What is claimed is: 1. An apparatus, comprising: an engine; and an exhaust system for conducting exhaust emitted by the engine and including a catalytic device configured to generate a voltage and to treat emissions from the engine, the catalytic device including: a support having an interior surface and an exterior surface; a fuel cell portion including a cathode structure adjacent the exterior surface and an anode structure adjacent the interior surface; and a catalytic conversion portion disposed adjacent the fuel cell portion and configured to supply heat to the fuel cell portion. 2. The apparatus of claim 1, wherein the catalytic conversion portion comprises a three-way catalytic structure formed on at least a portion of the anode structure. 3. The apparatus of claim 1, further comprising a casing containing the support. 4. The apparatus of claim 3, wherein the support comprises an upstream end sealed to the casing via a seal that seals the exterior surface from exhaust flowing within the exhaust system. 5. The apparatus of claim 3, wherein the casing comprises an oxidant inlet configured to provide an oxidant to the cathode for consumption in the fuel cell portion. 6. The apparatus of claim 5, wherein the oxidant inlet is configured to provide air to the cathode. 7. The apparatus of claim 5, wherein the oxidant inlet is configured to provide lean exhaust to the cathode. 8. The apparatus of claim 1, wherein the fuel cell portion is a first fuel cell portion, and wherein the catalytic device further comprises a second fuel cell portion. 9. The apparatus of claim 8, wherein the catalytic device comprises a support having an interior surface and an exterior surface, and wherein the first fuel cell portion and the second fuel cell portion each includes a cathode formed on a portion of the exterior surface of the support and an anode formed on a portion of the interior surface of the support. 10. The apparatus of claim 8, wherein the catalytic device further comprises a third fuel cell portion. 11. The apparatus of claim 8, wherein the first fuel cell portion is electrically connected to the second fuel cell portion in series. 12. A catalytic device for treating emissions from an engine, the catalytic device comprising: a support structure having an exterior surface and an interior surface, wherein the support structure includes a solid electrolyte material; a layer of an anode material disposed on at least a portion of the interior surface of the support structure; a layer of a cathode material disposed on at least a portion of the exterior surface of the support structure; and a three-way catalytic layer disposed on at least a portion of the layer of the anode material and configured to supply heat to the anode material by catalyzing a heat-producing reaction. 13. The catalytic device of claim 12, wherein the anode material is disposed over substantially a whole of the interior surface of the support structure. 14. The catalytic device of claim 12, wherein the cathode material is disposed over substantially a whole of the exterior surface of the support structure. 15. The catalytic device of claim 12, wherein the layer of the cathode and the layer of the anode material are each divided into a plurality of sections to form a plurality of fuel cell portions. 16. The catalytic device of claim 15, wherein each section extends substantially a length of the support in a direction of exhaust flow. 17. The catalytic device of claim 15, wherein the plurality of fuel cell portions are electrically connected in series. 18. The catalytic device of claim 12, further comprising a casing having an oxidant inlet configured to supply an oxidant to the cathode material. 19. An apparatus, comprising: an engine; and an exhaust system for conducting exhaust emitted by the engine and including a catalytic device configured to generate a voltage and to treat emissions from the engine, the catalytic device comprising: a support having an interior surface and an exterior surface; a plurality of fuel cell portions, each of the plurality of fuel cell portions comprising a cathode formed adjacent to a portion of the exterior surface of the support and an anode formed adjacent to a portion of the interior surface of the support; and a catalytic conversion portion disposed adjacent at least one of the plurality of fuel cell portions. 20. The apparatus of claim 19, wherein each anode and each cathode extend substantially a length of the support along a direction of exhaust flow. 21. The apparatus of claim 19, wherein the catalytic conversion portion comprises a three-way catalytic structure formed on at least a portion of the anode structure. 22. The apparatus of claim 19, further comprising a casing containing the support. 23. The apparatus of claim 22, wherein the support comprises an upstream end sealed to the casing via a seal. 24. The apparatus of claim 22, wherein the casing comprises an oxidant inlet configured to provide an oxidant to the cathodes for consumption in the plurality of fuel cell portions. 25. The apparatus of claim 24, wherein the oxidant inlet is configured to provide air to the cathode. 26. The apparatus of claim 24, wherein the oxidant inlet is configured to provide lean exhaust to the cathode. 27. The apparatus of claim 19, wherein at least two fuel cell portions of the plurality of fuel cell portions are electrically connected in series. 28. The apparatus of claim 1, where the fuel cell portion is configured to consume unoxidized and/or partially oxidized exhaust components of the exhaust. 29. The apparatus of claim 1, where the catalytic conversion portion and the fuel cell portion share a common internal structure. 30. The apparatus of claim 1, wherein the catalytic conversion portion is further configured to reform hydrocarbons in the exhaust emitted by the engine to form more fuel for the fuel cell portion.
