NOVELTY - The method involves introducing anode fuel stream comprising reformable fuel into an anode inlet of an anode of a molten carbonate fuel cell. Cathode inlet stream comprising Carbon dioxide and oxygen, is introduced into a cathode inlet of a cathode of the molten carbonate fuel cell. The molten carbonate fuel cell is operated to generate electricity at a thermal ratio of about 1.3 or less. Anode exhaust is generated from an anode outlet of the molten carbonate fuel cell. Hydrogen-containing stream and syngas-containing stream are separated from the anode exhaust.    USE - Method for producing electricity and hydrogen or syngas used in a refinery as fuel for a boiler, furnace and a fired heater, and used as a feed for an electric power generator i.e. combustion-powered coal-fired or natural gas-fired turbine, using a molten carbonate fuel cell.    ADVANTAGE - The method enables passing excess of reformable fuel into the anode of the fuel cell to increase chemical energy output of the fuel cell instead of selecting operating conditions of the fuel cell to improve or maximize electrical efficiency of the fuel cell. The method enables operating the fuel cell with increased production of syngas, while reducing or minimizing amount of carbon dioxide exiting the fuel cell in the cathode exhaust stream. The method enables reducing amount of temperature differential across the fuel cell, thus allowing the fuel cell to operate under operating condition with increased amount of waste heat. The method enables controlling amount of fuel delivered to anode stages and amount of carbon dioxide delivered to cathode stages so as to improve performance of a fuel cell array. The method enables designing the fuel cell such that additional hydrogen and methane in the anode corresponding to the cathode stages can offset loss of voltage and current caused by the reduced carbon dioxide concentration, thus increasing voltage and net power produced by the fuel cell. The method enables easily and efficiently transporting fuel stream over long distances at low cost and effectively distributing over wide area. The method enables improving capture of carbon dioxide from the combustion-powered generator, while reducing or minimizing number of fuels cells required for capturing the carbon dioxide.    DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a structure illustrating operation of a molten carbonate fuel cell.
