A fuel cell system includes a reformer, fuel cell stacks, and an exhaust-gas combustor. The reformer has a tubular shape extending in an axial direction and reforms raw fuel into combustion gas. The fuel cell stacks generate electric power from the fuel gas and oxidant gas. The fuel cell stacks are arranged radially outward of the reformer in a circumferential direction to face the reformer in a radial direction. The exhaust-gas combustor burns fuel gas that is not used and included in exhaust gas from the fuel cell stacks. The exhaust-gas combustor is arranged radially inward of the reformer to face the reformer in the radial direction. Each fuel cell stack includes flat plate type cells stacked in the radial direction. This achieves downsizing of the fuel cell system.
