ELECTRIC POWER PRODUCING SYSTEM USING MOLTEN CARBONATE TYPE FUEL CELL

摘要

ELECTRIC POWER PRODUCING SYSTEM USING MOLTEN CARBONATE TYPE FUEL CELL An electric power producing system using a molten carbonate type fuel cell, comprises a fuel cell whose anode chamber Is provided with hydrogen gas and whose cathode chamber is provided with air and carbon dioxide and a reformer including a reforming chamber for reforming fuel gas into anode gas and a combustion chamber for maintaining reforming chamber temperature. In the reformer, fuel gas and steam are fed into the reforming chamber, gases discharged from the anode chamber are introduced into the combustion chamber and non-reacted gases in the anode exhaust gas are burned with air, and heat produced upon the combustion is used to heat the reforming chamber. Hydrogen-rich gas made in the reforming chamber Is fed into the anode chamber, air is introduced into the cathode chamber, the cathode exhaust gas is partially fed into the combustion chamber whereas the remainder Is discharged from the system, and combustion gas from the combustion chamber is separated from water and then recirculated into the cathode chamber. The anode exhaust gas and cathode exhaust gas are directly introduced into the combustion chamber so that the anode and cathode chambers are made substantially equal to each other in pressure.
