A solid-oxide fuel cell system wherein a reformate combustor is disposed in the reformate flow path between a hydrocarbon reformer and a fuel cell stack. At system start-up, reformate is partially burned within the combustor by admitting combustion air, and the partially-burned reformate is passed through the anode chambers of the stack to warm the anodes. In addition, reformate is passed through a cathode-air heat exchanger to warm combustion air entering the cathode chambers of the stack. The combustor may continue to be supplied with a low level of air during steady-state operation of the SOFC, thereby providing a moist environment within the anode chambers to prevent coking of the anodes and providing additional heat to the reformate. The combustor decouples the reformer from the stack thermodynamically, permitting the reformer and the stack each to run in its own optimal temperature range.

What is claimed is: 1. A solid oxide fuel cell system, comprising: a) a fuel cell stack including cathodes and anodes; b) a hydrocarbon reformer for providing reformate to said anodes; c) a combustor operationally disposed between said reformer and said stack for controllably adding a volume of air to said reformate to partially combust said reformate to provide moisture and heat to said anodes; and d) a heat exchanger operationally disposed between said combustor and said stack such that said partially-combusted reformate may be passed through a first side of said exchanger and cathode intake air may be passed through a second side of said exchanger to heat said cathode intake air. 2. A fuel cell system in accordance with claim 1 wherein said volume of air is selected to permit said reformer to be operated in a temperature range between about 700° C. and about 950° C., and to permit said stack to be operated in a temperature range between about 800° C. and about 1000° C. 3. A method for operating a fuel cell system including a hydrocarbon reformer operated in a first temperature range for providing reformate and a fuel cell stack operating in a second and independent temperature range for generating electricity from the reformate, the fuel cell stack including anodes and cathodes, the method comprising the steps of: a) providing a reformate combustor between said reformer and said stack; b) providing a heat exchanger between said combustor and said stack, said heat exchanger having a first side and a second side; c) operating said reformer at a selected fuel/air ratio to generate said reformate in said first temperature range; d) passing said reformate into said combustor; e) admitting air into said combustor at a controlled flowrate to cause heating of said reformate by at least partial combustion thereof; f) passing said at least partially-combusted reformate through said first side of said heat exchanger and passing cathode intake air through said second side of said heat exchanger to heat said cathode intake air; and g) passing said at least partially-combusted reformate into said fuel cell stack, wherein said combustor air flowrate is selected such that said fuel cell stack is caused to operate within said second temperature range. 4. A method in accordance with claim 3 wherein said first temperature range is between about 700° C. and about 950° C. and wherein said second temperature range is between about 800° C. and about 1000° C. 5. A solid oxide fuel cell system, comprising: a) a fuel cell stack including cathodes and anodes; b) a hydrocarbon reformer for providing reformate to said anodes; c) a partial oxidation reactor disposed between said reformer and said stack to partially oxidize said reformate to provide moisture and heat to said anodes; and d) a heat exchanger operationally disposed between said partial oxidation reactor and said stack such that said partially-oxidized reformate may be passed through a first side of said exchanger and cathode intake air may be passed through a second side of said exchanger to heat said cathode intake air. 6. A solid oxide fuel cell system, comprising: a) a fuel cell stack including cathodes and anodes; b) a hydrocarbon reformer for providing reformate to said anodes; c) a first combustor operationally disposed upstream of said reformer for controllably combusting fuel to produce heat, wherein said heat is conveyed to said reformer until said reformer reaches a threshold reforming temperature; d) a second combustor operationally disposed between said reformer and said stack for controllably adding a volume of air to said reformate to partially combust said reformate to provide moisture and heat to said anodes; and e) a heat exchanger operationally disposed between said second combustor and said stack such that said partially-combusted reformate may be passed through a first side of said exchanger and cathode intake air may be passed through a second side of said exchanger to heat said cathode intake air. 7. A fuel cell system in accordance with claim 6 wherein said first combustor is integral with said reformer. 8. A fuel cell system in accordance with claim 6 further comprising a vaporizer disposed upstream of said first combustor, wherein said fuel is mixed with air to form a fuel/air mixture, and wherein said fuel/air mixture is vaporized in said vaporizer prior to being combusted by said first combustor. 9. A fuel cell system in accordance with claim 8 wherein said first combustor and said vaporizer are integral with said reformer. 10. A fuel cell system in accordance with claim 6 wherein said threshold reforming temperature is about 550° C. 11. A method in accordance with claim 3 further comprising the steps of: providing a source of fuel to said reformer; providing a source of air to said reformer that is separate from said source of fuel, wherein said source of air and said source of fuel are mixed to form said selected fuel/air ratio.
