摘要： PURPOSE:To provide a water recovery processing device simple in small size at a low cost by providing a condensation separator, comprising a condensing heat exchanger, mist separator, carbon dioxide take out port, wire mesh and an air blow nozzle, in an exhaust gas flow path of a reformer. CONSTITUTION:Exhaust gas 10a generated in a combustion side of a reformer 10, when advanced into a condensation separator 33, is cooled by a condensing heat exchange part 35 in the upper part of a vessel main unit 34, to store water as the condensed water 23 in a bottom part. The rest of carbon dioxide 24, after a mist is separated in a mist separator 36 by compressed air 7 from an air blow nozzle 39, is supplied with the air 7 to a cathode electrode 5 of a fuel cell 1 through a low temperature blower 25 from a carbon dioxide take out port 37. The water 23, accumulated in the bottom part of the main unit 34, is processed by alkaline water in a water purifying device 26, thereafter guided to a boiler 27 and presented to serve as generating reforming steam. Since water condensation and steam separation are performed by the single separator 33, a device can be simply miniaturized.

摘要： PURPOSE:To prevent the generation of high differential pressure between a reforming chamber in a plate type reformer and a combustion chamber, and between the inside and the outside of there former. CONSTITUTION:Pressure of a cathode outlet gas exhausted from a cathode 2 of a fuel cell FC is kept constant. A line 12 branched from an air supply line 4 which supplies air A to the cathode 2 is connected to a combustion chamber 9b of a plate type reformer 9. An anode outlet gas exhausted from an anode 3 of the fuel cell FC is introduced into the combustion chamber 9b, and the pressure of the anode outlet gas is equalized with the pressure of air A in the combustion chamber 9b. A reforming chamber 9a from which gas is supplied to the anode 3 becomes almost the same pressure as the combustion chamber 9b, and high differential pressure is not produced. Air introduced into the combustion chamber 9b is discharged into a pressure container 24, to keep the combustion chamber to almost the same pressure as the pressure container 24, and the generation of high differential pressure between the inside and the outside of the reformer is prevented.

摘要： PURPOSE:To lower the operation temperature of a cathode recycle blower which pressure-increases and recycles a portion of the cathode outlet gas having a high temperature, in order to increase the temperature of the oxidizing gas supplied to the inlet side of a cathode. CONSTITUTION:A portion of the cathode outlet gas which is discharged from the outlet side of the cathode 2 of a molten carbonate type fuel battery 1 is allowed to flow in a recycle line 17, and pressure-increased by a cathode recycle blower 18, and directly returned to the inlet side of the cathode 2. The oxidizing gas supplied to the inlet side of the cathode 2 is allowed to join with the recycle line 17 on the suction side of the cathode recycle blower 18. The cathode outlet gas having a high temperature and the oxidizing gas having a low temperature are mixed, and the gas having the lowered temperature is pressure-increased by the cathode recycle blower 18, and the operation temperature of the blower 18 is softened.

摘要： PURPOSE:To extend the lives of a reformer itself and a reforming catalyst, perform most of reforming in a first reformer situated on the upper stream side to make a second reforming chamber on the lower stream side small, so that the reforming catalyst can be easily exchanged even if it is poisoned by carbonate. CONSTITUTION:A plurality of molten carbonate fuel cells I, II are provided. Between the fuel cell I on the upper stream side and the fuel cell II on the lower stream side, a second reforming chamber 29 using the sensible heat of an anode outlet gas as a heat source is disposed. They are connected in series so that the gas reformed by a first reformer 4 situated on the upper stream side is sent in the order of the anode 3 of the fuel cell I, the second reforming chamber, and the anode 3 of the fuel cell II. The anode outlet gas and cathode outlet gas of the fuel cell II on the lower stream side are partly guided to a combustor 14. The combustion heat of the combustor 14 is used as the heating source of the first reformer 4.

摘要： PURPOSE:To lower the cost of an electricity generating apparatus by using a steam generator for taking out and reforming in double and to recover the electric power by driving a steam turbine with high pressure steam and to use the recovered power to drive the apparatus. CONSTITUTION:A high temperature gas is led to pass a steam superheating heater 20 and a steam generator 21. A part of high pressure steam generated by the sensible heat of the high temperature is supplied to a steam turbine 30. The electric power recovered by the driving of the steam turbine 30 is used to drive a high temperature cathode recycle blower 18. The steam coming out from the steam turbine 30 is supplied to a natural gas supplying line 6 to be used for reforming. Consequently, a steam generator for reforming is made unnecessary. Also, neither driving motor for the cathode recycle blower 18 nor electric power for driving motor is needed and thus necessary motive force in the apparatus is lessened.

摘要： PURPOSE:To facilitate change operation by eliminating a differential pressure adjusting valve for controlling a differential pressure between a fuel call vessel and a fuel cell. CONSTITUTION:A fuel cell I is stored in a vessel 4. After an unconverted component in anode outlet gas in the fuel cell I is burned by oxygen in cathode outlet gas, the gas is cooled through a heat exchanger to decrease a temperature, boosted by a low temperature recycle blower 31 to join with air A and supplied to a cathode 2. Gas of low temperature, boosted by this blower 31, is partly supplied into the vessel 4 of the fuel cell I so as to balance a pressure of the vessel 4 with a pressure of the cathode 2.

摘要： PURPOSE:To shorten the distance of piping from a cathode blower to each of numerous reformers and each of numerous fuel cells by separating piping on the inlet and outlet sides of a cathode blower into two parts, and connecting the two parts to the reformer and fuel cell of each cell module, respectively. CONSTITUTION:Gas discharged from the combustion chamber of the reformer 4 of each of numerous cell modules A is centralized into one cathode blower 17 through piping 14a on the inlet side of the cathode blower 17 and is supplied from the cathode blower 17 to the cathode of the fuel cell I of each of the numerous cell modules A through piping 14b on the outlet side of the blower. In this case, the piping 14a and 14b connecting each reformer 4 and each fuel cell 1 to one cathode blower 17 can be relatively shortened because the cathode blower 17 is located at the center of the numerous cell modules A, and in addition, a symmetrical piping layout can be offered so gas is distributed well from each reformer 4 to each fuel cell I.
