Abstract
To improve the stability and performance of fuel cells, the operating temperature of proton exchange membrane fuel cells (PEMFC) should be controlled within a specified range. However, most existing mathematical models of PEMFC are too complex to be applied effectively in the control process. In this paper, adaptive fuzzy identification and control models of PEMFC are developed based on input-output sampled data and experts' experience. The parameters of the identifier and controller are regulated by an adaptive learning algorithm, the network structure and the rule database are modified by adjusting the parameters. In the end, the simulation results of the online control model are presented and show the effectiveness.
