Abstract: The invention discloses an emission control system. A vehicle-mounted solid oxide fuel cell system using the emission control system comprises a stack and a burner. The emission control system comprises an EGR intake pipe, as well as an exhaust cooling device, a supercharging device, a gas storage device and an EGR valve connected in sequence by the EGR intake pipe. An inlet end of the EGR intake pipe is connected to an exhaust pipe of the burner, and an outlet end of the EGR intake pipe is connected to an inlet pipe between the stack and the burner. This solution adds an EGR system to the original vehicle-mounted solid oxide fuel cell system. As the introduced exhaust gas can reduce the ambient temperature of the inlet gas, the generation of pollutants such as NOx can be reduced. In addition, after the EGR exhaust gas participates in combustion, the combustion temperature is further reduced, thereby inhibiting the generation of pollutants such as NOx. The present invention also discloses a vehicle-mounted solid oxide fuel cell system comprising the foregoing emission control system.
