Patent ID: 8859136

Claim:
A fuel cell system comprising: a fuel cell module for generating electrical energy by electrochemical reactions of a fuel gas and an oxygen-containing gas; a combustor for raising the temperature of the fuel cell module; 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 electrical energy generated in the fuel cell module to electrical energy according to requirements specification; a control device for controlling the amount of electrical energy generated in the fuel cell module; and a casing containing the fuel cell module, the combustor, 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 includes a casing body defining an interior, and an open/close door that opens/closes the casing body using a coupling member as a fulcrum point, the open/close door is movable between an open position wherein the casing body is opened and a closed position wherein the casing body is closed, the open/close door having an inner surface facing the interior of the casing body when the open/close door is in the closed position, and an outer surface opposite to the inner surface; the power converter and the control device are attached onto the outer surface of the open/close door; the casing further includes an outer plate detachably attached to the outer surface of the open/close door to cover the power converter and the control device, and the outer plate is detachable from the outer surface of the open/close door and the casing body to uncover the power converter and the control device while the open/close door is in the closed position; and the open/close door is detachable from the casing body in a state where the power converter, the control device, and the outer plate are attached onto the open/close door.
