A study of modeling and control of proton exchange membrane fuel cell stack systems

At first, the cell structure and the working principle of proton exchange membrane fuel cell (PEMFC) were introduced. The architecture of PEMFC stack system was given aiming at its complexity. The system structure comprised the reactant supply, the process operation, water/heat management, the output adjustment and the system control of PEMFC. Then, on the basis of the existing PEMFC mechanism model and experience model, the mathematical modeling of PEMFC stack system was analyzed particularly. The partition of PEMFC structure and conditions, the foundation of PEMFC variable space, the choice of PEMFC description parameters and PEMFC model identification were presented. Finally, the research status and development of PEMFC stack system control were discussed, and the control characteristics of PEMFC stack system were studied. At the view of application, two projects of PEMFC stack system control based on fuzzy inference control and generalized predictive control were advanced.
