NOVELTY - The method comprises introducing a hydrocarbon fuel to a solid oxide fuel cell (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 (46), a steam-to-carbon molar ratio in the pre-reformer is 3:1-4:1, oxygen passes into a reformer combustion chamber (16) in excess of a stoichiometric amount required to fully combust the hydrocarbons and hydrogen present in the reformer combustion chamber, and the refined carbon dioxide product, electrical power and the compressed hydrogen product are produced.    USE - The method is useful for producing a refined carbon dioxide product, electrical power suitable for electrically powered vehicles and a compressed hydrogen product for hydrogen fuel cell vehicles using a SOFC system (all claimed).    ADVANTAGE - The pre-reformer converts both new and recycled streams into methane to maximize the internal reforming capacity of the SOFC thus lowering overall utility requirements and improving operational efficiency for converting fuel into electricity. The method is capable of utilizing an internal reforming process to support cooling of an interior of the SOFC thus saving energy and reducing footprint-both in energy use and size-of the system.    DETAILED DESCRIPTION - The method comprises introducing a hydrocarbon fuel to a solid oxide fuel cell (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 (46); a steam-to-carbon molar ratio in the pre-reformer is 3:1-4:1; oxygen passes into a reformer combustion chamber (16) 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. The SOFC system includes: a hydrodesulfurization system that fluidly couples to a hydrogen compression and storage system and is operable to receive a hydrocarbon fuel; a steam reformer (12) having a catalytic reactor tubes (14) and the reformer combustion chamber, where the catalytic reactor tubes couple to the hydrodesulfurization system and are operable to receive steam and the reformer combustion chamber thermally couples to the catalytic reactor tubes, fluidly couples to both an outlet of an anode side of a SOFC (34) and an oxygen generator system and is operable to receive a hydrocarbon fuel; 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 SOFC and is operable to receive the hydrocarbon fuel and to produce a pre-reformer syngas product; the SOFC that is operable to produce electrical power and includes 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 carbon dioxide purification and liquidification system that fluidly couples to the reformer combustion chamber and is operable to produce a refined carbon dioxide product. The introducing step comprises: introducing compositionally similar hydrocarbon fuel to the parts of the SOFC system operable to receive the hydrocarbon fuel; introducing a first hydrocarbon feed composition to one part of the SOFC system operable to receive hydrocarbon fuel; introducing a second hydrocarbon fuel composition to second part of the SOFC system operable to receive hydrocarbon fuel; and introducing steam such that a steam-to-carbon molar feed ratio in the catalytic reactor tubes is 2:1-4:1. The operating step comprises: passing a portion of the compressed hydrogen product from the hydrogen compression and storage system to the hydrodesulfurization system; maintaining a temperature of the catalytic reactor tubes at 775-825 degrees C and at a pressure of 8-10 bars; maintaining the steam reformer at a differential temperature of 90 degrees C between the reformer combustion chamber and the catalytic reactor tubes; producing a purified hydrogen gas having a hydrogen purity in a range of 99.50-99.99 mole%; operating the pre-reformer adiabatically; maintaining a temperature of the pre-reformer at 350-400 degrees C; producing the pre-reformer syngas product having methane in a range of 15-20% on a dry mole basis; maintaining a temperature of the anode side of the SOFC at 725-775 degrees C; producing oxygen having an oxygen purity of 95-99.99 mole% on a dry molar basis; and producing the refined carbon dioxide product having an oxygen concentration of less than about 10 parts-per-million molar. An excess of the stoichiometric amount required is 10 percent greater than the stoichiometric amount required to fully combust all of the hydrocarbons and hydrogen present in the reformer combustion chamber. The steam-to-carbon molar ratio for the catalytic reactor tubes is less than the steam-to-carbon molar ratio for the pre-reformer. The oxygen generation system of the SOFC system includes an electrolysis cell that electrically couples to the SOFC and is operable to receive water and electrical power and to produce electrolysis hydrogen and electrolysis oxygen. The hydrogen compression and storage system is fluidly coupled to the oxygen generation system. The method further comprises introducing water to the SOFC system; and operating the SOFC system such that electrical power passes to the oxygen generation system, the oxygen generation system produces both an electrolysis oxygen and an electrolysis hydrogen separately, and the electrolysis hydrogen passes to the hydrogen compression and storage system. INDEPENDENT CLAIMS are included for:    (1) SOFC system for producing a refined carbon dioxide product, electrical power suitable for electrically powered vehicles and a compressed hydrogen product for hydrogen fuel cell vehicles;    (2) a method for using an alternative fuel fueling station to fuel an alternative fuel vehicle; and    (3) an alternative fuel fueling station useful for fueling both electrical and hydrogen alternative fuel vehicles simultaneously.
