Claim 5:
6. The active fault-tolerant temperature control method for the proton exchange membrane fuel cell system according to claim 5, wherein the sliding mode controller is established according to the fuel cell system temperature control model, an input of the sliding mode controller is a fuel cell set temperature, an output of the sliding mode controller is a cooling water flow rate, and the cooling water flow rate serves as a control variable of the sliding mode controller; a sliding mode surface of the sliding mode controller is designed according to the fuel cell system temperature control model, and a smoothed switching function is adopted to prevent a pump from oscillating; and due to an excessive overshoot effect caused by an integral effect in the sliding mode controller, integral separation and anti-integral saturation methods are added to the sliding mode surface to accelerate system response capability and stability.
