1. A fuel cell system comprising:
a reformer that has a tubular shape extending in an axial direction and reforms raw fuel into fuel gas;
a plurality of cell stacks that are arranged radially outward of said reformer in a circumferential direction to face said reformer in a radial direction and generate electric power from said fuel gas and oxidant gas; and
an exhaust-gas combustor that is arranged radially inward of said reformer to face said reformer in the radial direction and burns said fuel gas that is not used and included in exhaust gas from said plurality of cell stacks,
wherein each of said plurality of cell stacks includes a plurality of flat plate type cells stacked in the radial direction.
