To restrain the leakage of an exhaust gas from inside of a fuel cell module to the outside of a fuel cell system. A simplified airtight housing 4 constituting a SOFC system accommodates a fuel cell module 1, an exhaust gas processing unit 2, and a heat exchanger 3. A SOFC package 7 accommodates the housing and defines and forms an auxiliary machinery compartment 8 around the housing. The housing has an intake hole 41. A blower 17a disposed in the housing draws in air from the inside of the housing and supplies the air to air electrodes of fuel battery cells in the module through a cathode air supply passage 17. The suction of the air from the inside of the housing by the blower maintains the inside of the housing at a pressure that is lower than the pressure in the area surrounding the housing (the compartment). |
