Fuel cell system with recycle stream

摘要: A high-temperature integrated fuel cell system with high overall thermal efficiency is achieved by utilizing waste heat as the source of energy for fuel-reforming process. hydrocarbon mixed a recycle stream containing water vapor and mixture introduced into anode chamber molten carbonate cell. Within suitable catalyst which, addition heat, produces hydrogen-rich stream. Hydrogen reacts electrochemically at anode. The effluent essentially contains hydrogen, carbon dioxide, steam. Carbon dioxide portion removed from transferred to process air supply since relatively concentration desirable cathode in system. remaining moist recycled be fresh fuel.
