Document Type and Number:
WIPO Patent Application WO/2023/178946
Kind Code:
A1
Abstract:
Disclosed in the present invention are a fuel cell system and a control method therefor. The fuel cell system comprises a fuel cell stack module, a hydrogen supply system, an air supply system, and a cooling system, the cooling system comprising a water pump which drives a coolant to continuously flow to take away heat; and the fuel cell system is characterized in that the water pump is a water pump integrated with an expander, and comprises the expander, a water pump body, a water pump electric motor and a water pump controller, wherein the water pump controller controls the water pump electric motor to operate; the expander is coupled to one end of a rotating shaft of the water pump electric motor, and the other end of the rotating shaft of the water pump electric motor is coupled to the water pump body; and an exhaust tail gas resulting from an reaction is discharged using the fuel cell stack module, and is then input into the expander, the expander does work to drive the water pump body to operate, so as to provide power for the coolant of the cooling system to flow. The structural arrangement of the fuel cell system is rational and simple, the energy recovery problem of the exhaust tail gas of the fuel cell system is effectively solved, the utilization rate is high, and the efficiency of the fuel cell system is effectively improved.
