    • PURPOSE: A fuel cell system integrated with heat pump is provided to counteract fluctuation of cooling or heating load without causing fluctuation of electric load. CONSTITUTION: A fuel cell system integrated with heat pump comprises a fuel cell part, a heat pump part, and a variable area type turbocharger (301). The fuel cell part generates electricity through electrochemical reaction and produces high temperature cathode off gas. The heat pump part includes an evaporator (302), a compressor (301B), a vaporizer with an expansion valve (304). The variable area type turbocharger connects the fuel cell part with the heat pump part. The variable area type turbocharger conveys the cathode off gas to a heat exchanger of the fuel cell part, generating driving force with the cathode off gas, and controls with the driving force the pressure and velocity of refrigerant circulating inside the heat pump part.

    • PURPOSE: A catalytic combustion apparatus with complete uniform flow for a large capacity internal-reforming MCFC(Molten Carbonate Fuel Cell) is provided to maintain uniform pressure distribution of mixed gas and uniform gas flow in branch pipes. CONSTITUTION: A catalytic combustion apparatus with complete uniform flow for a large capacity internal-reforming MCFC comprises a gas mixing part(1), a uniform flow guide section, a complete catalytic combustion section(3), and an exhaust gas supply section(4). The gas mixing part separately supplies and mixes cathode by-product gas(11) and anode air(12) which are produced according to the reforming reaction of MCFC stack outside an MCFC stack vessel(6). The uniform flow guide section has a perforated or branched structure in order to maintain uniform flow distribution of the mixed gas supplied to the MCFC stack vessel. The complete catalytic combustion section completely burns the mixed gas through multi-stage catalysts(31,32). The exhaust gas supply section supplies high-temperature heat and exhaust gas to the MCFC stack vessel.
