An object of the present invention is to provide a favorable ventilation process with a simple and economical configuration and to improve the installation stability by satisfactorily shortening the dimension in the height direction. A housing constituting a fuel cell system includes a module part in which a fuel cell module is disposed, a first fluid supply part in which a fuel gas supply device is disposed, and an oxidant gas supply. The device is divided into a second fluid supply unit 114 in which the device 16 and the water supply device 18 are disposed, and an electrical component unit 116 in which the power conversion device 20 and the control device 22 are disposed. Inside the housing 24, from the air inlet 126 to the electrical unit 116, the upper part of the module unit 110, the first fluid supply part 112 and the air outlet 128, the first ventilation flow passage 132, and the air inlet 126 A second ventilation flow passage 134 connected to the electrical component 116, the air circulation port 124, and the second fluid supply unit 114 is formed.
