An integrated system utilizing a solid oxide fuel cell and at least one ion transport reactor to generate electric power and a product gas by delivering an oxygen-containing gas, typically air, to a first cathode side of the solid oxide fuel cell and delivering a gaseous fuel to a first anode side.

An integrated system utilizing a solid oxide fuel cell and at least one ion transport reactor to generate electric power and a product gas by delivering an oxygen-containing gas, typically air, to a first cathode side of the solid oxide fuel cell and delivering a gaseous fuel to a first anode side. Oxygen ions are transported through a membrane in the fuel cell to the first anode side and exothermally react with the gaseous fuel to generate electric power and heat. The heat and oxygen transport produces a higher-temperature, reduced-oxygen-content gaseous retentate stream exiting the cathode side of the solid oxide fuel cell which is delivered to a first ion transport reactor where a substantial portion of the residual oxygen is transported through an oxygen selective ion transport membrane. A product gas stream is then recovered.

[ What is claimed is:] [1.] A process for the generation of electric power and a product gas stream from a mixture of an oxygen-containing stream gas and a first gaseous fuel stream, comprising:(a) providing a solid oxide fuel cell having a first cathode side and a first anode side;(b) providing a first ion transport reactor having an oxygen-selective ion transport membrane disposed therein, said oxygen-selective ion transport membrane having a second cathode side and a second anode side;(c) contacting said oxygen-containing gas stream with said first cathode side and contacting said first gaseous fuel stream with said first anode side;(d) transporting a first oxygen portion of said oxygen-containing gas stream from said first cathode side to said first anode side;(e) reacting said first oxygen portion with said first gaseous fuel stream at said first anode side and generating a flow of electrons from said first anode side to said first cathode side;(f) recovering said flow of electrons as electric power;(g) directing a remainder of said oxygen-containing gas stream as a first retentate stream from said first cathode side to said second cathode side;(h) contacting said first retentate stream with said second cathode side and transporting a second oxygen portion from said second cathode side to said second anode side; and(i) recovering a gas stream as said product gas stream from at least one of said first cathode side, said first anode side, said second cathode side and said second anode side.
