Empirical modeling of proton exchange membrane fuel cell performance using universal approximation theory of fuzzy system

Proton exchange membrane fuel cell is one of the most promising fuel cell technologies for transportation and residential applications. Modeling of fuel cells is getting more and more important as powerful fuel cell stacks are getting available and have to be integrated into power systems. In this paper, we used the universal approximation theory of fuzzy system to construct a PEMFC model, which is implemented on Matlab/Simulink software. The proposed model uses experimental data from the practical measurement when the system is provided with enough hydrogen. Considering the PEMFC output voltage as the output, the electric characteristic model of PEMFC is established according to the different PEMFC load currents and system temperatures. Finally, a good agreement between the simulated and experimental values has been achieved.
