PURPOSE: A combined power generation system connected to a thermal power generation system and a molt carbonate fuel cell power generation system is provided to store carbon dioxide which does not supply to an MCFC in an additional storage device. CONSTITUTION: A combined power generation system comprises a thermal power generation system and a molt carbonate fuel cell power generation system. A carbon dioxide collector(14) of the thermal power generation system collects CO2 from exhaust gas discharged from a thermal power generation plant(10). The MCFC power generation system comprises a fuel cell stack(20) and supplies hydrocarbon from a hydrocarbon generator(31) to a fuel electrode of the fuel cell stack.

PURPOSE: A multi fluid mixing ejector and a fuel cell system applied with the same, which reduces the costs and space limitation by mixing different kind of fluid are provided to freely control the flow rate and pressure of a fluid drive part and an intake part. CONSTITUTION: A multi fluid mixing ejector comprises a fluid driving part(120), a first suction part(150), a second suction part(160), a neck part(190) and a diffuser(195). The fluid driving part makes Q1 driver fluid flow between an outer pipe(140) and inner pipe(130) of a driving part. The first suction part inhales Q2 driver fluid between the inner pipes of a ring-shaped driving part. The neck part is formed in cyclic type between a shaft(180) and an external housing(170). The neck part mixes the Q1, Q2 and Q3, drive fluid which flow from the outlets of intake part of fluid driving part. The diffuser is extended with the neck part and improves the pressure of a driver fluid mixed in a neck part.

PURPOSE: A molten carbonate fuel cell system connected with a carbonate refrigerant-generator and a heat pump is provided to efficiently utilize carbon dioxide with low ozone depletion index and global warming potential without combustibility and toxicity. CONSTITUTION: A molten carbonate fuel cell system connected with a carbonate refrigerant-generator and a heat pump comprises: a fuel cell(200) consisting of a fuel electrode(210), an air electrode(220), and electrolyte(230); a combustor(300) which is connected to the fuel electrode and generates the heat by burning exhaust gas containing carbon dioxide by the air; a water separator(400) which is connected to the combustor and separates water from wasted gas including the carbon dioxide; and a carbon dioxide separator which is connected to the water separator and separates carbon dioxide from waste gas.
Abstract:
PURPOSE: A separator for high-temperature fuel cell is provided to improve stack function and efficiency of fuel cell system. CONSTITUTION: A separator for high temperature fuel cell comprises: a fuel electrode(10) as a electrode plate and air electrode(80); a pair of mask plates(20,70) which seals between a pair of electrodes; a current collectors(30,60) connecting the pair of electrodes; a corrugated plates(40,50) preventing mix fuel gas and air; and a support(90).
Abstract:
PURPOSE: An external reforming type molten carbonate fuel cell system is provided to reduce an excess of air flow for removing heat generation of a stack by using the heat in a reforming reaction and to decrease power consumption of a fuel supply apparatus. CONSTITUTION: An external reforming type molten carbonate fuel cell system comprises a reforming gas supply device(20) for supplying reforming gas; a reforming reaction device(10) for performing reforming reaction by receiving the reforming gas from the reforming gas supply device; a fuel electrode/reforming catalyst for performing reforming reaction by receiving the reformed gas from the reforming reaction device; and a heat exchanger-I(40) for heating the fuel gas provided to the fuel electrode/reforming catalyst.
