[Problem] The object is to provide a fuel cell system capable of ventilating the interior of a casing in a simplified construction and also capable of suppressing the drawing of combustion gas into the interior of the casing even if such gas remains around the casing at the worst. [Solution] The system comprises a reforming apparatus 21 for generating reformed gas from fuel gas, a fuel cell 11 capable of generating electric power with reformed gas and oxidizer gas, a cooling passage 80 opening to the outside of a casing 70 for leading cooling air which cools an interior of the casing, into a receiving space in the interior of the casing through an inverter system 15, an air blower 31 for introducing cooling air from the outside of the casing to the cooling passage, and a breaker for cutting off a circuit to a power line when the fuel cell system falls in abnormality or is to be subjected to maintenance, wherein the casing receives the reforming apparatus, the fuel cell, the inverter system, the air blower and the breaker in the receiving space and wherein cooling air introduced by the air blower from the outside of the casing is led to the receiving space after cooling the inverter system, whereby the pressure in the receiving space is kept higher than the atmospheric pressure. |
