Abstract

The present application discloses a startup process control method for a fuel cell system, comprising: causing the hydrogen subsystem, air subsystem, and thermal management subsystem of the fuel cell system to operate in their respective first state modes for predetermined first time periods; after the first time periods, causing the hydrogen subsystem, air subsystem, and thermal management subsystem of the fuel cell system to operate in their respective second state modes for predetermined second time periods, wherein if before operating in its second state mode, the anode side pressure or cathode side pressure of the fuel cell stack in the air subsystem is less than a predetermined pressure value, then in the first state mode of the air subsystem, the fluid pipeline between the cathode gas outlet of the fuel cell stack and the exhaust discharge subsystem of the fuel cell system is first opened and then closed; if before operating in its second state mode, the anode side pressure or cathode side pressure of the fuel cell stack in the air subsystem is equal to or greater than the predetermined pressure value, then in the first state mode of the air subsystem, the fluid pipeline between the cathode gas outlet of the fuel cell stack and the exhaust discharge subsystem of the fuel cell system is directly closed.
