What is claimed is: 1. A reformer for a fuel cell system, the reformer comprising: a first body; a second body in an inner portion of the first body and having a first end and a second end opposite the first end, wherein an inner portion of the second body comprises a heat source unit for generatin
What is claimed is: 1. A reformer for a fuel cell system, the reformer comprising: a first body; a second body in an inner portion of the first body and having a first end and a second end opposite the first end, wherein an inner portion of the second body comprises a heat source unit for generating heat; a reforming reaction unit including a reforming catalyst provided in a space between the first body and the second body for generating a hydrogen-rich gas from a fuel through a reforming reaction using the reforming catalyst; and a nozzle member within the heat source unit, the nozzle member comprising a substantially pipe-shaped body extending from the first end and having a portion closer to the second end than the first end, the nozzle member having a plurality of nozzle holes each extending transversely through the substantially pipe-shaped body, wherein the nozzle member is partitioned to have a plurality of regions adjacent to one another along a longitudinal axis of the nozzle member, and wherein the nozzle holes are arranged in a nozzle pattern that is substantially similar within each of the regions and that is different between at least two of the regions for distributing the fuel and an oxidant substantially uniformly throughout the heat source unit. 2. The reformer of claim 1, further comprising a path member connected to the second body and in the inner portion of the first body for venting a combustion gas generated by the second body from the first body. 3. The reformer of claim 2, wherein the path member has a shape of a coil. 4. The reformer of claim 2, wherein both the first end and the second end are substantially closed, and wherein the first end is provided with a first hole through which the nozzle member is inserted into the inner portion of the second body, and wherein the second end is provided with a second hole through which the combustion gas is vented. 5. The reformer of claim 4, wherein the path member is connected to the second hole. 6. The reformer of claim 4, wherein the first body has a third end and a fourth end, both the third end and the fourth end being substantially closed, and wherein the third end is provided with a third hole through which the fuel is injected, and wherein the fourth end is provided with a fourth hole through which the hydrogen-rich gas is vented. 7. The reformer of claim 6, wherein the third end of the first body is provided with a fifth hole through which the path member is extracted. 8. The reformer of claim 1, wherein the substantially pipe-shaped body of the nozzle member has an opened end and a closed end, and wherein the nozzle pattern is configured to distribute the fuel and the oxidant in the inner portion of the second body. 9. The reformer of claim 8, wherein the closed end of the nozzle member is in the inner portion of the second body. 10. The reformer of claim 1, wherein the plurality of nozzle holes have different sizes according to the regions. 11. The reformer of claim 1, wherein the plurality of nozzle holes are separated by different intervals according to the regions. 12. The reformer of claim 1, wherein the first body has a third end and a fourth end, both the third end and the fourth end being substantially closed, and wherein the third end is provided with a first hole through which the fuel is injected, and wherein the fourth end is provided with a second hole through which the hydrogen-rich gas is vented. 13. The reformer of claim 12, further comprising a path member connected to the second body and in the inner portion of the first body for venting a combustion gas generated by the second body from the first body, wherein the third end of the first body is provided with a third hole through which the path member is extracted. 14. The reformer of claim 1, wherein the reforming catalyst has a pellet shape. 15. The reformer of claim 1, wherein the heat source unit includes an oxidation catalyst in the inner portion of the second body. 16. The reformer of claim 15, wherein the oxidation catalyst has a pellet shape. 17. The reformer of claim 1, wherein the first body and the second body are cylindrical. 18. A reformer for a fuel cell system, the reformer comprising: a thermal insulating outer body; a heat source unit in an inner portion of the thermal insulating outer body and having a first end and a second end opposite the first end, the heat source unit for generating heat; a reforming reaction unit provided in a space between the heat source unit and the thermal insulating outer body for generating a hydrogen-rich gas from a fuel through a reforming reaction, the reforming reaction unit surrounding the heat source unit; and a nozzle member within the heat source unit, the nozzle member comprising a substantially pipe-shaped body extending from the first end and having a portion closer to the second end than the first end, the nozzle member having a plurality of nozzle holes each extending transversely through the pipe-shaped body, wherein the nozzle member is partitioned to have a plurality of regions adjacent to one another along a longitudinal axis of the nozzle member, and wherein the nozzle holes are arranged in a nozzle pattern that is substantially similar within each of the regions and that is different between at least two of the regions for distributing the fuel and an oxidant substantially uniformly throughout the heat source unit. 19. The reformer of claim 18, further comprising a path member connected to the heat source unit and in an inner portion of the reforming reaction unit for venting a combustion gas generated by the heat source unit from the reforming reaction unit and for uniformly distributing the heat generated from the heat source unit to the reforming reaction unit. 20. The reformer of claim 19, wherein the path member has a shape of a coil.
