Claim Text:
1. A fuel cell system comprising: a fuel cell module for generating electrical power by electrochemical reactions of a fuel gas and an oxygen-containing gas; a fuel gas supply apparatus for supplying the fuel gas to the fuel cell module; an oxygen-containing gas supply apparatus for supplying the oxygen-containing gas to the fuel cell module; a water supply apparatus for supplying water to the fuel cell module; a power converter for converting direct current power generated in the fuel cell module to electrical power; a control device for controlling an amount of electrical power generated in the fuel cell module; and a casing containing the fuel cell module, the fuel gas supply apparatus, the oxygen-containing gas supply apparatus, the water supply apparatus, the power converter, and the control device, wherein the casing is divided by partition members into a module section where the fuel cell module is provided, a fluid supply section where the fuel gas supply apparatus, the oxygen-containing gas supply apparatus, and the water supply apparatus are provided, and an electrical equipment section where the power converter and the control device are provided; and one of the partition members, which divides at least the module section from the fluid supply section or the electrical equipment section, includes a recess recessed toward the module section, and at least any of a fuel gas pipe of the fuel gas supply apparatus as a passage of the fuel gas, an oxygen-containing gas pipe of the oxygen-containing gas supply apparatus as a passage of the oxygen-containing gas, and a water pipe of the water supply apparatus as a passage of the water is provided in the recess, the fuel cell system further comprises heat insulating material surrounding the fuel cell module, the heat insulating material has a circular shape in a plan view or a polygonal shape in a plan view, the polygonal shape having a circular arc shaped portion at a corner, the recess has a substantially triangular shape in a plan view, the triangular shape slopes along a peripheral surface of the circular shape of the heat insulating material from an end of a plate that extends along the peripheral surface of the circular shape of the heat insulating material, or slopes along a circular arc surface of the circular arc shaped portion of the polygonal shape of the heat insulating material from an end of a plate that extends along a flat surface of the polygonal shape of the heat insulating material.
