Abstract: An active fault-tolerant temperature control method for a proton exchange membrane fuel cell system is disclosed. Firstly, a model of a proton exchange membrane fuel cell temperature control system is established, and a system structure matrix is established according to the model by structural analysis. The system structure matrix is decomposed by using a Dulmage-Mendelsohn method, a redundant part of the model is obtained, and a system residual is constructed to reflect faults of the temperature control system. On the basis of fault identification, sliding-mode-based active fault-tolerant control is designed to accurately control an outlet temperature of a stack. The new method solves the problem of sensor failure of a temperature control model of the proton exchange membrane fuel cell system during operation, and applies model-based fault-tolerant control to temperature control, so that the reliability and durability of the fuel cell system can be effectively improved.
