PURPOSE:To recycle the fuel electrode gas at the lower stream area of the passage in a simple method, by furnishing a throttle at the entrance of the fuel gas passage to speed up the gas flow, and absorbing the fuel electrode gas in the lower stream of the passage by the negative pressure effect. CONSTITUTION:A steam reforming catalyst 5 is filled at the fuel gas passage 4 contacting to fuel electrode 2, and at a nozzle 23 at the entrance of the fuel gas passage, a throttle 24 is arranged, to compose an inside reform type molten carbonate fuel cell. A hydrocarbon gas 11 is fed from a maniford 19 through the nozzle 23 to the fuel gas passage 4, and a generation is carried out under the presence of the reforming catalyst 5 by the cell reaction. At the same time, the flow speed is accelerated by the throttle 24 of the nozzle 23 to produce a negative pressure, and the fuel electrode gas 16 at the lower stream of the passage is absorbed thereby through the flow passages 26 and 25, and mixed at the throttle 24 to recycle. Therefore, the fuel gas can be reused readily with no blower, preheater and the like. |
