A method of using a SOFC system for producing a refined carbon dioxide product, electrical power and a compressed hydrogen product the method of using a SOFC system comprising the steps of: introducing a hydrocarbon fuel to the SOFC system; introducing steam to the SOFC system; and operating the SOFC system such that an anode exhaust recycle forms and passes into a pre-reformer such that a steam-to-carbon molar ratio in the pre-reformer is in a range of from 3:1 to 4:1; oxygen passes into a reformer combustion chamber in excess of a stoichiometric amount required to fully combust all of the hydrocarbons and hydrogen present in the reformer combustion chamber; the refined carbon dioxide product, electrical power and the compressed hydrogen product are produced; and greater than 90% of the total carbon dioxide produced within the SOFC system is converted into the refined carbon dioxide product; where the SOFC system includes a hydrodesulfurization system (4,10) that fluidly couples to a hydrogen compression and storage system and is operable to receive a hydrocarbon fuel; a steam reformer having a catalytic reactor tubes and the reformer combustion chamber, where the catalytic reactor tubes couple to the hydrodesulfurization system and are operable to receive steam and where the reformer combustion chamber thermally couples to the catalytic reactor tubes and fluidly couples to both an outlet of an anode side of a solid oxide fuel cell and an oxygen generator system (40,78) and is operable to receive a hydrocarbon fuel; a water-gas shift reactor system that fluidly couples to the reformer catalytic reactor tubes and is operable to convert carbon monoxide into carbon dioxide and hydrogen; a hydrogen purification system that fluidly couples to the catalytic reactor tubes and is operable to produce a purified hydrogen gas; a hydrogen compression and storage system that fluidly couples to the hydrogen purification system and is operable to produce a compressed hydrogen product; the pre-reformer that fluidly couples to the outlet of the anode side of the solid oxide fuel cell and is operable to receive the hydrocarbon fuel and to produce a pre-reformer syngas product; the solid oxide fuel cell that is operable to produce electrical power and has the anode side, the anode side having an inlet that fluidly couples to both the pre-reformer and the hydrogen purification system and is operable to produce the anode exhaust gas; the oxygen generation system that is operable to produce oxygen; and a CO2 purification and liquidification system that fluidly couples to the reformer combustion chamber and is operable to produce a refined carbon dioxide product. introducing a hydrocarbon fuel to the SOFC system; introducing steam to the SOFC system; and operating the SOFC system such that an anode exhaust recycle forms and passes into a pre-reformer such that a steam-to-carbon molar ratio in the pre-reformer is in a range of from 3:1 to 4:1; oxygen passes into a reformer combustion chamber in excess of a stoichiometric amount required to fully combust all of the hydrocarbons and hydrogen present in the reformer combustion chamber; the refined carbon dioxide product, electrical power and the compressed hydrogen product are produced; and greater than 90% of the total carbon dioxide produced within the SOFC system is converted into the refined carbon dioxide product;
