Claim 4:
5. The active fault-tolerant temperature control method for the proton exchange membrane fuel cell system according to claim 1, wherein the active fault-tolerant control structure in step S4 mainly comprises the sliding mode controller, a fault detection module, and a control module; the fault detection module judges, according to parameters of a temperature, a pressure, a volume or a mass flow rate, and a voltage in the fuel cell system temperature control model, whether the sensor in the fuel cell system temperature control model fails, after the fault detection module detects that the sensor in the fuel cell system temperature control model fails, the control module reconstructs, according to the fuel cell system temperature control model, a sensor signal indicative of a fault and feeds the sensor signal back to the sliding mode controller, and finally, the sliding mode controller realizes the fault-tolerant control over the fuel cell outlet temperature by feedback.
