required for fuel gas supply to the fuel electrode side and the pressurizing means is required for supplying oxygen containing gas to the oxygen electrode side. CONSTITUTION:A fuel modifier 10 and a transformer 11 are installed in a modified fuel gas supply path 9, and also a decompressing means 12 is installed which decompresses the modified fuel gas from the modifier 10 and transformer 11 down to a specified level and supplies to the fuel electrode 1a side of a power generation part 1. On the other hand, a pressurizing means 14 for pressurizing and supplying air to the air electrode 1b side is installed in an air supply path 4, which is connected with the air electrode (oxygen electrode) 1b side of the power generation part 1. That is, the pressure energy possessed by the modified fuel gas is consumed for power generation at a turbine part 15a, and thereby supplying the fuel electrode 1a is performed. Pressurized supplying of the air electrode 1b side is made, on the other hand, with the modified fuel gas decompressed and the air pressurized by a blower part 15b due to power generation by the turbine part 15a. |
