Besides, a continuous flow of water-ethylene–glycol (WEG) is delivered to the PEMFC coolant loop, so as to remove the heat from the PEMFC stack and to maintain the stack within the desired range of operating temperature, and this seems to be easier to be well implemented. When controlling an integrated PEMFC system, the comprehensive PEMFC system model and the associated advanced intelligent control systems are of great significance, for the sake of achieving faster dynamic response, longer lifetime, and higher efficiency of the PEMFC based energy conversion [8–10]. Particularly, an effective system model can reasonably characterize the operating parameter dynamics for the integrated PEMFC systems, which has laid the basis for optimizing the topology and control strategy of the fuel cell system. Noteworthily, the formulation and derivation of the advanced intelligent control strategies are highly dependent on the available control-oriented system model, while effectively formulating the on-line model based control strategies
